Folks,
I appreciate everyone's comments here. This is great stuff and for those who have the Df congratulations on your purchase it's a lovely camera.
I've made a decision and I am going to pass on the Df for now.
Here is my reasoning (not trying to burst anyone's bubble!)
- On the low ISO end, I miss out on 1 stop increased DR, pretty sure I can live with that.
- On the high ISO end, the D700 is pretty decent to 3200. Seems similar to Df at 6400. I have my D700 auto ISO maxed out at 3200 and that has worked for me. Df High ISO is incredible, 25600 looks similar to D700 6400. So clearly, I'm losing out here. For those who are new to digital I HIGHLY suggest learning the Auto ISO feature of your Df. It's a gift.
- Resolution increase of 4MP not worried about it.
- Keep the 1/8000 shutter (oddly I have quite a few pictures over 1/4000)
- Keep the AF (which I'm pretty happy with)
- I don't own any manual lenses, my eyes aren't good so I doubt using some nice MF Zeiss would magically become significantly easier
- Lose on weight but I don't think it matters, the Df is still "chunky" as it should be for F mount lenses (otherwise would be too small). If I can curl a 65lb dumb bell with one arm, I shouldn't be complaining about 300 grams.
- I have big hands and the D700 controls work really well for me. Perhaps the Df controls would work for me, but need to play with it. Maybe I'll rent one.
As for A7(R). I'm going to pass too. The fact that there is one native lens right now that people say is closer to 40mm than 35mm and isn't too great doesn't excite me. As for adapted lenses, what works and what doesn't seems to be all over the place. I'm not into experimenting.
There are also reports that the RX1 is faster in operation than the A7(R). I find this hard to believe because the RX1 is piss poor slow in dim lighting conditions. It's a camera you need to be very patient with. I would expect more from the A7(R). So will pass on being an early adopter at least for now. I think it makes sense to see what Zeiss's next move is in terms of lenses.
Sorry if I bored you! The RX1 and D700 will remain in the bag.
