I understand my Nikon D5600 is not full frame. What exactly does that mean? Will what I see in the viewfinder be in the picture? will it be bigger, smaller? I guess it has effect on the lens as well. So what does a 200 - 400 zoom lens show as.
Keep in mind that you are talking to a digital newbie, please don't throw around terms that "I should know".
Thanks Hoggers
If you have never used 35mm film cameras or "full frame" digital cameras.... it doesn't matter at all.
You're D5600 can use most DX lenses
and most FX lenses (full frame design)
DX lenses are designed specifically for crop sensor cameras. FX lenses are designed to accommodate full frame cameras. They need to produce a larger image circle in order to fully cover the larger image sensor of the camera.... which usually makes for bigger, heavier and more expensive lenses.
Focal length is focal length... there's no difference. A 50mm lens can be DX or FX (most actually are FX). But the point is that 24mm is still 24mm, 50mm is still 50mm, 85mm is still 85mm, etc. regardless of format.
How any given focal length "performs" on a camera changes a little. For example, on your D5600...
10mm to 15mm is an "ultrawide" lens
16mm to 22mm is "wide angle"
24mm to 30mm is moderate wide to slightly wide
32 to 35mm is "normal" or "standard" lens, not wide nor telephoto
40mm to 60mm is "short telephoto"
70mm to 135mm is "moderate telephoto"
150mm to 300mm is telephoto
upwards of 300mm is "super telephoto"
The same focal lengths on a full frame camera would "act differently"... for example, a standard or normal lens is approx. 50mm.
But, who cares! If you don't have preconceived notions about how a focal length might work, it doesn't really matter. Just buy lenses that will serve the purpose you want... wide, normal or telephoto... on your D5600. It really doesn't matter how those lenses might work (if at all) on a D750 or D5.
You actually need to be more concerned about some other things.... There are Nikon lens compatibility charts at the Nikon website and at Nikonians.org, as well as extensive information about the various Nikon lens designations, what they mean and various possible "issues" at Ken Rockwell's website. I suggest you start to get familiar with those. For example, your D5600 isn't able to autofocus all lenses made to fit Nikon F-mount cameras. The current Micro Nikror AF 200mm f/4D and Tokina AT-X and ATXi 100mm Macro lenses are twp examples that lack any sort of focusing motor built into the lens itself. Instead, to autofocus they rely upon a motor in the camera body.... which only Nikon D7000-series and higher models have. Therefore, those lenses would be manual focus only on your D5600. There may be some other compatibility issues, especially with older lenses. Those should be a greater concern to you than focal length or whether the lens is DX or FX design (since, in that respect, you camera can use both).
