REVIEW: Canon Rebel T6s/760D with 18-135mm f/3.5-5.6 IS STM Lens (Part II of II)

Click to learn more
Canon EOS Rebel T6s/760D DSLR Camera (Body Only)

In the first part of my review, entitled REVIEW: Canon Rebel T6s/760D with 18-135mm f/3.5-5.6 IS STM Lens (Part I of II), I covered pretty much everything except for my bookshelf shots. As a result, I’d encourage you to read that now if you haven’t already.

In this installment I’ll finish up with a few more unedited real world snapshots and the bookshelf shots and give my final verdict.

Real World Snapshots Part II of II

As usual, these are all in-camera JPEG’s that have not been modified in any way outside of the camera beyond the filename and metadata. No changes have been made to the crops or color, so click to see the full-size originals to see exactly what you could expect if you took these photos.

You may view these photos for informational purposes, but you may not print, edit, upload, share, display, etc… these images for any reason without my expressed written and signed consent. ALL RIGHTS RESERVED!

Most of these shots are taken using camera default settings in Aperture Priority mode and Auto White Balance with no flash unless otherwise noted.

For more, click here for the first part of my review OR click here to view the full gallery.


f/5 @ 50mm for 1/1600 sec at ISO 100

The kit lens is sure to please beginners and those who have never had premium lenses


f/5.6 @ 18mm for 1/40 sec at ISO 400

f/5.6 is the sweet spot of this lens so my lack of a tripod on this trip forced me to settle for a lot of f/5.6 shots to keep my ISO as low as possible. For static subjects like this the image stabilization performed well.


f/5.6 @ 85mm for 1/125 sec at ISO 1000

Aspiring photographers will appreciate the easy access to exposure compensation via the Quick Mode Dial (not found on the T6i) to help with shots like this


f/5.6 @ 35mm for 1/60 sec at ISO 200

Pinch to zoom on the touch screen is super handy to do a quick verification to make sure you got the shot for handheld images like this with lots of detail


f/5.6 @ 27mm for 1/160 sec at ISO 320

The on-camera flash isn’t as bad as some that I’ve seen, so its better than nothing in a pinch


f/5.6 @ 18mm for 1/40 sec at ISO 160

Like all Canon’s, the default settings give great results with healthy warm skin tones that aren’t too far from reality (vs Nikon where they are more accurate but make people look ill unless you adjust the white balance away from the default setting)


f/5.6 @ 18mm for 1/160 sec at ISO 100

Since the kit lens doesn’t come with a hood, flare can be problematic. As a result, I’d highly recommend purchasing the hood to avoid unwanted flare.


f/7.1 @ 74mm for 1/640 sec at ISO 100

Under the right conditions this lens is sure to please…


f/5.6 @ 27mm for 1/30 sec at ISO 6400

But indoors is where both the lens and sensor will most likely disappoint parents

Bookshelf Test

Using a tripod, mirror lockup and a timer with camera default settings, I take these bookshelf shots to show off how a camera and/or lens performs under controlled testing. In this test, the 18-135mm kit lens performed very well at 18mm, but not so well at 135mm. The sharpest results are shown below for 18 & 135mm respectively.


f/5.6 @ 18mm for 8 sec at ISO 100

Click the above image to see it full size and zoom around. What you’ll notice is that it is laser sharp in the center and then it starts to get softer (blurry) with text the farther you get out to the edges. This happens due to the distortion which is common at 18mm, yet this lens seems to have quite a bit of distortion.


f/8 @ 135mm for 15 sec at ISO 100

Click the above image to see it full size and zoom around. What you’ll notice is that it is reasonably sharp, but not nearly as good as 18mm. This is typical of zooms – especially ones that span so much zoom range. There is some distortion even at 135mm, so I’d classify this as a lens worthy of its price. It’s not great, but it doesn’t suck either.


f/5.6 @ 18mm for 1/8 sec at ISO 6400

At its sharpest setting, this is showing the highest ISO I’d feel comfortable using. ISO 6400 is reasonably good, but 12,800 is only for emergency use. This is relevant because most parents photograph their kids indoors in very low light (typically lamps), and that requires high ISO’s to get the shutter speeds you need for the images to not be blurry when your kid is sitting mostly still.

