Sigma 150-600mm f/5-6.3 DG OS HSM
Reddit take
AI summary of the Reddit excerpts below — not a quote
The Sigma 150-600mm f/5-6.3 DG OS HSM (Contemporary) is a popular, budget-friendly super-telephoto lens favored for wildlife and aviation photography. While it is praised for its cost-effectiveness and impressive reach, it is frequently described as heavy and physically taxing for long-distance use. Opinion is notably split regarding its performance on modern mirrorless systems; while many users still achieve sharp results, a significant number of reports highlight frustrating autofocus issues, including hunting and pulsing, when the lens is adapted to Canon RF-mount bodies.
Pros
- Highly cost-effective super-telephoto reach
- Capable of producing sharp wildlife and bird images
- Excellent for airshows and aviation photography
- Solid entry-level option for those needing 600mm on a budget
Cons
- Heavy and bulky (approx. 3.2kg), making it difficult for hiking
- Image quality can be soft at the long (600mm) end
- Frequent autofocus hunting and 'pulsing' issues on Canon mirrorless bodies
- Focus breathing can make it unreliable for tracking subjects on newer cameras
Caveats
- Performance is significantly more reliable on native DSLRs than on adapted mirrorless systems
- The 150mm minimum focal length can be too tight for large subjects (like elephants) at close range
- Softness on APS-C sensors may negate the benefit of the extra reach compared to sharper 400mm lenses
Best for
- Budget-conscious wildlife and bird photographers
- Aviation and airshow enthusiasts
- Users on Canon DSLR systems (EF mount)
Avoid if
- You use a Canon R-series mirrorless body and require flawless AF tracking
- Weight is a primary concern for your photography style
- You have the budget for the Canon EF 100-400mm II or RF 100-500mm

Have a look at a 100-400 (Tamron and Sigma have some decently priced ones, the Canon 100-400 mII is pricier but great) or a Sigma 150-600C.
A Sigma 150-600C would work for that.
I have seen the reviews and read all the echoing posts regarding the focus breathing issues of the 150-600 on a Canon mirrorless. I have also seen MOUNTAINS of good quality sharp images with that lens on a Canon mirrorless (wildlife/birds)
I run the Sigma 150-600 and getting decently clean shots for my use cases
Sigma has a 150-600mm that is popular, but to me the 150-600mm is right on the edge of something you can hand hold. ... Sigma 150-600mm is one of the most cost effective long lens available. Still tremendously capable.
Traded a Sigma 150-600 that was really soft when fully extended and didn't perform well once the light starts to fade.
a Sigma/Tamron 150-600 or 100-400 for wildlife... That Sigma on mirrorless bodies is sketchy
For the long end, you may consider Sigma's 150-600. It is one of the more affordable options when it reach is your necessity.
Picked up a sigma 150-600 yesterday, loving it but need a tripod recommendation. The DeWalt one isn’t quite secure enough, this lens is very heavy.
I have a massive Sigma 150-600 for wildlife. But it's way too heavy and zoomed in on my R7 (240mm).
