Hi, I have someone wanting to sell me a like new a7 for $1100. Can't deny it, the specs and the full frame was what attracted me. But am being told that full frame is an overkill for what I want it for. I have a Canon 5D Mark II for events, and a 50D crop body as my daily walkaround camera (I literally carry it with me everywhere I go 90% of the time) just in case . I'm finally getting tired of carrying a DSLR and whipping it out on a daily basis, so I've been looking at replacing my 50D with a more portable mirrorless body. Don't want to adopt a new system, so will pick up an EF to E mount adapter. Here's what it will be used for: 1. Daily walkaround camera--cityscapes, street photography 2. Baby pics/family portraits at home 3. Travel camera, occasional landscapes 4. Backup to my 5D2 (weddings, birthdays, photoshoots etc.) *For all of the above, I'd like to be able to blow up prints to at least 20x30 *I hardly do sports or wildlife, so don't care about fps bursts What I like: full frame in small factor, high resolution, high dynamic range, high ISO, What I dont like: Slow AF with EF adapter Do you think a7 is a reasonable choice? Or is it an overkill?
