Canon RF 100-500mm f/4.5-7.1L IS Review (incredibly capable, incredibly expensive)

Canon RF 100-500mm F/4.5-7.1L IS Review
View Post

Here is a Canon RF 100-500mm f/4.5-7.1L IS review. The RF 100-500mm f/4.5-7.1L IS is seems to be another optical masterpiece by Canon, albeit an expensive one.

Key features:

  • RF-Mount Lens/Full-Frame Format
  • Aperture Range: f/4.5-7.1 to f/32-54
  • One Super UD Element, Six UD Elements
  • Dual Nano USM AF System

Photography Blog reviewed the . They called it an “incredibly capable but also incredibly expensive telephoto zoom lens“. Here are some excerpts from their conclusion:

Auto-focusing proved to be both satisfyingly quick and very quiet, with the ability to manually override it and focus manually if required proving a nice touch.

The very capable image stabilisation system goes some way to making up for the relatively slow maximum apertures.

[…]

Image quality is outstanding. Both center and edge sharpness are excellent even when shooting wide open throughout the zoom range, chromatic aberrations are very well controlled, and bokeh is impressive despite the slowish maximum apertures.

[…]

The new Canon RF 100-500mm F4.5-7.1L IS USM improves on its popular DSLR predecessor in a lot of ways – it’s sharper across the frame and throughout the zoom range, has a more effective image stabilisation system, is lighter and more compact, offers faster autofocusing, features a fully removable tripod collar and a customisable control ring, and extends further to offer 100mm extra reach.

Canon Might Release Two Versions Of The RF 35mm f/1.2L (one having Defocus Smoothing)

Rf 35mm F/1.2L
View Post

Not the first time the Canon RF 35mm f/1.2L lens is rumored. Now, it seems Canon might release two versions of it.

Canon might release a DS version (Defocus Smoothing) of the RF 35mm f/1.2L. They did the same with the RF 85mm f/1.2L, a truly amazing lens.

Both versions of the RF 35mm f/1.2L might get released in the first half of 2021. A patent describing the optical formulas for the RF 35m f/1.2L has been spotted in the past and it is quite likely it refers to the upcoming lens.

Stay tuned.

The EOS R5 is highly regarded as a stills camera. In particular, the EOS R5 autofocus system seems to be huge leap forwards.

Canon EOS R1 And Two “big white” RF Telephoto Lenses Coming In 2021?

Canon Eos R1
View Post

Here is a new EOS R rumor, and it’s about the Canon EOS R1 and new telephoto lenses for the RF mount.

The rumor suggests Canon will release two “big white” telephoto lenses along with the C Canon EOS R1 somewhere in Q2 2021. Please note that “R1” is a moniker created by the community, not an official Canon naming.

No idea so far if one the big white telephoto lenses is the rumored RF 500mm f/2.8L. A RF 300mm f/2.8L IS lens is also a possible candidate. In any case it fits into Canon’s strategy to gradually broaden the professional RF lenses lineup.

The EOS R1 is supposedly the EOS R camera equivalent to the EOS-1D X lineup. Honestly, we have some doubts Canon might release such a camera in 2021 but everything is possible. It’s a while it’s rumored, and we are sure it is coming.

Stay tuned.

Canon RF 800mm f/11 IS STM Review (highly recommended)

RF 800mm F/11 IS STM Review
View Post

Whaaaat? a f/11 lens with 800m? Kidding? Read this Canon RF 800mm f/11 IS STM review and you might get surprised.

At a glance:

  • RF-Mount Lens/Full-Frame Format
  • Fixed f/11 Aperture
  • Retractable, Locking Lens Barrel
  • Gapless Dual-Layer Diffractive Optics

The RF 800mm seems to be the world’s lightest 800mm telephoto lens. That’s possibile because of the fixed f/11 setting. Photography Blog posted their Canon RF 800mm f/11 IS STM review. From their conclusion:

[…] there’s no getting away from that fixed f/11 aperture which limits its use to either bright conditions or high ISO speeds (or sometimes both), the lack of any kind of weather-sealing at all may well put off more hard-core users, the 6m minimum focusing distance is a little restrictive, the tripod mount can’t be rotated from landscape to portrait position, there could be some question marks over the long-term durability of the retractable design, and the essential lens hood is unfortunately an expensive optional accessory.

All in all, though, the Canon RF 800mm F11 IS STM is a refreshingly brave attempt to make an otherwise expensive branch of photography more accessible, both in terms of cost and portability – there simply aren’t any other 800mm lenses that are as inexpensive, compact and crucially as good as this one. Bravo to Canon for thinking out of the box.

Sigma Explains Operating Conditions Of Sigma EF Lenses On The Canon EOS R5

Sigma 30mm F/1.4 Canon Eos R
View Post

What motivated Sigma to release this advisory, have there been issues with EF mount lenses on the Canon EOS R5?

However, Sigma “verified the operation with our SIGMA GLOBAL VISION (SGV) interchangeable lenses (Contemporary, Art, and Sports lines) for Canon EF mounts used on the“ Canon EOS R5” with Canon’s mount adapter “EF-EOS R Series”, and confirmed that there were no problems with general operations such as AE, AF, and image stabilization”. Good to know.

Sigma advisory:

Operating conditions of SIGMA’s lenses for Canon EF mount with the Canon EOS R5

Thank you for purchasing and using our products.

We would like to share the results of our investigation regarding the operation of SIGMA’s lenses for Canon EF mount, when used on the Canon EOS R5.

We have verified the operation with our SIGMA GLOBAL VISION (SGV) interchangeable lenses (Contemporary, Art, and Sports lines) for Canon EF mounts used on the“ Canon EOS R5” with Canon’s mount adapter “EF-EOS R Series”, and confirmed that there were no problems with general operations such as AE, AF, and image stabilization.

Please note the following points when using our products.

1.　For SGV interchangeable lenses released before 2017* , it is necessary that the lens firmware is updated to Ver.2.00 or later.
* The release year can be confirmed by the edition number (A017, C015, etc.) engraved on the lens barrel.

Please refer to the following page for details of the lens firmware.
https://www.sigma-global.com/en/download/lenses/firmware/

2.　After setting the Digital Lens Optimizer to [OFF], set the “Peripheral Illumination Correction”, “Chromatic Aberration Correction”, and “Distortion Correction” of the “Lens Aberration Correction” function to  [ON] to achieve the appropriate corrections in accordance with the optical characteristics of each lens.

3.　AF can be used within the area of approximately 80% of the height and 80% of the width of the sensor surface.

4.　For lenses without an OS (Optical Stabilizer) mechanism, the in-camera image stabilization can not be used when the Full-time MF setting is set to “Full- time MF ON” via SIGMA Optimization Pro. When using in-camera image stabilization, please set the Full-time MF setting to “Full- time MF OFF”.
* The default Full- time MF setting is “Full- time MF OFF”.

5. 　Image stabilization does not work optimally with interchangeable lenses which are not from the Contemporary, Art or Sports line. Please turn off the camera’s Image stabilization setting, or turn off the OS switch for lenses equipped with an OS (Optical Stabilizer) mechanism when using.

6.　For interchangeable lenses which are not from the Contemporary, Art or Sports lines, using MF is recommended, since it may be difficult to achieve sufficient focusing speed and accuracy when AF is used.
