The other day I was doing some eBay browsing because I'm going to looking into getting a mid-range utility zoom and was shocked when I noticed both the 24-85 VR and the 24-120 f/4 VR were selling for almost the same price used. So I have experience with both lenses because I've owned 24-85 VR TWICE, but one was on DX which I didn't like and when I went full frame, I picked up another 24-85 VR wiched I used for a while and then upgraded to the 24-120 f/4 VR and kind of had nothing but complaints. It's an oddly large and awkward handling lens in my opinion, it was just kind of uncomfortable to use on a D6xx body. Probably was better suited for the D750 + D8xx bodies. Though, my MAIN complaint was zoom creep which some people had and some didn't. For the price of this lens, they should've put a lens lock on it. However, I dealt with it and one thing I noticed was that there was hardly any difference in image quality that I could see. In fact, the 24-85 VR was actually sharper around the edge. The difference between f/4.5 and f/4 is so little that you will never notice. Also 85mm vs 120mm isn't that big of a difference as it sounds. So what do you get with the 24-120 f/4 VR that you DON'T get with the 24-85 VR? Well you get slightly better build quality, slightly better weather sealing, NANO coating (which I believe is on only one element or two), possibly slightly faster and accurate auto focus, and I mean SLIGHTLY. You also get a better VR technology which is great for video work. Now the most important benefit you get with the 24-120 f/4 VR is that fancy gold ring! Which adds to the cost and makes you feel good. So why are these two lenses approximate the same price now in 2018? I believe people finally caught on with the 24-120 f/4 VR being an overrated lens and the 24-85 VR being an underrated lens. So the 24-120 f/4 VR sells new for what? $1100? At Least it was first released. I paid nearly $800 for my copy a year or two ago. Now they are selling used on eBay and there is an abundance of them for less than $500. I sold mine under $500. I lost money on this deal, it was a bad decision on my part. When I bought my first 24-85 VR, I paid like $250 used and it was nearly brand new. Now they are selling about $400 which almost the cost of a brand new one! Yes, you can find cheaper copies if your lucky, they might be missing the lens hood or the box or they might have some superficial marks on it. So for anyone who is looking for a good all-rounder utility zoom for their first full frame DSLR, I'm going to suggest the 24-85 VR over the 24-120 f/4 VR even if the prices are nearly the same. There are other alternatives in the Nikon lineup such as the 24-85G non-VR which can be had for very cheap. The 24-85 2.8-f/4 is also decent and many people's favorite seems to to be the 28-105D 3.5-4.5. They are all great options, however they also all lack VR and for someone who does shoot video occasionally on their DSLR, having VR is very handy in that range. Anyways, these are all my own developed opinions from past experiences. Your experience may differ. I decided to write this post in hopes that it might help someone who is looking at buying a utility zoom for their full frame body.
