Interesting dilemma: Nikon Z7 with Nikon 200-500 mm lens vs DX cropped with Nikon 28-300 mm lens.
Jan 18, 2020 23:18:10 #
I have found that the Nikon Z7 (full frame) can easily convert to a DX setting.
So, if I use my 28-300 mm lens, I can convert the magnification to 1.5x the 300 mm end, ie give the photo the equivalent of a 450 mm setting. Is this good or bad to do. It will save carrying the heavy 200-500 mm lens, as well as the 28-300 mm lens, for my travels. I know that when cropped the Megapixels drops from 46 MPX to 20 MPX. Is this terribly important as I am an amateur photographer?
Your thoughts would be appreciated.

I dont have your camera, but I'm sure it's not magnification, it's just cropping, as in regular cropping, throwing away the unused pixels, so no advantage to your image. If you took the 500 you could crop that to look like a 750.

My thoughts are that nobody can answer this question for you (however you will get many strong opinions here telling you what to do).
My thoughts are:
(1) if you shoot in DX mode with the 28-300 that is no different than cropping to the same angle of view (same size). Using DX mode gives you the longer field of view but you lose the information that was cropped and you lose resolution compared to the 200-500.
(2) you should take your 28-300 lens and 200-500 + FTZ and Z7 and shoot with both in various situations, DX, FF, just having fun nothing serious, and then decide for yourself what works best and why.

Try just cropping the image in post processing, and see if there is any difference. BTW, there is no magnification change when you crop. All you are doing is narrowing the field of view. The 28-300 is clearly not in the same league as the much better 200-500.

First the 200-500 is a far superior lens to the 28-300 having used 2 of them for weddings for many years .
Second a 300mm is a 300mm and will put the same size image on the sensor whatever the crop factor . The lens does not become 450mm its still 300. Its all abou pixels on Image and the 200-500 will give you more and a lot sharper

Actually it's angle of view.

That may well all be true, but it doesn't address their concerns.

Will there be a difference?
Yes, all things being equal, yes.
Will the difference be noticeable at user enlargements?
Probably not.
At 8X10, no ... at 16X20 ... maybe ... it all depends on distance from the final print.
Billboards are printed at 1 or 2 PPI and look fine ... from a mile away.

Trying to help here.
In an earlier post you said you had a D3100.
That with a 28-300 will produce a great image at a 450 effective FL.
I would take that over the expense of buying a Z7 and 200-500.
If you already have a Z7, I still don't think I'd opt for the 200-500, but thats me. I was ready to jump on one of these until I saw the size and weight.
If I could introduce a third option, a used 300/4 will give you equal or better optics than a 200-500, has a full 1 stop faster speed, weighs about half and costs a fraction used.
That all being said, I'd take the 28-200 out and shoot several shots at DX mode ... D3100 is DX full time of course ... and do a 16-20 enlargement with your best shot and see if you are happy.
That, only you can answer.

There is no point in trying to use any 300 or 500 mm lens on a camera that does not have fine focus adjust so a D7100 up would be the minimum.

I think cropping in post changes the apparent angle of view in an identical way to switching to the crop mode in camera, no? The lens still projects the same size image circle onto the sensor in both scenarios.

I have a Nikon Z7 not a D3100 (my wife^s camera) .
Thank you all, for your interesting comments. Guess I will just have to experiment and compare results. I thought I might have gotten out of taking my heavy 200-500 mm lens to Antarcticta, but I think now I will take it anyway.

Can you explain your reasoning on that? Not saying you are wrong, just wondering why you think so. Especially a mirrorless camera that focuses directly from the sensor?
