Do I really need these two Tamron lenses?

[TCav]

The D800E has a 'Full Frame' sensor capable of 7,360 × 4,912 pixel images, but with an APS-C only lens attached, the resolution drops to 4,800 × 3,200 pixels. That's less than the 6,000 × 4,000 you get with your D5300, or the 5,568 x 3712 you get with your D7500.

To be able to take advantage of the greater resolution of the 'Full Frame' D800E, you should get 'Full Frame' lenses, but you'll still have trouble beating what you're getting with the Tamron 17-50/2.8 on your D5300. Equivalent 'Full Frame' lenses are 24-70/2.8, but optically, they don't perform as well as the Tamron.

'Full Frame' cameras are capable of better image quality, but 'Full Frame' lenses have trouble delivering it.

Looks like I'll have to get a proper wide angle lens before my upcoming vacation next month.
I'm going here for the fifth straight year. This website was my best year there:

I'm going to keep the 17-50mm f/2.8 as it will be a nice range between 26-70mm or so with my D800E and D7500... I5MP is still good enough, better than my old D700 12MP. Anyways, I just bought a mint Nikon AF Nikkor 20mm f/2.8 Lens for landscapes. What do you think of that lens?

From https://www.opticallimits.com/nikon_...kkorafd2028ff:

"The Nikkor AF-D 20mm f/2.8 is able to deliver very sharp images straight from its largest aperture. Stopped down to f/5.6 the sharpness is on a very high level across the whole FX image.Optically however it is not without flaws. Vignetting is on a rather high level, especially for larger apertures. CAs are also quite pronounced, however they are easy to correct in post processing.

Nonetheless, the lens is quite compact and leight-weight. So, compared to optically better lenses (like the Nikkor AF-S 14-24 wide angle zoom or the manual focus Zeiss ZF 21/2.8) it may still be the more attractive option for those who want to travel light. Especially since it's also quite a bit more affordable."

What I have is the Nikon AF Nikkor 20mm f/2.8 Lens (without the D) this is the lens before the D came out.
I had one with the D700 a couple years ago and really liked it then. I'm pretty good with my Adobe CS6 software so should be no problem.

"The Nikkor 20mm f/2.8 is a very wide prime that has been around for quite a while. The still current AF-D version of the lens was introduced in 1994, however the basic design goes back to the Ai-S version, which was brought to market in 1984 already. Just like the optical formula, other properties remained unchanged through the years: it is rather compact and light-weight, and also quite affordable for a relatively fast prime."

I updated my signature. I now have the D800e with Nikkor 20mm f/2.8 and my Tamron 17-50mm f/2.8 will work well with it as well in DX mode.
I got this setup for Landscapes that I do a lot of. I've also updated my 20 year old website if you care to look:
https://moskovita-photography.com/
For some reason it's not letting me attach files???

[jack55]

To see the difference between the Nikkor FX 20mm f/2.8 and Tamron DX 17-50mm f/2.8 with the D800E here is a photo of my Birding area in the backyard.
(Why is this forum not allowing "attach files" anymore???) (now I have to upload to my server and use a link to the image icon at the top)

I did no editing or cropping except to resize to post here to show you the difference between a FX & DX lens.
First pic is taken with the Nikkor FX 20mm f/2.8


Using the Tamron DX 17-50mm f/2.8 the D800E automatically went to DX mode at 17mm and about half the resolution

I'll be keeping the Tamron 17-50mm f/2.8
