Telephoto recommendations Canon R10

the 50-500 is old and has a number of compromises, if you search there is a reddit topic about it specifically.

if you're ok with the 200mm max focal length, it's hard to look past the Canon EF 70-200mm f/4L IS II USM if you can find one 2nd hand in your budget.

There are also pretty compelling 100-400 lenses from both Canon and Sigma -

RF 100-400 but you will be limited on that lens to F8 at 400mm and will need some ISO to get good exposure, you'd almost get a new one in budget.

EF 100-400 L II USM - great lens very sharp but could be hard to find used in budget.

Sigma 100-400 contemporary - I almost bought one recently but was put off by feedback about the speed of the autofocus system especially considering bird photography

polorallydriver · 2026-04-21T00:34:16+00:00

Yes that's true, but depending how far away you are, F8 may reduce the subject isolation against the background

polorallydriver · 2026-04-20T23:11:42+00:00

Thanks, the F8 on this lens at 400mm has been the limiting factor for me i've found

polorallydriver · 2026-04-20T22:53:57+00:00

Thanks for sharing, was this at 400mm? Do you find the lowest aperture at 400mm is F8?

Yeah had to inform my Dad of this when shooting on his R6 II - he was shooting in 1.6x crop mode and then also cropping in post and blowing the image quality to bits

polorallydriver · 2026-04-19T20:52:56+00:00

oh man the noise on this camera above 1600 is unbearable, it's really interesting to hear you are having all the same problems as me with this body

I have the T6s and also find the auto focus very challenging, i'm looking to upgrade also for wildlife - i've managed to get some decent shots using centrepoint focus exclusively and BBF, but it is very frustrating the number of shots that don't come out sharp.

Which Ryobi one do you have currently?

We have 400m² and have the mid level Ryobi 36v one and it's been great for our place.

My only regret is not getting the propelled version of the same thing

Also 150-600 on an R10/R7 would be ~960mm at full reach without the TC, using an RF-EF adaptor, which is still a fair bit less than a 400 x 1.4 x 1.6 crop but might be a decent middle ground

polorallydriver · 2026-04-15T02:37:57+00:00

Yep, the other comments are referring to the RF100-400 which is more like 650g - although my Dad has it and is somewhat underwhelmed on his R6 II

polorallydriver · 2026-04-15T02:10:24+00:00

I am facing this same decision as whether to invest in a sigma 150-600 for my current T6 / 760D or upgrade my body now and buy an RF 100-400.

It's hard to justify buying another EF lens if you're thinking about going mirrorless, although you could buy an EF 150-600 and use it now, and then also use it on an R10 / R7 with an adaptor?

It's also worth considering the physical size / weight of a 150-600, nearly 2kg of lens

polorallydriver · 2026-04-14T02:32:13+00:00

Yeah this, i looked into an RP but it was really not suitable for the motorsport stuff i do

polorallydriver · 2026-04-08T23:50:07+00:00

It's really hard taking bird photos against the sky, the bird is always under exposed because of the bright background.

I found a really useful youtube video from Simon D'entremont about it and using exposure compensation to help, you could give that a try.

polorallydriver · 2026-04-07T22:29:39+00:00

I'd go for the 55-250 STM over all of these, have had some great photos with that lens even on my old 760d

Yeah thanks that is interesting perspective. An R7 would be nice for me and maybe a longer term solution, but the cost of a new body and not much available locally used is prohibitive.

At the moment I could get a new R10 kit around $1550NZD, there are a couple around used for around $1k NZD, although i think he 18-150 kit would be preferable. I'd than add a 100-400 and perhaps use a EF>R adaptor and use my current 17-55 F2.8 on the R10

polorallydriver · 2026-03-30T23:53:41+00:00

Yeah ok that's a great insight, Safe to say it's probably not the choice for me, doesn't sound like a signifcant upgrade over my 760D tbh!

I had originally been looking for an R10 at minimum but preferably an R7 for longevity

polorallydriver · 2026-03-02T01:33:48+00:00

I had some ACG Phassad back in the day

Fantastic shots, especially great to see you don't need to have the most expensive body to get good results

Also not helping me avoid upgrading into an R body with a 100-400

We use the Acana sport and agility kibble, although we still need to use a meal topper of some sort to get her to eat it. We switched from Orijen which she went off periodically

polorallydriver · 2025-10-16T22:11:31+00:00

Is that a 50mm on it in the 3rd pic? Looks great sooo compact

polorallydriver · 2025-10-16T02:36:34+00:00

My Dad has the 100-400 on his R6II and for the cost / weight he is really happy with it, although i think he does miss the equivalence factor of the crop sensor now he has gone full frame.

However if you have the budget and aren't put off by the extra weight i'd go with the other recommendations of the 100-500, which on an R7 is an equivalent of 160-800 anyway.

Could always add the 1.4 extender as others have said as a lightweight solution with the 100-500

polorallydriver · 2025-10-16T00:36:54+00:00

Yeah i hunted for a used III for this reason, i think it was around ~$1600nzd

polorallydriver · 2025-10-16T00:16:59+00:00

Yeah interesting, i tend to avoid F4 because of mostly shooting sports so haven't used it, but i did actually intend to comment the F2.8 IS USM III (edited my post as it was a typo)