Click the image above and zoom in to see how much digital noise you’ll see at ISO 6400 and the impact of the in-camera noise reduction (detail is lost during noise reduction). These results aren’t horrible, but there are other cameras out there that perform better than this.

18-135mm STM vs 11-24mm f/4L

The 11-24mm f/4L is one of the sharpest lenses Canon has ever made, so for kicks and giggles I thought I’d compare to see how this lens at 18mm f/8 compares with the 11-24mm f/4L. Nobody buying a T6s could ever afford the 11-24mm f/4L, so this is purely an academic comparison to show how sharp it is in the center but how that goes away quickly at the edges due to distortion.

(left) 18-135mm STM vs 11-24mm f/4L (right)
Center sharpness
Click image to zoom

In the shot above, I’ve zoomed in to show how the kit lens is extremely sharp in the center. You can click that image for a larger view, but it definitely is impressive in the center with these settings – especially since the lens on the right cost $3000 USD!!!

(left) 18-135mm STM vs 11-24mm f/4L (right)
Sharpness away from center
Click image to zoom

Now notice above that as you go to the you can see how the kit lens starts to get less sharp. Take notice of the words “Japanese Woman” and see how it feels like you need to put glasses on when you look at the left side, but the right is sharp. This is expected given the price difference of the lens, but this softness at the edges is something to consider when taking photos with this lens at 18mm.

Where you really see the difference is in the distortion you get with the kit lens as shown below:

(left) 18-135mm STM vs 11-24mm f/4L (right)
Distortion
Click image to zoom

Now before you start thinking that the 18-135mm lens is “just as good” as a $3k lens, keep in mind that this comparison is done with the best image I could get with the kit lens in controlled conditions. When you start to zoom or change apertures, the quality of the kit lens deteriorates quickly.

The lesson here is that if you need ultimate sharpness with the kit lens, f/5.6 or f/8 at 18mm is going to serve you well.

Conclusion

Overall this is a fun and easy camera to use that offers a little more functionality for people wish to go beyond the keeping the camera in full auto mode all of the time. The top LCD and Quick Mode Dial both make the T6s worth the extra money over the T6i if you can afford it. However, if you are never going to take the camera out of auto mode then don’t bother as these features are only for those interested in advanced shooting techniques.

I was very disappointed in the auto-focus (AF) performance of the STM kit lens, so those seeking something better should to look at my lens recommendations. Unless you are doing primarily video where STM is necessary, a non-STM lens is going to offer better AF performance. Even a slightly softer 24-105mm (which is easily found at a reasonable price on the used market) will offer much faster autofocus speed based on my real world testing.

I’d recommend this camera for amateur photographers, but I’d advise against it for parents. The Nikon D7200 is going to be a better investment for parents with a few hundred extra to spend. See my recommendations page for my latest advice.

Product Advisories

There always seems to be some white disc conspiracy theory with every camera that comes out these days, so camera makers are getting used to it. Canon has quickly issued an advisory and free repair offer for impacted customers should this happen to you, but I didn’t see this problem during my testing.

SIGMA has also issued an update to the firmware for their lenses when using Live View with T6x models. Click here to learn more.

