Pros: Great image quality, the lens ecosystem is wide open (I've been shooting with a lot of old Minolta glass), very small and light body. The electronic viewfinder is a great feature; the ability to use a level, focus peaking, grids, zebra stripes etc while looking through the viewfinder is invaluable, especially if you're shooting manual focus.
This camera is ergonomically great! Being able to reach all of the dials for shutter speed/aperture/whatever you program them for without taking your hand off the grip is hugely appreciated.
Cons: On the expensive side, especially for first-party native lenses or if you want to use pricey auto focusing adapters.
The battery life is also pretty bad, as a result of Sony trying to keep the battery consistent across A-series bodies. I'd say you probably have 300-400 shots on a charge.
While the camera itself is light, the first party lenses are typically about the same weight as the body itself! I wouldn't be surprised if my zoom lenses start developing creep from how far they pull the body down while I'm carrying it.
Lastly, this is a minor nitpick but Sony seems to have included "DLC" for their A-series cameras. What this means is that you have to pay to unlock certain features, such as the ability to keep the shutter open for longer than 30 seconds (I believe it's an extra $4.99 but I could be wrong). I suspect you'd be dissapointed if you bought this camera for astrophotography and wanted to use it right out of the box.
The bottom line? This is a cool piece of technology with a few glaring flaws. However, if you want to pick up a cheap mirrorless full frame, I'd say that it's your best option. I've included some sample photos that have only been minimally processed.
So ... I took my excellent Sigma 30mm f2.8 from my Nex 6 and removed the baffle ( a common mod since then the Sigma can cover full frame). And there is a very, very tiny amount of vignetting at f2.8 and is actually very good up to around f4. All the vignetting is so light it can easily be removed in Lightroom. But that lense is absolutely tack sharp in the IQ department. Check all the reviews ... This is a $199 lens that rivals the new Sony FE 35mm f2.8 at a fourth of the cost (with the baffle removed ... 3 tiny screws and 3 minutes of work).
Then I researched and got the Samyang 14mm f2.8 super wide. This lense retails for around $348 on amazon, and has been tested by different mags and dozens of reviews to be practically equivalent to a $1400 super wide. You can get this lens under the Rokinon branding. The only thing is, of course, is that you have to use this lense with an adaptor to the e-mount. Since I use the inexpensive Sony LEA-1, it does not auto focus (the lens would not support it anyway) ... So you have to manually focus. I find that with this lens, the A7 peaking function is a little off or uncertain, so I simply assign the C1 custom button to the focus magnifier function and eyeball it without peaking instead.
But ... My star lens is the Sony A-mount SAL50M28 50mm f2.8. I put this beauty on the A7 via the LEA-1 adaptor, and beautiful things happen. That A7 is predictable and dead on accurate. And the peaking is full off until exactly (not almost) in focus. That makes manually focusing with mid level peaking fast, effortless and very accurate ... An absolute pleasure to use. This is the only lense I have used thus far that makes me feel just as comfortable shooting as I do with auto focus shooting. Plus (the very best part) the lense is unbelievably sharp and flat across the frame. When I saw that 16 people on Amazon gave it five stars, I was skeptical ... But now, I'm a believer. Amazing sharpness and even though, yes 50mm is handy for macro work, this lens is da bomb for street photography. Chances are I will rarely take this lens off my camera. Even for 50mm landscape shots, a 100% crop reveals individual pine needles on a pine tree at 120 yards away ... With dead on color and absolutely no noise or optical distortion. The lens is completely flat and is about 1:1.1 or 1:1.2 ... In other words, subjects in your images look the same size as what your eyes see.
This $598 sony 50mm just boosted the sharpness of my A7 to what seems to be slightly beyond 5D MIII territory. And finally that lens, with the small Sony adaptor attached is about the same size as the original A7 kit lens. Before, I just had a pro camera ... Now I am getting pro images out of it. What a difference! All else with the camera is high quality, pro build and everything I could hope for in manual control functions that are all easily assignable to the many physical controls that are easily and intuitively placed around the camera. So now, with an Nex-6, a Canon T2i, a Sony RX1 and my new A7, I finally feel like things are reasonaby well covered. But the A7 takes me into another league altogether. It's easy to carry with me, I get pro results, it's rock solid, ultra configurable to the way I want to shoot, etc. We're having fun now.
