Canon EOS R7 and 18-150 lens

Hello

I am wondering what the pro shooters think of the lens that presently comes with the Canon R7? The 18-150 lens that is that is not a pro lens. Canon says it is a very good lens. And that might be, but does it qualify as a lens for the pro's?

Any experience out there with that lens? I have a lens that I would like to use with it if I get the camera. I have a 70 to 300 pro ef lens, or I could use my ef 24-105 pro lens. and use the other on my mark 6.

It is interesting that Canon chose to send this camera out only with this lens, and says that the camera by itself is not ready to come out yet. From Canon's perspective I am sure it is a good business decision to be able to sell that lens with the camera, and a perfectly legit business practice to do it. From the consumers perspective that may be a little different. I think either way of looking at it is fine, it is what it is. Just a little unfortunate for some consumers. But any perspective on the value of this lens, and how well it operates would be appreciated.

Thanks in advance

It is a very good lens even though it is not an "L" lens, as is the RF 100-400 when used on the R7, since as a crop sensor it only used the middle of the image where the RF 100-400 is at its best. Remember also the RF-S 18-150 was designed for the R7/R10 crop sensor cameras along with the RF-S 18-45. Canon's first RF-S lenses, so you expect them to make them a cut above normal, as it is never a good thing to start a new series of lenses with a mediocre product.

Look here at an image I took with the 18-150 this morning: https://www.uglyhedgehog.com/t-756409-1.html

Thanks, robertjerl. This is very good information. I hope I can get this camera soon. The picture you directed me to was excellent.

This lens is optically identical to the EF version, meaning that the advantages of the shorter flange of the R mount are not being utilized. I do not have this lens, but I have done some research on it and it is clear that in no way is this lens optically comparable to shorter zooms or primes. Sharpness leaves something to be desired, especially in the corners at the wide and tele ends. In addition lateral chromatic aberration is quite strong at the wide end, and reappears at the tele end. Coma is also quite evident. The build quality of the lens is consumer grade, and not weather sealed. I would not take it out for rugged use.

That being said, for consumer use, it will provide decent images overall. The deficiencies will not really be apparent in small prints and on the web.

Here's a pro's review: https://www.kenrockwell.com/canon/eos-r/lenses/18-150mm.htm

After a series of images, his summary:

I love this little R7 and 18-150mm IS STM combination. It's small enough to carry everywhere, and captures everything I can see, no tripod required. The two are a hugely capable system in a tiny package, especially the lens. Bravo!

In today's digital mirrorless world, a "pro" lens is more likely to be a constant 'wide' aperture and a rugged (more metal) body. For a 'pro' lens, at least from Canon, the lens will come with a hood too. Image quality is likely to be indistinguishable from lenses without all that metal (weight).

The pictures shown in the article are in my opinion, outstanding. I certainly would like this camera and lens. Of course, that still means I have a third lens and I do not like changing lenses due to the possibility of dust on the sensor. However, with automatic sensor cleaning that does not seem to be as much of a problem anymore.

I do like those pictures.

Thanks, CHG_CANON

hmmm, it looks like the r7, body only, is available at best buy now, but not B&H photo. I will have to do some more checking on this.

There has never been an "EF" or "EF-S" 18-150mm lens.

There have been three EF-S 18-135mm lenses that are completely different designs.

The RF-S 18-150mm actually is an adaptation of the EF-M 18-150mm lens. They use the same optical formula (which is different from the EF-S 18-135mm USM or STM's). Since both are mirrorless systems, there is only 2mm difference in the flange focal distance of the R-series and M-series cameras. The EF-M mount flange focal distance is 18mm while the newer RF-mount's is 20mm. So it is a rather simple and very sensible adaptation that fully utilizes the short flange focal distance of the mirrorless camera.

I'm hoping that Canon will adapt more of the EF-M lenses to the RF-S. While very few lenses were ever made for the M-series cameras, there are some excellent lenses in that older system that would be ideal on an R10 or R7. In particular the EF-M 11-22mm, EF-M 22mm f/2, EF-M 28mm f/3.5 Macro and EF-M 32mm f/1.4 all would be great on the new cameras. I was surprised that Canon chose to make a new RF-S 18-45mm instead of simply adapting the compact EF-M 15-45mm.

It is too bad that Canon has shut down 3rd party RF-mount lens development, because there are some superb 3rd party lenses for the M-series cameras (as well as for Sony, Nikon, Fuji and Oly/Panasonic). Sigma makes truly excellent 16mm f/1.4, 30mm f/1.4 and 56mm f/1.4. Viltrox makes very good and affordable 23mm f/1.4, 33mm f/1.4 and 56mm f/1.4.

Yes, the RF 18-150mm is a "consumer grade" lens. Versatile, moderately compact, light weight. Very good for that type of lens. It's ertainly not an "L" in build or image quality. But it's also not priced like an L-series.

The R7 is in stock now at B&H, both "body only" or with the RF-S 18-150mm. With the kit, the lens costs $100 less than if it were bought separately.

Lots of interesting information.

Since I wrote this several things have happened that will change my perspective on things. It would be nice to have the R7, even nicer the R5, but the R5 is very expensive. I may be willing to trade in some of my old equipment though to get the R7. Well, it depends on lots of factors, including the opportunity to get around to various places with really nice landscapes and such. One thing I really like about the R7 and R5 is the image stabilization. I don't however, have a lot of info as to how much the image stabilization actually works for better image quality, or just makes sure the image has a horizon that is straight.
