Gordon Laing of CameraLabs has published his review of the Sigma 18-50mm f/2.8 DN DC C on the Canon EOS R7 and compares it to the Canon RF-S 18-45mm f/4.5-6.3 IS STM kit zoom.

To me, it´s kind of weird that the product images show the lens attached to the R5. Wouldn't it make more sense to use the R7/10/ 50?
Constant F2.8 aperture, 300g and weather sealing sounds great :)
From the looks of it, the only downside is that it doesn't have a control ring. Since the R50 only has one dial (if I remember correctly) this actually could be an issue for me one day...
For me, nothing in the R system beats the R8+28mm for compactness and performance. The R7 is too big, the R10 is too expensive for what it delivers, I hate the EVF in the *50 bodies and I really want a touchscreen, so the R100 is out as well.
Nah, the guy they used for the example images just happened to have an R5 and they used his beat up camera for the images. (nothing wrong with a beat up camera)
I know the \"DC\" designation on Sigma lenses means \"crop sensor\", and that having both \"RF-S\" and \"DC\" is redundant, but that\'s extra knowledge that buyers need to have.
Including both the \"DC\" and \"DN\" would enable more knowledgeable buyers to realise this is the Canon mount version of the same lens available for other mounts.
Even Sigma doesn't want to get anywhere near a R100 for promo purposes.
Sigma uses DC for all of them, on any platform - it's consistent.
Mount with dust and splash resistant structure
The lens mount incorporates rubber sealing to protect the mount from dust and water drops.By comparison, the Canon RF-S 18-150 has:
- Same size
- Same weight
- 3x the zoom range
- Image stabilization
The obvious advantage of the Sigma is speed and constant aperture; the Canon starts at f/3.5 and is already at 5.6 at 50mm, a 2-stop difference from the Sigma.
I'll be curious to see comparisons between the two lenses to see what the IQ differences are, if any, and if they are really perceptible in the real world.
I like the direction Panasonic is taking with video and LUTs, the inability to quickly share a clog3 video is very annoying.
I had a number of nice short clips of red squirrels being cute when I was in a hide this weekend and wanted to send them to my kids. The only time where you have ViewAssist applying the LUT is during capture, so I had to video the back LCD with my phone…
I need clog to correct my mistakes, I’m not a video person :)
It's reasonable to expect Canon users to have some level of knowledge of Canon nomenclature, which is RF means full frame, RF-S means APS-C.
It's less reasonable to expect them to know Sigma's nomenclature, especially when it runs counter to the established Canon system. Sigma is already adding RF to the designation, so that's not consistent, as you put it, across the entire output, since it's specific to their Csnon-fit lenses, so why not make it RF-S (and leave the DC, or DG as appropriate)?
(Sorry about any back-dlashes; I'm writing this on a phone.)
every single vendor isn't going to change their naming scheme to match every OEM.
I'm pretty sure Canon users are smart enough to figure this out.
though i have to admit, them showing it on an R5 certainly can make some confused.
