The Sony Cyber-shot DSC-RX1 has generated quite a bit a buzz for offering a full-frame sensor and an outstanding 35mm f/2.0 Zeiss lens in a camera that’s about the same size as your average point and shoot. This is the technological breakthrough that many have been anxiously waiting for – true full frame performance in a compact package. However, the real question is is it worth its staggering $2,798 USD price (at the time this article was published)?
Bokehlicious – yes, this is what a great f/2 lens on a full frame camera should look like!

Let’s just cut to the chance so I can answer the question that everyone wants to know about – is this camera really as good as a full frame DSLR? From an image quality perspective, the answer is without question – YES! The sensor on the RX1 is fantastic and the lens is on par with my best L lenses on my Canon gear. It’s got gorgeous color, dreamy bokeh at f/2.0, and creates sharp images even when examined in RAW. It’s high ISO performance is on par with most of today’s DSLR’s as shown below:
Based on what I’m seeing I’d call the dynamic range of this camera as average with today’s DSLR’s. I don’t think it blows any away, but it’s very good – and way better than anything in its class. The above shot was a normal exposure and the shot below was an in-camera HDR. On a wide gamut display the orange feels more vibrant on the shot below, but on a sRGB display they are about the same. Both shots were hand held.

The 1/80 sec issue
This camera has a love affair with 1/80 sec. It seems that the only speed it wants to shoot at when in creative, program mode or aperture priority is 1/80 sec. 99% of my shots in those modes when auto ISO was engaged were at 1/80 second which is odd given the fact that with a full-frame 35mm lens on a DSLR would typically drop down to 1/40 sec under these same conditions. Now, I can understand Sony’s desire to keep the shutter speed a little higher to avoid blurry subjects, but I’d prefer that to be a camera setting for minimum shutter speed.
Living at 35mm on a full frame
It amazes me when I talk to students who seem to think that smaller f-stop numbers only mean lower ISO’s and more light. They are often quick to run out and buy a 50mm f/1.8 lens thinking that they can shoot f/1.8 all day indoors and avoid having to use a flash. Sure, that might be true if you are only doing very shallow DOF shots, but the reality is that you’ll probably miss a lot more shots doing that due to the challenges of shooting at f/1.8.
The RX1 can go to f/2.0 which typically on a camera this small means nothing due to its small sensor, but this is a real full-frame sensor so f/2 means you do get dreamy bokeh AND shallow depth of field. Given the back focusing issue and this reality, it means it’s easy to foul up shots if you go to a shallow depth of field.
Of course distance from the subject and focal length also come into play when it comes to creating dreamy bokeh, so f/2 isn’t going to give you that if you take in larger scenes (as shown above). With 35mm you have to physically get close to your subject to get the dreamy bokeh like shown below and the top of this article, but if you can you’ll be rewarded.
This camera convinced me that I will never again own a fixed length lens camera again – especially a measly 35mm. I’ll make sacrifices for the ability to optically zoom and longer focal lengths are a must to me.
That said there are occasions where 35mm is the right focal length and having f/2 available can be just the ticket to blur out ugly backgrounds and make lights dazzle.
Back focusing Problems
One serious issue present in my test RX1 was major back focusing issues. Through the LCD you are fooled into thinking that you have the shot like above, but at actual full zoom you really see the problem:
Now before the Sony fan boys pull out the pitchforks, this issue isn’t limited to squirming toddlers. Here’s one of 20+ shots where the AF failed with every possible thing in its favor:
Even with support and 1/250 sec shutter speed it couldn’t focus properly on this big stationary Christmas tree. It seemed that if given a light and dark subject in the scene, it will always focus on the light subject no matter what you tell the camera you want it to do with the flexible focus point. This can work to your advantage sometimes, but many times it can frustrate.
I’m not a video guy so there’s not much for me to report here beyond the fact that the video looks great for basic work. The auto focus was a little slow, but that’s common for DSLR’s and the steady shot is no substitute for an external stabilization solution – just like with a DSLR. It’s still no camcorder, so your cheaper point and shoot or cell phone will be much more mom/user friendly, but this will give the real videographer much better results.
The sad thing about the in-camera HDR is that you can’t use it if you are in RAW mode, so you have to switch to JPEG only for this feature to work. They do have a dynamic range expansion feature that will work on your JPEG’s when you are in RAW+JPEG, but I still prefer Fujifilm’s single exposure EXR mode found on the X10. Here’s a quick example with just its dynamic range expansion and with its HDR Auto mode engaged (both handheld in very low light):
Now with HDR mode:
It did a decent job of aligning the images and getting the shot. Naturally a tripod would be best for the sharpest result, but with no light in this room directly (only spill from outside and an adjacent room) I thought the results were very good – especially for hand held.
Sadly it doesn’t keep each of the exposures it takes either, so you only get the final output. This means a decision to go in-camera HDR is a final one.
My bookshelf test clearly demonstrated what a great sensor this camera has. The colors are excellent, the detail is very good and the performance across the full spectrum of ISO’s from 100 to 25,600 is on par with the best DSLR’s on the market.

Overall I’d have to say this is a great beginning, but not something I’m interested in at this time. I loved the image quality and I commend Sony for using such a great lens. However, I need a zoom lens on a form factor like this and this is one camera that I’d actually consider buying if it had interchangeable lenses.
It’s just lame being stuck at 35mm only at this day and age, so at this price point it’s more of a proof of concept camera than something I desire to own. Hopefully Sony will respond to feedback like this and come up with an interchangeable lens version or one that has a decent 24-100mm zoom. Current lens physics dictate that a 24-100mm on any full frame camera at a decent aperture (like f/4) would be roughly the same size as Canon or Nikons 24-70 2.8mm lenses, so it’s no wonder Sony chose to go with a 35mm prime, but that just doesn’t fly with me.
If you are someone who only uses 35mm and think that the only thing that matters is a combination of size and image quality, then this is the perfect camera for you. The RX1 has a brilliant sensor and a fantastic lens in a compact package so you won’t be disappointed.
Keep trying Sony – this was a great start!
