Canon R7 Sigma 18-50mm 2.8 DC DN First Impression.

Paired with the R7. This tiny lens is pure joy to use. With decent light you can produce quality photos. I turned the control ring to control F-stops. On APSC, you don't want too Push more than 6.3. Yes there a limitation on this lens. No built in IS. No problem with the R7. I wish sigma would have made the wide end 10mm. The R7 gets very noisy in very low light. If you are thinking of buying the little lens. You won't be disappointed. Yes I have the R5 also. Both are a joy to craft pictures. RJ

Got this lens when it came out last summer. I'm so happy with it that I got their 56mm f/1.4 prime when it came out in December and just ordered their 10-18mm f/2.8. All are small and light and the R7's IBIS makes OIS unnecessary - it even lets me hand-hold my EF 200mm f/2.8L II with the EF 1.4 telextender at unbelievably low shutter speeds. My only lens with OIS at this point is the RF 85mm f/2 Macro IS - another gem.

This lens plus the R7, has given Me so much joy crafting pictures with such ease. I also use a R5 plus 24-105 combo. Love both.but R5 is much heavier beast to tote around, Also you can use the 24-105 F4 on the R7

Just got the Sigma 10-18mm f/2.8 DC DN C RF Fit. (I don't know why, but Canon has never licensed the -S variations of their lens mounts! "DC" in a Sigma's name means it's for APS-C crop sensors. Since it uses the standard RF mount, it won't automatically trigger crop mode on a full-frame R camera.)

This lens gets me the 16mm angle of view my old RF 16mm f/2.8 had on the R6 II, and is a third the weight (and two thirds the length) of the Tokina EF 11-20mm f/2.8 I experimented with last year. Instead, it's about the same size and weight as the Sigma 18-50mm f/2.8 DC DN C RF Fit that lives on my R7.

With their 56mm f/1.4 DC DN C RF Fit (also about the same size) for low light situations, I now have half of their initial offering of RF lenses and have overcome the two major shortcomings of APS-C: low light and narrow angle of view.

The R7's IBIS lets me have small light lenses and a much more portable kit.

One tip about these Sigma RF lenses: they all follow the approach of Canon's smaller RF primes of sharing a ring between Control and Focus modes - but without a switch on the lens or any marking on the lens that it's anything other than a focus ring (that's controlled through the camera's menu). I recommend setting the menus (1) to make such rings act as manual focus rings, (2) turn on "full time manual focus," and be done with it.

I'd like to start a campaign to get DxO to support the Sigma RF lenses. While all six of them are supported on the Sony, Fujifilm and EOS-M cameras, only the 18-50mm is supported on EOS R - and that only after I got Sigma to send them one to test.

Since the R7 and the M6 II (on which they're all supported by DxO) share the same 32.5 mp resolution, I don't see why DxO is dragging its feet on this, other than fear of Canon dominance.

Please submit a request to DxO to support the other Sigmas on the R7 (the 10-18 f/2.8 and the four f/1.4 primes: 16mm, 23mm, 30mm and 56mm) at DxO Supported Cameras.

It's gonna take a lot of requests.

I also got the 18-50 2.8 for my canon r7
Nice lense, lightweight combination as well.

One thing though, the lense hood/cao doesn’t lock on the lense, no resistance in final position
So it basically just rotates back easily and falls down.
Anyone else experience this and what could this be?
I looke d at the interior of the cap and noted 3 screws. Maybe I can adjust the play?

Cheers

I suspect that you hadn't pushed the hood far enough onto the lens to mate with the locking mechanism before turning it.

The hood is fully engaged in the locking mechanism, it just doesn’t lock, it just stops hard at the end with no resistance so it just rotates back easily.

Sorry, my mistake. I just had to put some more pressure to rotate the hood fully 90 degrees and it clicked in . sorted
