From what i've read so far, the Nikon 850 has no high ISO advantage over the 810D which does not perform better than the K-1. That said, you already have your 645 lenses. why are you thinking of switching platforms to not upgrade from the 645D?
Originally posted by 2351HD I have seen high ISO samples and the 850 seems a solid stop better than the 810, so that would put it on par with the 645z.
But this new gen BSI sensor would have increased dynamic range as well.
However, like you Mike I would have to ask why the OP wouldn't just upgrade to the Z.
Only reason is if he wants a more versatile system and lighter weight.
It's a tough call, if I still had the 645D I would consider the same as Pentax aren't paying much attention to the 645 system.
But then what about the replacement (if ever) to the 645Z? It will leap them all again like the Z did the first time.
Hi and thank you all, sorry, Ive been rather busy this week.
My reason for thinking of moving from Pentax is that I run into a lot of problems trying to do certain things, like working thetered, using the camranger, and HSS, although doable with the 645D and Z. It doesn't work as good or as easy as the other brands, it works with some strobes and not others, with some cameras and not others, and in my case it requires to stack two triggers on top of the 645D, already a big camera, so with the XT1 and the Cactus V6ii stacked on top it's annoying and bulky. I could buy another Cactus V6ii for every light I own, but that's expensive and silly.
And finally, Pentax is almost non existent in Mexico, everything is double the price and service is hard to find and slow.
But the thing I care about the most is image quality, which encompasses Dynamic range, Color depth and Resolution with usable high ISO.
That's why I'm asking, I've never even used a D810. If the IQ is similar to the 645Z, will it make sense changing to that system, for overall compatibility? But that's only if I get very similar quality. Sadly there's no rental market here to test the cameras, and I can only do it at the shop, which is not ideal.
Thanks again.
