EOS 90D - wildlife photography lens?

blanke — Thu, 03 Jul 2025 12:24:32 GMT

Currently trying to figure out which lens to get for my Canon 90d to start wildlife and landscape photography. I’m looking at the Sigma 150-600mm - but I’ve heard some mixed reviews on it. Hoping to get something that allows me to take super sharp photos, looked at the EF 70-300mm but really does not seem sharp or detailed at all. Appreciate any recommendations!! Thank you 🙂

Greetings,

The Sigma or Tamron 150-600 are two of the most popular lenses used for wildlife on DSLRs. Some also use the Canon EF100-400 with or without a 1.4x extender.

The EF 70-300 USM II does not have adequate reach for wildlife. Maybe if you were shooting a bird feeder in a backyard, but even then you'd be challenged. Don't get me wrong. It's a great lens, I still have one, (it's retired now) but I used it for distant landscapes, not for wildlife.

Rick nailed it, the two lenses he mentioned may be some of the most widely used lenses for wildlife. I used the Sigma 60-600mm on my 90D before moving to mirror-less and it functioned flawlessly, on both my mirror-less and 90D.

Hopefully ebiggs one will stop by, he strongly recommends the Tamron SP 150-600mm f/5-6.3 Di VC USD G2 often and normally tells people it's a great lens and to grab this lens over the G1.

If possible find a local shop that has both a try them both on your 90D. Either would make a great addition to you lens stable.

You can certainly go through the rather long list of lenses that will work or even ones that might work but if you want the best get the Tamron SP 150-600mm f/5-6.3 Di VC USD G2 for Canon EF.

Not that any of those lense aren't good they are but keep this in mind a bird is tiny and unless you are close , very close, it will remain tiny in your shots. "Very close" means feet not yards or meters. Now on the other hand if you are shooting elephants or grizzly bears you may not need as much FL or be as close (want to be as close) to subject.

But the Tamron SP 150-600mm f/5-6.3 Di VC USD G2 for Canon EF gives you that option. 600mm for that tiny bird and 150mm for the dinosaurs.

The Sigma C model is a good probably best second choice. I have one and it's a nice lens just not quite as good as the Tammy. On your 90D you are looking at an equivalent FL of nearly 1000mm. More clearly stated an AOV of a 960mm lens if compared to a FF camera. In short that's a lot of FL in anybodies book. As FL and/or magnification goes up so does all the bad things and at the very same rate. Mostly camera shake so a learning curve will be a thing. A monopod or tripod if possible will help. However, if BIF is your goal neither is of any help and really a hindrance.
