Some great pics and suggestions,thanks. To be honest I'll probably just keep the camera hanging around my neck to take pics while in the blind. I see lots of interesting things there. I think I could get by with a fixed lens,maybe 100mm? Definately need the longer lens. Anything would be an improvement over my phone pics,LOL.
I think you'll be surprised at how little zoom 100mm actually is. You're going to want 300mm minimum. Sigma makes a 120-300mm Sports lens that is great and, as stxranchman said earlier, the 150-600mm is also a great lens that will cover pretty much every focal distance you'll need to cover in the deer blind.
I was taking these to show him as you responded to his post. 1.6x cropping factor on each pic using a 100-400mm zoom lens and the feeder is just over 85 yards from my front porch. Set on 400 IS with no editing or cropping and handheld. It was very low light with foggy mist , so they are darker.
Here is 100 mm (160mm equivalent)
stxranchman, you definitely the man, have admired your buck photos for years. I like the comparison at different focal lengths for the OP. Most folks, me included, initially think you can grab a camera, for cheap, and get great photos(like wysiwyg thru binocs). My eyes were opened years ago attempting to shoot my kids basketball & volleyball games. Most pics came out dark & blurry. Little did I realize that it takes expensive cameras, and even more expensive lens, plus some practice/luck to get good photos!
OP, 100mm can be used if you get within 20 yards, say in a bow blind. Might still need to crop some to get what you want. Be sure to get a camera with a silent shutter or game could be spooked at that range. I've had mixed experiences with that, but quieter is better. Superzooms are silent, mirrorless can be set to electronic shutter and silent, while some dslrs have a silent mode, but are still relatively loud. At 50 yards, no big deal either way.
I like the option of a variable lens so that if a critter pops up at 10 yards, or crosses a trail at 400, I can still get a pic without changing lens. Sigma has a new 60-600mm zoom lens for dslr cams that looks appealing.
I just grabbed a couple of skulls and a box of shells for size reference, stepped out in the mist & shot these from 50 yards so you can get an idea of what the higher zoom/reach gives you in photos. That buck photo I posted earlier was at 370 yards & 3200mm equivalence after cropping.
600mm
800mm
1200mm
2000mm
Good luck on your quest, but be careful, wildlife photography can become as addictive as hunting.
