I did alot of research after looking for about the same thing OP was,with what little I do know .
I just picked up a Canon sx160 is 16x optical zoom/16mp. $99 with,bag,charger,sdmicro,rechargable AA batteries.
I wanted small.light,long range able decent quality hunt & outdoors NM camera. Inexpensive.
I just took some pics this morning on my walk and they came out pretty good so far with the advice on how to w/digital info folks above posted.
I took one low zoom shot standing @ mesa behind me from 1/4 mi away. Downloaded to pc and I could see not only a survey stake but the sticks on the ground ,clearly.Wow,what a difference a decent camera makes. I'll post some pics of critters,the cattle ones I took from 400 yrds away I could see wiskers on them zoomed in on pc.
The anvil mtn is Alegres Mtn,in background in several of Randy's OWOA NM hunts.
Only peak in lower 48 above 10k that is all private,not gov......trivia.