REVIEW: Canon Rebel T6s/760D with 18-135mm f/3.5-5.6 IS STM Lens (Part I of II)

Canon EOS Rebel T6s DSLR Camera with EF-S 18-135mm f/3.5-5.6 IS STM Lens
Canon EOS Rebel T6s DSLR Camera with EF-S 18-135mm f/3.5-5.6 IS STM Lens

The Canon T6s/760D is probably the most advanced and exciting Rebel series camera I have ever used. It has all the ease of use and advanced features of a typical Rebel, but it takes it to the next level by adding the top of camera LCD that is typically reserved for the next step up (70D at the time this was written):


Top View with LCD not found on the T6i

The T6s adds the following features not found on the T6i:
  • A top LCD panel (shown above) which experienced photographers will appreciate
  • HDR movies – this seems to only be available in SCN mode so I didn’t try it for this part of my review.
  • An electronic level which is handy when you are on stabilizing your camera on a tripod or surface
  • A quick control dial on the rear panel which I found to be invaluable (see below)

Quick Mode Dial
Quick Mode Dial


Front Screen Out View

I’ve become a big fan of the tilt out LCD that allows for selfies and tricky macro shots. The touch screen sensitive seems to be much improved over the T5i which I found to be too sensitive for my taste. This time I found myself enjoying the touch screen and loving this LCD quite a bit.
Here’s a complete list of the T6s body features likes and dislikes during my testing:
Likes
  • AF Zones
  • A dedicated button to switch between single AF point, AF zones and full Auto
  • Touch screen support
  • Fully articulating LCD
  • Quick Dial
  • Top LCD
  • Electronic Level
  • Silent Mode
  • Built-in Flash
Dislikes
  • The insanely annoying power switch that requires you to stop in the middle for photographs as it easily goes straight to video.
  • Lack of a support for using the Q button to jump sections in the menus which is possible on the more expensive bodies.
  • Auto ISO stops at ISO 6400
  • No ability to set a minimum shutter speed in aperture priority
  • No exposure compensation in manual mode when auto ISO is enabled
  • Lacks 5D Mark III’s proper HDR mode (only minimalistic SCN mode offered)

Real World Snapshots

As usual, these are all in-camera JPEG’s that have not been modified in any way outside of the camera beyond the filename and metadata. No changes have been made to the crops or color, so click to see the full-size originals to see exactly what you could expect if you took these photos.

You may view these photos for informational purposes, but you may not print, edit, upload, share, display, etc… these images for any reason without my expressed written and signed consent. ALL RIGHTS RESERVED!

Most of these shots are taken using camera default settings in Aperture Priority mode and Auto White Balance with no flash unless otherwise noted.


f/5.6 @ 135mm for 1/1250 sec at ISO 100 Shade White Balance
Despite the cropped sensor, creamy bokeh was readily available with the kit lens


f/5.6 @ 50mm for 1/60 sec at ISO 320 -2/3 EV Shade White Balance
General scene shots contained plenty of detail and rich colors


f/5.6 @ 135mm for 1/1600 sec at ISO 320

I caught the bee in this shot, but the slow focusing kit lens was responsible for hundreds of misses. I also wasn’t very impressed with the weak dynamic range in this shot compared to what I could get with a more expensive Nikon D7200


f/7.1 @ 67mm for 1/640 sec at ISO 100 +1/3 EV
I was extremely pleased with this kit combo for this tough shot in mid-day sun with no clouds


f/4.5 @ 20mm for 1/40 sec at ISO 100 Shade White Balance
Like nearly all cameras, the face will generally take the priority
even in evaluate metering mode so the background will suffer


f/5 @ 20mm for 1/160 sec at ISO 100 Flash White Balance Flash
While the default flash settings are still a little blah for my taste, it does a reasonable job with no user intervention at capturing a clear shot of the subject and properly exposing the background. This will please amateur users who know to use Aperture Priority (vs Program Mode or Full Auto)


f/5.6 @ 18mm for 1/40 sec at ISO 160

With diffused natural light in your favor, a well balanced exposure is possible with more sharpness than you probably want for a portrait


f/5 @ 50mm for 1/60 sec at ISO 400 Shade White Balance
I didn’t see an option for setting the minimum aperture so potentially good family shots like this were ruined by subjective movement and a shutter speed that is too slow for kids


f/5 @ 50mm for 1/200 sec at ISO 100

In harsh mid-day sun once again the evaluate metering mode favored the human subject but this camera lacks the dynamic range to save the details lost in the hot spots on the arms. Nevertheless it made the right tradeoffs for a keeper shot for amateur & family users.


