Why? Because I'm stupid
No just kidding. I went from a 10D > 20D > 40D > 7D > 5D3 all upgrades. So I sold the 7D to buy the 5D3. The 5D3 has been with me for about 3yrs (I think) and I got a lot of nice shots with it, especially with the 70-200/F2.8. But at a certain point I started to deny paid shoots and the 5D3 stayed in the bag very often, in the long term WAY too often to justify keeping it. I then started browsing my LR catalog and saw that for 2014 I had +11.000 shots in the library, about 214 shot with the 5D3+70-200. With other lenses : 1.815 shot with the 5D3, all others with my mirrorless Sony cameras. So than I took the plunge and sold all my Canon gear, mainly too because I noticed prices were dropping so I would not lose too much. Good thing: + 5.000 euro waiting in the bank, bad thing : no more FF.
But as times goes by, I started to notice the shortcoming of my mirrorless setup. Mainly in AF speed and reach. And while the a6000 is very very good, I still lack nice fast zooms and in low(er) light, AF is just not there. Also, AF consistency went down mainly because I started to rely way too much on face detection and other stuff. I almost became a piont&shooter.
As it is now, quite a few people begged me to do some (paid) work for them, and this is work where I will not fully trust the Sony to satisfy my needs. So I started looking into a new SLR. The money I'll be making with these small assignments is too good to pass up on, so I might as well invest it in new material. The way I see it : not doing these assignments = 0 money, doing them = a small investment on top of that to get back into the (FF?) race.
This afternoon I visited my favorite shop and played around with some cameras, and also got some nice price quotes for both the 7D2 and Nikon D750. Keep in mind I'm not a sports shooter, portraits/people is about 90% of what I do. This is what I get :
D750 + 24-120/F4 : € 2.700 (a very nice rebate, normal price is around € 2.900!)
7D2 + 17-55/F2.8 : € 2.372 (- € 100 cashback)
I suppose depth of field between F2.8 on apsc vs F4 on FF is about the same, so for a price difference of about € 400 I can get a FF with from what I've read a better sensor and quite a bit more reach (both wide and tele). Added bonus is I can always add a nice 1.8 prime for that extra 'ff' bokeh. The 7D2 on the other hand is faster and has way more (cheaper) lenses for reach should I ever need it. For now I think a reach of about 120mm will do.
It's just a matter now of deciding if the better sensor is worth 400 euro. Hope this clears things up a bit.