UPDATE: I was so impressed with the leap in IQ from the Alpha A-mount lenses that I purchased the LA-EA4 adaptor. This is the adaptor you want ... fast AF and actually much smaller looking and feeling than what the pictures of it on the camera would seem to indicate. If fact, I am so impressed by the auto focusing response and lightness of the unit that I decided to simply make the A-mounts my lens collection. Of course I save a lot of money, but once I research the lenses for 5 star average reviews, I can buy them at around 50 to 60 percent what the FE lenses would cost. So far, in addition to the (not so sharp) 28-70 kit lens that came with the A7, I have the A-mount Sony 50mm F2.8 ($450), the Sony 50mm F1.4 ($550), and a SUPERB Sony 100mm F2.8 ($800). These are all full frame lenses and the pros who have used them are virtually unanimous on their virtues.
At first glance it may seem that I do a lot of macro work since the 50f2.8 and 50f1.4 and 100f2.8 are all hyped as macro lenses. But, even though they seem to be superb at macro shooting, my purpose was use in street photography. Everyone knows the 50mm is preferred by many street photographers, thus the purchase of the two 50mm lenses. But, sometime I don't want to get too close to my subject so that I can capture the moment without them feeling uncomfortable or ruining the look and feel I am trying to capture. The 100mm f2.8 gives me that bit of telephoto but is still razor sharp like a good quality prime should be. It let's me be about twice the distance away while shooting and still fill the frame with my subject scene.
IMHO ... A KEY TO GREAT IQ ON THE A7 ... No matter what you've heard about 1/60th of a second being fast enough to freeze the action in street scenes, switch to M (manual mode) on your mode dial. Then set your Aperture to either shallow depth of field (f1.4-3.2, etc) or deep depth of field (f8-16) and put the shutter speed at minimum 1/320th second. With this camera you have nothing to worry about when in Manual mode. Your auto focus still works, you select the aperture you want for bokeh or for focus across the frame with one of the two horizontal dials, then set, and forget, the shutter speed to 1/320 to 1/500th second with the other horizontal dial.
The reason why this setup is key is that the lack of sharpness the A7 sometimes exhibits in images can be traced to too slow of a shutter speed. Now you may be thinking, "Well ... DUH?" But remember, in addition to hand steadiness, you can also have camera vibration from the shutter event itself. Your hand may be relatively steady, and your subject relatively still, but camera vibration can still sabotage your shot ... even at 1/60th of a second. A fast shutter speed will capture the picture before the vibration "echoes" reverberate through the camera body. Forgive the technical stuff, I'm a scientist by training :) When you leave the shutter speed at this fast speed, you only have to decide which effect you want your aperture to have and set it. THE COOL THING IS ... the A7 will continue to set the ISO automatically for you, if you have set the menu selection for ISO to AUTO. So, your shot always turns out! You can even set the bracketing for AUTO ISO in the menu system to make sure the camera does not select an ISO that is too noisy (higher than 3200 or 6400). While the A7 can remain relatively noiseless until around 3200, a shot at 6400 is completely usable in all but the largest print sizes ... and 6400 shots are better than missing the shots. That's why I set my upper ISO limit to 6400. Shots that have a little ambient light usually never take my A7 above 1600-3200 ISO so I'm usually safe.
So, you can see that shooting in M, with the shutter frozen at faster speeds, then simply choosing Aperture for whatever you happen to be shooting that day, can be like an AUTO mode since the camera will make it all right for you with the AUTO ISO. I usually agree with the ISO the AUTO ISO sets, so I'm happy. The end result of this coffee-powered write-up is that, with the shutter speed at 1/320 to 1/500, the 100% crops on my images have improved in sharpness by close to 300% from what they were when the camera selected 1/60th to 1/80th sec shutter speed. Again, I think this is likely due to camera vibration rather than lack of steady hand ... though both are important. With the kit lens, I now have a family of 4 lenses, 3 of which produce great IQ, that auto focus fast and produce very good results. It may be a long time before I feel the need to buy any FE lens. I know they will be good, but they are somewhat expensive. With the A-mounts, I spent a lot less getting my kit outfitted (and let my wallet cool off), plus, I have everything I need today ... instead of having to wait a year or two. The key to this plan was the LA-EA4 adaptor which only adds about 10-15% to the overall size and mass of the camera plus lens unit. You have a great camera! Enjoy it.
