Hello everyone, I currently use a Canon Rebel T7 and am looking to upgrade to a mirrorless system for bird photography, which is a serious hobby of mine. I've narrowed my options to the Canon EOS R7 and the EOS R10, both with the RF 18-150mm lens.

Currently, there's approximately a 300-400 euro price difference between the two. I can afford the additional cost of the R7, but if I choose the R10, I could purchase the R10 with the lens and the RF 100-400mm. With the R7, I would have to wait to get the amazing 100-400.

I understand the R7 has IBIS, a higher resolution sensor and sealing. Will these features make a significant difference for bird photography as a hobbyist? Does anyone here have experience with these cameras for bird photography? I do a lot of landscape and nature photography as well.

I would greatly appreciate your help!

I currently have 5Dmk4 and some EF glass (35 f1.4, 24-105, 2 70-200s f2.8 IS and f4 IS).

I am considering picking up a travel camera, preferably one usable for birding or at least non-zoo wildlife. I have looked at the currently available options, and so far R7 and R10 seem the best candidates. For me the killer feature in both would be basically bit lesser weight, and also ability to use USB charging (bringing along charger is yet more weight and bulk with the 5D).

R7 has bit more MP, dual cards, and IBIS, but is heavier. Larger battery size seems like the biggest gain for me though.

R10 on the other hand is really lightweight, and would be probably lovely for travel.

Currently I'm considering just getting just RF-EF adapter and using my L old lenses (or 5Dm4) if weight isn't problem, and e.g. RF 18-150 for single-lens travel use-case (15-85 EF-S with adapter would be possibly also good, although I suspect RF 18-150 is more versatile).

I'm currently leaning towards R10 just due to the lesser weight; is there some reason why I should reconsider and get R7 instead? And is RF 18-150 'fine'? Reviews seem to indicate it is good enough.

Since the release of both camera's I've been looking to get rid of my backup body (the RP) and add a crop sensor to the collection. Specifically for wildlife, to get more use out of my Tamron 150-600 telephoto lens. I recently picked up wildlife photography and enjoying it a lot, however not sure if it's something I'm fully committed on yet.

My main reason to go for either of these 2 bodies is their insane AI autofocus and tracking combined with the newest technology, DIGIC X and sensor. But here is where I'm stuck.

The R10 is basically the R7 but in a cheaper body with a bit less options but for me I wonder if the R7 is worth the extra price bump. This is why:

• I never had IBIS and I don't think I really need it

• I never use any camera in pouring rain or wet conditions

• I never do video on my camera

• I don't need 2 SD card slots (in 8 years I've had no issues using one slot)

• battery life of both camera's is already better than what I own now and I always make it though the day with this.

• I prefer the wheel and button layout of the R10 because it's more familiar.

So basically my only reason to go for the R7 would be to have a more future proof body, which is more robust, has a bigger battery and more megapixels. But I really wonder if the megapixels is something to go for or not. The price difference here is €1.700 (R7) vs €900 (R10). You can get quite a cool EF or RF lens for that difference.

So What do you think I should do? Get a more future proof body for almost double the money or try out the R10 which ticks most of the boxes for me and settle with less good specs.

For some context, I currently use a Canon SL3 for purely amateur bird photography. I'm moderately happy with its capabilities, however I find it doesn't do well for low light scenarios or capturing fast-moving objects. I also need a longer lense as I've found my 55-250mm doesn't give me the reach I need.

So, rather than simply getting new glass, I thought It would be best to just get a whole new kit. Admittedly, most of my research has been with Canon since I'm more familiar with their products, and I think I've settled on upgrading to an R10 As much as I like the price of the R50, it sounds like the difference is significant enough that i should be looking at the R10.

I don't have a fixed budget, but for the body I'd like to stick around 1000$ CAD, and I've been able to find a used R10 for just over that. If going with canon mirorrless, I'd be pairing the camera with the RF 100-400mm f5.6-8 IS USM lens (around 750$ CAD).

Now the question is: is there another camera/lens combo from another brand that would be priced similarly but may perform better for my needs?

I appreciate any input.

My question is, I understand most people would suggest the R7 for birding. But why do I see so many pro photographers using the R5 when out birding? I see multiple photographers on YouTube like Simon d'Entremont and Duade Paton using the R5 when out photographing birds. If the R7 is the better choice for birding and wildlife, why are they using a full frame? Thanks for any clarification.
