I recently picked up my R7 with the 18-150 kit lens and the 100-400. My primary application will be to try to come up to speed on birding/wildlife, but I want to fill out the lens lineup a bit for more general purpose and/or video use.I'll definitely be getting the EF-S 24mm, and probably the RF 50mm/1.8. I'm considering the RF 16mm but not immediately as I'm not really sure I need that FL in a prime.I'm also eyeing the Sigma 18-35 as a potential future purchase.So, that leaves an ultra-wide zoom. My original thought was the EF-S 10-18 since it's cheap and seems to be widely recommended. Browsing MPB though there are a whole bunch of wide EF-S zooms so I thought it would be worth gathering some opinions.Canon 10-18Canon 10-22Tamron 10-24 (2 different versions)Tokina 11-16, 11-20/2.8, 11-16IISigma 10-20/3.5, 10-20/3.5-4.6My thoughts: The Tokina 2.8 is the most expensive, but offers constant 2.8 which is valuable particularly for video but less so if I get the Sigma 18-35.  The Tamron 10-24 has the longest reach which gets solidly up into 'normal' range. The Canon 10-18 is tiny and seems to be well regarded and seems to generally be recommended above the 10-22.So, my question is: do any of these offer performance compelling enough to choose over the 10-18?Thanks for any feedback (and apologies for re-treading what is probably well covered ground, but surprisingly my search didn't really turn up much relating to R series)

Doing the exact same pondering myself. I have the rf 501.8 and ef-s 24 and like both. Though I am sad every time I put the adapter on the lovely 24 pancake and double its size and weight. Anyway, for what it is worth, I am a bit leery about the sigma 18-35. The Northrop’s say they have stopped recommending it for canon due to af issues. Perhaps someone with direct experience can comment.

Anyway, for what it is worth, I am a bit leery about the sigma 18-35. The Northrop’s say they have stopped recommending it for canon due to af issues. Perhaps someone with direct experience can comment.I have the 10-18 adapted on the R7 and works very well, I have not tried other alternatives mentioned.I also used the sigma 18-35 1.8 as my main lens on the R7 for almost a month and it worked great. Extremely sharp, great IQ, accurate and fast autofocus. I did not keep it due to its size/weight (front-heavy), and because I did not want to invest that much in an apsc lens, but I would recommend the combination if the focal lens range works for you.

I'd choose the EF-s 10-22. Seems like it's a notch above the 10-18.Kent

I have the R7 and EF-S 24mm 2.8 and it is a very good lens indeed. I used to have the EF-S 10-18 with a T7, and was great. I will probably pick up another one, since the IQ is outstanding.

Suggest used copy of the 10-18 - and then buy the RF-S 11-22 when canon ports it over from the excellent EFM lens.I have owned it before on the 7DII - and was just as good as the 10-22 in real life use.  The IS is nice too.I like my 11-22 on my M6II - and one reason I have kept the M6II

I have the Canon 10-22 and it is a nice range and works very well with my R7. However, especially combined with the required adapter, it is a relatively large and heavy package. Given that eventually Canon will likely make an RF version of the 11-22 EF-M lens, that will probably be a better choice. But when or if that will happen is a big question.

I use the 10-18 on my R7, alongside the 15-85 for general landscape/family and the 18-35 Sigma for low light. All great performers in terms of AF and image quality.

If you are going to use this lens for video then go with the EF-S 10-18mm STM. Its AF was designed to work very well for video use. The others you are considering will have issues due to their age and AF systems. Plus, this lens has very good IS which is likely better than the R7's IBIS when used on a non stabilized lens. The IS allows the IBIS in the R7 to be turned off and thus avoiding some of its issues with warping/warbling the video near the edges of the frame that has been an issue, in general, with Canon cameras. The EF-S 10-18mm also performs very well as a stills lens.

I loved the EF-s 10-22. Nevertheless I am pretty sure that sooner than later a comparable RF-s will come and that will be much more compact than adapted ones. So I would wait.

It's worth picking up a lens hood for it; I have the JJC LH-83L which works well.But yes, the R7/R10/R50 desperately need a native ultrawide, and a ported EF-M 11-22 would be perfect. Let's hope it comes soon.

I use the R and the 5Ds for higher quality and the stuff the M series can't do and APS-C for size, fun and pocketability. The M50 II is just too big for what I want from APS-C and the M6 II too expensive.

Yes, waiting PATIENTLY for the RF-S 11-22!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!R2
