I’m trying to pick a DSLR-compatible Canon telephoto lens for wildlife photography in low-light conditions (also, I like doing urban candid photography/street photography from distances, so that too). Naturally, this means high ISO and low f-stop. For some reason, all I can find are like f-4; is that normal? Also, what’s with all the “telephoto” lenses that max out at 200mm? Shouldn’t something like 400mm be better? I suppose I don’t want something too bulky, so 400mm is probably pushing it but idk… if you have experience in this, let me know what you think. I can only seem to find a handful of options, and most are for mirrorless cameras which sucks because I don’t want too many camera bodies so getting ANOTHER one for this purpose would really clutter my shelves as I don’t have any mirrorless Canon’s.
Anyways, budget is tight, nothing north of $1000, let me know what you think!
Edit: Posted in wildlife photo community, but it was dead (no posts since like 2 months ago) so figured I’d move it here.
Unfortunately, you’re asking for the worst-case scenario for lenses. This has to do with physics, and how much glass is required to shape the light onto the camera sensor. These lenses exist… but the prices are ooof
