While the D750 is a fine camera, the D850 is considerably better - build quality, snappiness, buttons and switches vs need to access the menu, autofocus system (group AF helpful in some situations), metering (highlight protection spot meter is a time saver) I think the D850 is worth considering. I've used a D750 - and coming from a D200/300/700/3S/800/810 experience, I felt the D750 was a step back in handling. I have only held but not shot with a D850, and I predict it will feel more familiar in my hands.

Having bigger files and needing to buy more storage is NOT a reason to prefer the D750 over the D850. It just means that you will likely buy more storage a bit sooner. Storage is relatively cheap and getting cheaper. My first ever hard drive was a 10 mb (not tb or even gb) that I purchased in 1984 and it cost me $900. It didn't last me 6 months.

The 105 F1.4 is one of Nikon's sharpest lenses. But I think the Sigma is sharper. I've briefly shot with the Nikkor and thought it was pretty amazing. But what I am seeing with the Sigma may change all of that.

This is an interesting field test of both - and you can skip over the video from 3:31 to 4:27 - where he completely wasted my time with his absurd test in a failed attempt at humor - he should stick to photography.

The video page also has downloadable pictures that you can pixel peep to your heart's content.

I think I would likely end up getting the Sigma - better sharpness, nicer bokeh, more uniform brightness across the field - makes for better portraits. Both lenses vignette - and vignetting is easily corrected.

Hello all! I'm new to the forum and have searched previous posts but not found any recent on the above topics. Now that Nikon is moving a bit on the price of the D850, I'm back to asking the 'upgrade' question. I'm 99% sure I don't want to go mirrorless, but is it worth the jump to the D850? I'm no pro, but I don't use auto; I shoot RAW and do post in LR. Most of my photography is family/friends, dogs & horses and lots of lacrosse games. I never charge for pics (and try not to shoot at events where a pro is booked!), but they are used by many in announcements, holiday cards, gifts and social media. The upgrade would 'just' be for me - to get better and perhaps eventually make something of it...

Second question is another that I haven't found any recent posts on. My main lens is the newer Nikkor 70-200mm 2.8. It was a huge leap from the 70-300mm and has given me a much better appreciation for the better glass. I'm venturing into some portrait-ish work, and would like a prime to round-out my equipment. A 105mm seems to be the best fit. Most of the reviews I have found favor the Sigma, but it weighs more than the 70-200.

Thoughts?
