Hey Guys,
Thank you for all of the input and suggestions.
Since I wrote this inquiry, I have done a bit of internet research and I have determined three things...
A..I definitely want to upgrade from my NEX-7
B..I am more thoroughly confused as to which way to go, A7 or A7R
C..I am even more confused as to the lens that I want to start with
I also want to redefine my needs..
1. My goal is to have a camera that will, first and foremost, be my everyday carry camera. This means I will carry it in my bag and pull it to shoot anything, at anytime. People, architecture, whatever interests me in my travels, day or night. Will I have/use a tripod? If necessary, but mostly I will exercise long term proven camera handling skills for steady shots. Since I will shoot anything, the focal range needs can vary, from wide for architecture and travel to longer (and shallower DOF) for people.
2. Secondly, with vertical grip attached (a must for me), it will function as a professional backup to my 1Dx and/or MFD gear on location. In this respect, I shoot people with strobes 90% of the time. In the Canon world I use an 85 f1.2 at f2.0 or a 70-200mm f2.8 at f2.8 and generally around 100-135mm. In the MFD world, I use the 110mm f2.8 exclusively. I rarely (never) shoot above f2.8.
Since my 1Dx is 18MP and my Credo is 60MP, my inclination is to go with the A7R and fall right in the middle at 36mp. However, at the same time, since I shoot people, and the absence of an aa filter is sometimes not kind to people (skin blemishes look worse, etc.), the A7 seems to have a lead.
From what I read, the phase detection AF in the A7 is not appreciably better than the contrast detection AF in the A7R. For better or worse, I am used to the contrast detection in the NEX-7.
I like that the A7 is supposed to flash sync up to 1/250, whereas the A7R is only up to 1/160 if I read correctly. (Not that important.)
I like that the A7 has a slightly faster burst rate. (Not that important.)
I like that the A7 has a higher ISO range (Seems pretty advantageous since as a carry it has greater versatility)
I like that the A7R has more resolution. I have printed many 30"x40" prints and some 40"x60" prints with files from my old 1Ds Mark III. (important)
I like that the A7R has a full magnesium body instead of a mix of magnesium and plastic. (I like great build quality)
As for lenses, the 50mm, that Jim K. mentioned, seems like a good all-around carry/travel lens, however, a longer f2.8 or faster lens will be needed for people. Something between 85mm and 135mm. What lenses are recommended in this category?
As my indecision continues....LOL
Is this therapy or a photography forum? LOL
