I’ve crumbled. It arrived this lunchtime. with the ftz and 24-70. I had a play with a friends on Wednesday and ordered one about an hour after getting back. Not tried it in anger yet, but the silent shooting and EVF is what pushed me over the edge. The mechanical shutter is really quiet too, wasn’t expecting that, so that’s another bonus. I have to say, first impressions are very good.
I tried my Tamron 70-200 G2 on my friends and it worked perfectly with the ftz. I was also impressed with his 24-70 f4. My own 24-70 f2.8 could be for sale shortly
