So I finally snagged an R7 and I'm super stoked to take it out to the local nature preserve next month to try and get some decent shots of the ospreys. I keep seeing people rave about the RF 100-500mm but that is way over my $1500 budget lol.
I saw the RF 100-400mm is way cheaper and light but some reviews say it's too dark for woods and I should maybe look at the Sigma 150-600mm with an adapter instead. But then I heard the Sigma has focus pulsing issues on the R7? Its all so confusing. What lens are you guys actually using for wildlife on this body that wont break the bank or my back?
Jumping in here. In my experience, you should avoid third-party lenses if you want consistent AF on the R7. Sticking with native EF glass on an adapter is the most reliable way to save cash without losing performance.
- Canon EF 100-400mm f/4.5-5.6L IS II USM
- Grab one used for around $1,100, its a beast.
- Canon Mount Adapter EF-EOS R
- Simple and works every time. That combo is way sharper and more reliable than the budget RF glass anyway.
Building on the earlier suggestion, I honestly think you should look at the native RF primes if you want to keep things light and affordable. I was skeptical about the f/11 aperture at first but the R7 sensor is actually really capable when you push the ISO a bit. Its way better than dealing with the focus pulsing on those older Sigma lenses that people complain about. Heres what I use for birds:
- Canon RF 600mm f/11 IS STM
- Canon RF 800mm f/11 IS STM I am very happy with the results I get from these. If things get a bit dark in the woods, I just run the files through Topaz Labs Photo AI and the noise basically disappears. It keeps the whole setup under your budget and your back will thank you after a long day at the preserve. Feel free to reach out if you need more tips on setting up the AF for birds!
I got the R7 last summer and had the same headache trying to find a lens that didnt cost as much as a used car. I actually tried one of those third-party lenses with an adapter because I wanted the extra reach, but man, the autofocus issues were real. Every time a bird moved, the focus would just hunt back and forth. It was super frustrating and I missed some killer shots. You really gotta be careful with adapted glass on these newer mirrorless bodies... it isnt always smooth.
- Stick with native glass if possible
- Be wary of weight for long hikes
- Focus speed is usually more important than total reach Honestly, just get any of the newer telephoto zooms from Canon. You cant go wrong with their native stuff. Just stick with Canon and youll be much happier.
I definitely agree with the point about sticking to native glass. Reliability is everything when you're out in the field. From what I've gathered, the R7's autofocus system can be a bit more temperamental than the full-frame models, so going with native RF or adapted EF is probably the safest route to avoid those pulsing issues. Not totally sure about the exact pricing right now, but IIRC you might want to consider older used professional primes. These often offer much better weather sealing than the entry-level zooms, which is important if you're shooting near water. Just be careful and make sure to check if the glass supports the R7's maximum burst rate. Someone told me that certain older lenses can actually limit your frames per second, and that would be a real problem for tracking ospreys. I would suggest checking the official compatibility lists before you buy anything... just to be safe.
