Canon RF 24-105mm f/4-7.1 STM IS Review (good mechanical quality)

Canon RF 24-105mm F/4-7.1 IS STM Review

Here is a review of the inexpensive Canon RF 24-105mm f/4-7.1 STM IS lens for the EOS R system. It seems the mechanical quality is the only good thing they found.

Optical Limits tested the Canon RF 24-105mm f/4-7.1 STM IS, and their verdict isn’t very positive:

In absolute terms, it’s clearly a sub-standard lens. Its native characteristics range from good to downright terrible. The miserable vignetting and distortions have to be seen to be believed. Conversely, the resolution is actually pretty decent – which is a bit of a pity because you just won’t use this lens without auto-correction.

That’s being said – it is highly unlikely that you invest thousands into a high-megapixel camera and then just a few hundred on a cheap kit zoom lens. The pixel-level sharpness increases towards lower sensor resolutions and the vast majority of users have cameras featuring 20 to 30 megapixels (as of the time of this review). Within this context, the Canon RF 24-105mm f/4-7.1 STM IS makes much more sense. The 24mm setting will still not be perfect here but it’s certainly usable.

[…] the mechanical quality of the lens is pretty good for a kit zoom lens. The used materials are of high quality. The (extending-)inner lens tube is a bit wobbly though and this seems to be a theme across Canon consumer-grade Canon lenses.

Mainstream Media Suggests Canon EOS R3 Might Have 45MP

Canon Eos R3 Price

We know plenty about the upcoming Canon EOS R3, with the notable exception of price, announcement date, and imaging sensor resolution. A mainstream media article backs our rumor about a 45MP sensor.

Discussing the rumored specifications of the Nikon Z9, Techradar reports an allegedly solid rumor suggesting the Nikon Z9 might have a 45MP imaging sensor doing up to 30fps. Techradar writes:

Canon hasn’t yet officially confirmed the resolution of the Canon EOS R3, its equivalent mirrorless camera for pro sports photographers, but rumors have strongly suggested that it’ll also be a 45MP camera. We do already officially know that R3 will be able to shoot 30fps bursts and oversampled 4K video.

Other sources have suggested a 30MP sensor is going to be featured on the EOS R3. Time will tell.

Latest intel suggests an EOS R3 announcement in Fall is likely. Expect the EOS R3 to get eventually announced in September 2021. In the meantime you might check some product images, or have a look at an interview with a Canon exec. Here are are the known and rumored EOS R3 specification in one list:

  • 45MP or 30.1MP backside illuminated image sensor (resolution is not confirmed yet)
  • Multi-Controller & Smart Controller
  • Vari-Angle Touch Screen
  • NEW accessory shoe
  • Wifi 5GHz
  • High speed 30fps electronic shutter with AF/AE tracking + RAW shooting at this speed
  • AF down to -7.0 EV
  • 8 Stops Coordinated Control IS with Optical IS and In-Body IS
  • 4K Canon Log3​
  • Oversampling 4K
  • Internal RAW video
  • Inclusion of cars and motorbikes in AF tracking technology
  • RAW internal movie recording
  • Speedlite shooting with electronic shutter
  • The same weather sealing as the EOS-1D series
  • LP-E19 Battery
  • Dual card slot SD & CFExpress

All our EOS R3 coverage is listed here, product images are here and here. There has been some discussion about who makes the imaging sensor of the EOS R3. You can get notified when the Canon EOS R3 will be available for preorder.
