Thinking about getting the
Tamron 70-300mm f/4.5-6.3 Di III RXD Lens for Nikon Z, Mount, Full Frame
for my Nikon Z50 (DX)

Am I corr3ct in expecting the zoom to be 1.5 x 300 = 450
Am I correct?

I would usually use it for birds, etc. in a nature preserve.
Would this be a reasonable thing to do?
Am I giving up too many f stops?

On an APS-C camera body like your Z50 this lens will have a 35mm equivalent angle of view similar to 105mm to 450mm. Look for video reviews. One of the biggest drawbacks for you may be that this lens does not have image stabilization. It will make use of a cameras's internal stabilization if available, but unfortunately the Z50 doesn't have internal stabilzation.

I have found that the Z50 struggles with BIF, but is a delightful camera in most other situations. You should be looking at a lens with some sort of VR, however. If you don’t mind using an FTZ adapter, the Nikon AF-P 70-300 is a gem and on sale this month. I have personally used the Tamron 100-400 (F-mount) with good results birding.

Totally AGREE here ........ for wildlife, you really need at least 400mm on crop frame.

Until I picked up a Z9, I used a D500 for BIF. Until Nikon comes out with the Z 200-600mm f/? , I will continue to use my Nikon 200-500mm f/5.6 with FTZ II adapter. I use the 200-500mm on the Z9 with a 1.4x teleconverter. For birding here in SE Tx, I would not recommend anything shorter than 500mm.

I own the new Tamron Z lens and a Nikon Z50. Unfortunately, my Z50 is an infrared camera only so I don't use that combo for BIF. I did use it once with the Z50 with decent results for IR. Like someone mentioned, it's not a stabilized lens but being old school, none of my lenses were 20 years ago, so that doesn't bother me. It is a bit soft at the long end but not terrible. I've used it on a Z7II as well. I have shot BIF even with the Z50 and that Tamron lens but in IR. It can be done but even in bright skies I had to push the ISO to 800 to get a shutter speed at 1/1000 because of the slow nature of that lens. I can't say it's ideal for BIF on a Z50, but it can be done. It wouldn't be my first choice of a combo, but it's a good buy as a lens. The first image is from the Tamron lens, but on the Z7II. The second is with the Z50 and the Tamron lens. Both, I believe were near 300mm on the lens. I don't have a decent shot of BIF with the combo to show you mostly because I only took the lens out once with the Z50 and only made one attempt at it. I could see that pushing the ISO you can do it, but again, it's not ideal because it's a slow lens. However, in the top image you can see dragon fly, so the lens can be used for BIF. It's just not ideal with the Z50 IMHO, but yes, it is possible with the crop camera.

I can second the comment about the Nikon F mount 70mm-300mm AF-P lens. If you go this route with the FTZ, buy the FX version. It's built a little better than the DX version. The lens is very light and sharp all the way to 300mm. It also focuses silently and quickly, and even when not on sale is inexpensive.
