Originally posted by Mattox It know it seems rediculous to jump the gun before he full frame even comes out but the question is......: how will this camera compare to the Nikon D 810 and its vast array of lenses? I am so tempted to ditch my Pentax gear and move to Nikon seeing how well the 810 is performing. The only thing that is holding me back is a little bit of faith, a dash of patient, and the fact that if I were to jump ship would I be able to get rid of my Pentax line up (k5, 16-50 sdm, da 55-300, da 35 f2 and smc 50 a 1.7
Here is my take.
1. Pentax FF is just a month away, I think all you need to do is go out and shoot more picts and all of a sudden, that 1 month will have arrived. (ie. don't think too much at this point, 1 mth is easily over with some distraction)
2. There are some unknowns that we kinda know (ie. pixel shift; on camera SR; GPS and astrotracker; pentax handling; pentax interface; pentax WR; pentax smallish lenses) ... These are things that will make me choose Pentax over D810 already.
3.There is the practical and the theoretic imo (and somehow forums tend to drive folks towards the latter).
Practically means you already have the lenses. You go out the door with what you have, and you make the picts using your eqpt to the best than you can muster at that time.
The Theoretical means you just sit down facing the beautiful sunset, and lament on the 'what it could have beens'.
Your eqpt is already good, going D810 also means D810 quality lenses (added costs), going the Pentax FF route means you only spend on a new camera, esp when its not really preventing you making nice photos.
4. The cameras of the same lineage nowadays are really very close to each other in performance.
People can go I up you this you up me that, but the reality when looking at it w/o side by side comparisons is very little difference.
Which is why I think ppl like to go for DXO numbers nowadays.
Since they themselves can't prove it in picts, they point to harder to derive (so harder to reposte) numbers from DXO.
So Pentax FF, D810, A7RII, A7R, the difference will really be very little and often a win some lose some in different aspects of the camera/system
5. As for lens selection.
The often used stick to beat at Pentax.
So how many lenses does someone who says such a thing actually buy?
I often see many such folks get Sigma, Tamron on the Canikon over the OEM lenses.
Not that all the users don't buy OEM lenses, just that its often over emphasised.
You already have some lenses, some work in crop mode, and 2 work on FF, better than starting from scratch imo.