f/5 @ 50mm for 1/1600 sec at ISO 100 Shade White Balance
This sensor doesn’t do especially well with pure reds, but the farther you get away from pure red the better it does. In this case I thought it did a respectable job under harsh conditions.


f/5.6 @ 108mm for 1/1600 sec at ISO 200

Here’s an example where I thought this camera did a excellent job in harsh daylight and in this case the AF managed to focus properly on the busy bee


f/6.3 @ 35mm for 1/500 sec at ISO 2000

This kit lens is plenty sharp and this sensor is no slouch up to ISO 3200

Videos

Here are a couple handheld videos with stabilization turned on and auto ISO at 1/60 sec in manual mode:

Unless you invest in some video stabilization hardware, you can easily see that this isn’t going to perform as well as your camcorder or cell phone which is true of ALL DSLR’s. This is a common frustration point for amateurs who mistakenly assume they’ll get camcorder performance from a DSLR especially when they feature these STM lenses (which are really just silent motor lenses).

Click here to see more videos that have been professionally edited and shot using stabilization equipment. Great video is possible, but it’s not point and shoot easy like a typical camcorder or cell phone.

T6s vs iPhone 6

The iPhone 6/6+ is a very impressive camera phone, so I decided that for a couple shots I’d do a head to head comparison for my own curiosity. What follows are the results where you can click to see the original and compare them side by side on your local computer. I’ve included my observations below:


T6s f/5.6 @ 24mm for 1/30 sec at ISO 100
For this image I appreciated the better bokeh and separation between the subject and background with the T6s. I also felt that the color was more natural as it appears in real life.


iPhone 6 f/2.2 @ 29mm for 1/120 sec at ISO 50

This is a gorgeous shot to view on the iPhone’s retina display with its rich colors. The small sensor means a 7.21 crop factor so this is more like a f/14+ shot so there’s lots of depth of field in the flowers which some might find desirable while others may hate.


T6s f/5 @ 59mm for 1/500 sec at ISO 100 -2/3 EV
The larger sensor meant more detail and bokeh in places, but the dynamic range was rather disappointing compared to the iPhone 6.


iPhone 6 f/2.2 @ 29mm for 1/860 sec at ISO 32

The f/14+ aperture once again favored the iPhone 6 resulting in a image with incredible sharpness overall with the only detail loss being in the smaller flower buds.

The iPhone 6 was definitely impressive, but anyone who loves color accuracy and the creamy bokeh that separates the primary subject from the rest of the image will certainly appreciate a DSLR – even an entry model like this T6s. However, I’d call the iPhone 6 images “good enough” for those non-critical images you take for fun (i.e., the food shots) – especially after a one click edit with Perfectly Clear

Conclusion

See my conclusion here in part II, but overall I felt this is a good starter camera. While I don’t think the image quality will satisfy 70D, 6D and 5D Mark III users seeking a second camera body, it does seem to be roughly on par with the 7D Mark II.

I was very disappointed in the AF performance of the STM lens so I’d encourage those that can afford it to look at my lens recommendations. Unless you are doing primarily video, even a slightly softer 24-105mm (which is easily found on the used market) will offer much faster autofocus speed based on my real world testing.

Conclusion

I wasn’t a big fan of the Nikon super megapixel D800/D800e because it was so easy to get blurry shots and honestly it’s more megapixels than people really need. I expect more of the same for these new Canon’s, but it will still be fun to see what they have to offer.

The new lens is a great addition to the lineup, but its nearly $3000 price tag is too much for my blood. I was pretty happy with the 8-15mm so I can’t see spending nearly twice as much for this one.

The Rebels area always where Canon innovates and offers amazing value – this is true here once again. These are awesome cameras at excellent prices. Pair one of these with the SIGMA 50mm f/1.4 Art Series and I’ll bet it will destroy most of the images people are getting with the new 7D Mark II. I can’t wait to review the T6s!
