Hello fellow e-mounters, It's been a while since I've been over here, spending most of my time over on mu-43 as I own two GH4's, and a host of m43 lenses (f/2.8 zooms, fast primes, telephotos, etc.). I switched over to the m43 system after a short stint with an NEX-6, but as they always say, "the grass is greener...". I am very happy with the switch, as the m43 system is quite excellent IMO, and has served me well so far. However I recently decided to purchase a set of three Canon FD lenses along with a focal reducer, to give me a set of fast, manual focus primes that weren't focus-by-wire, allowing me to generate some nice, steady and smooth focus pulls. This is when the itch began... I have a Canon FDn 24/2, 50/1.4, 100/2, all of which I'm very happy with using on my GH4. With aids like focus peaking and focus magnification, obtaining focus is quite easy. However the one thing that has left me somewhat unsatisfied with my m43 gear is loss of detail/smudging when really pushing the RAW files with shadows. I recently got in to doing long exposures and sunrises/sunsets, and can't help but think the better ISO performance of a FF sensor (roughly 1.5 stops over the sensor my GH4 according to DXO, FWIW), paired with a 1-stop lower native ISO (100 on an A7 vs 200 on my GH4), could make a difference when it comes to shooting difficult scenes with lots of shadows where I want to maintain detail when manipulating the RAW file. If I do pick up a FF camera, I'd add an FDn 35/2 (I really like the 35mm FoV), a 20/2.8 (something wider than 24mm is very helpful when shooting indoors or in tight cities), and an 80-200 f4 L (I use my 35-100 f/2.8 a surprising amount of the time on my GH4, so this would give me equivalent FoV and excellent image quality). I'd like to spend around $1000, less if possible, which leaves with me three options: An original A7 An A7R An A7II I have no problem buying used (almost every lens/camera body I own I've purchased used, and haven't had any issues yet *knock on wood*). I'd likely not be looking to buy until after the new year, since I'll likely rent a camera for a few days over Christmas break. This may be advantageous for me though, since body prices will continue to fall, and we may see some more used bodies pop up after Christmas when Santa brings people their upgrades . The benefits of the A7II are obvious, with IBIS being useful for shooting prime lenses, as well as larger grip (the GH4 fits my hand perfectly, and the A7II looks like it should be close). It also has an additional customization button, which may come in handy (I love all of the customization on my GH4's). Right now I see them going for around $1100, +/- $50. I figure after the new year the used prices will drop to around $1k. The A7R would be great with its 36MP and no AA filter, but I don't know if I need 36MP, the original A7-style body doesn't seem as ergonomic as the new one, and the shutter is obviously quite loud, something that may not be advantageous when shooting indoors or at night. It lacks IBIS, which is a nice feature to have when shooting stationary objects hand-held. I'm seeing used prices hover around $900-950 currently. Then there is the A7, which I have the same general concerns about the A7R: no IBIS, body design, etc. The big benefit of the original A7 is that it's cheap, as I've seen prices around $650-750. So, I'm all ears for anyone who has some advice to share, keeping in mind that I'd be picking this up to use strictly as MF with Canon FD class. Maybe some people have had experiences with multiple cameras I've mentioned above, and can shed some useful light on my situation. Anything is appreciated! And I've included some images below of the type of shots I'd be looking to replace using my GH4 with an A7 with. Thanks!
