Bryan at The-Digital-Picture has completed his review of the Canon RF-S 18-45mm F4.5-6.3 IS STM, the brand new “kit” lens for the EOS R7 and EOS R10.
Bryan has also completed his review of the Canon RF-S 18-150mm f/3.5-6.3 IS STM.
From the review of the Canon RF-S 18-45mm F4.5-6.3 IS STM
This lens is tiny, measuring only 1.7″ (44.3mm) in length and mostly 2.5″ (62.4mm) in width.
The 4.6 oz (130g) weight is barely noticeable.
While the focal length range is not especially long, it has the most-used focal lengths included.
This lens produces decent image quality and physically performs well. It even has image stabilization that coordinates with IBIS.
Everyone will love that the price tag is lower than any other Canon RF mount zoom lens. Professional photographers will love the low financial risk of treating this lens as disposable in scenarios dangerous to the lens.
While the Canon RF-S 18-45mm F4.5-6.3 IS STM Lens is a fine “Only” lens for a lightweight, low-cost kit, it is also a nice option to have available in a high-end kit. Read the full review
Can I talk to these professional photographers real quick?
Canon always threats APS-C as a necessary evil or something. Like they are not even trying to make something unique.
Don't bother with this lens because it's clear that Canon didn't either.
After the R7/R10: “Canon, why did you give us this cheap, crappy kit lens? Why?!?”
Next up: “Please, Canon, give us an affordable UWA zoom for RF-S!”
Some people never learn.
Cheaper lens should not mean the narrowest and darkest focal length range ever. Even the ultra cheap EF-M 15-45 or EF-S kit zooms had better parameters. Will the next iteration be something like 35-70mm F5.6-F8 equivalent like compact cameras had 15 years ago?
I don't think anyone is asking for a 12-100mm F2 for $500 but something at least matching what other manufacturers are offering, like Nikon's 16-50 (again, same size and weight and price as Canon's 18-45) or Fuji's 15-45.
Or at least don't go backwards. At the moment Canon is offering an inferior lens (compared to 15-45) for more money.
I agree that 18-45mm f/slow is a pretty crappy spec for a kit lens. I think Canon took the cheap and easy path for it. Compare the EF-M 18-45 (left) to the RF-S 18-45:
The RF-S version is a similar design, using smaller elements but lacking the rear diverging correction group. Unlike the RF-S 18-150 which simply used the EF-M 18-150 optics in a new barrel, that could not be done with the EF-M 15-45 design because the 2mm longer flange distance of the RF mount means a 15mm lens needs to be a retrofocal design (like the RF 16/2.8), and that would have resulted in a higher cost than Canon wanted.
As a cheapskate landscape and macro EF-M shooter, I just can't see any reason for me to switch to RF-S right now. I'll admit the bodies are great for action, wildlife, and birds. They make great sense for an EF-S shooter who is happy with their current lenses and ok with using an adapter. But I think everybody else is being left out in the cold. Canon has a long hill to climb on RF-S lenses, and their first steps don't look very promising to me.
The sensors on the r7/r10 dont perform any better than EFM either! What a crapshow. + They have blocked 3rd parties from making AF lenses...what a travesty. If you are not already invested in canon, its just not a good time to get in.
They made great RF FF bodies and lenses, then its been downhill ever since with uninspired, boring, lackluster designs. Old canon is back!!!(?)
I think the sensors are fine. The R7 sensor is actually slightly better than 90D's or M6 sensor but also there is not much image quality improvement that can be done with the current technology. Sure, a stacked sensor with fast readout would have been nice in the R7 but that's probably too much to ask from Canon.
The M mount could have been the perfect travel system but that seems dead now. The RF-S not started too well in lens department. Probably the same story will repeat again: Canon will release a cheap and slow wide angle and maybe 1 or 2 APS-C primes and that's it. Don't expect anything revolutionary or even inspiring. Even Sony is treating their APS-C system much better, having a few very good quality zooms and just released 3 wide angle lenses at the same time. Something unimaginable from Canon.
