RF 800mm & 600mm F/11 First Of Their Kind, RF 400mm f/8 Might Follow Soon, Canon Exec

Canon Rf 600mm F/11

The Canon RF 800mm f/11 and RF 600mm f/11 are the first of their kind, more lenses will follow, and the first one might the RF 400mm f/8.

Mynavi.jp posted an interview with Canon developers. The discussed topic include the reasons for the RF 800mm f/11 and RF 600mm f/11 lenses, and some interesting things can be found.

Canon wanted to release lenses similar to the RF 800mm and 600mm f/11 also for the EF mount, but auto-focus was an issue:

In the days of manual focus film SLR cameras, there were many lenses such as the 500mm F8 reflex (mirror lens). However, when the viewfinder screen for focusing is split, it is difficult to see because the open value is as dark as F8, and in reality it was difficult to focus. This lens has a darker F11 opening value, but it can be said that it was born because of the EOS R, which can use high-speed and high-precision AF even at such an opening value.

Even more interesting is a statement by one of the developers clearly that the RF 800mm and RF 600mm f/11 are just the first of a series. The first lens to follow appears to be a RF 400mm f/8:

[…] Of course, 400mm is included when it comes to super-telephoto lenses, but first of all, 600mm and 800mm have a greater impact, and I think it’s a great pleasure to shoot things that I couldn’t shoot before, so the first one is in this lineup. Did. The 400mm will be as small as the 600mm and 800mm, and I think it will be an attractive lens. I would like to think positively whether it is better to make a series depending on how much the 600mm and 800mm echoes are.

The interview (machine translated) also discusses the RF 85mm f/2 Macro, and the EOS R5 and R6 from a general point of view.

Canon RF 800mm f/11 IS STM Review With Sample Photos

RF 800mm F/11 IS STM Review

Canon released two unique lenses with the Canon RF 800mm f/11 IS STM and RF 600mm f/11 IS STM. Here is a RF 800mm f/11 IS STM review.

Christopher Frost Photography posted their Canon RF 800mm f/11 IS STM review.

At a glance:

  • Super-telephoto prime is designed for use with full-frame Canon RF-mount mirrorless digital cameras
  • Fixed f/11 aperture contributes to the sleek and portable form factor as well as a balanced mixture of depth of field and sharpness
  • Gapless dual-layer diffractive optics contribute to a marked reduction in chromatic and spherical aberrations as well as benefit the design of a relatively compact and lightweight lens
  • Retractable/extendable design, with a locking lens barrel, offers an impressively compact form factor considering the super-telephoto design
  • An Optical Image Stabilizer helps to minimize the appearance of camera shake by up to four stops to better enable working in low-light conditions and with slower shutter speeds
  • STM stepping motor offers fast, quiet, smooth, and accurate autofocus performance that is ideal for video recording as well as still shooting
  • Configurable Control Ring can be used to adjust a variety of exposure settings, including aperture, ISO, and exposure compensation
  • Compatible with optional Extender RF 1.4x and Extender RF 2x teleconverters to further increase the effective focal length.

Also interesting: an interview with the engineers who made these unique lenses.

Canon RF 800mm f/11 & RF 600mm f/11 Review (the super-telephotos for us all)

Canon Rf 600mm F/11

Canon surprised quite a few people when they released the RF 800mm f/11 and RF 600mm f/11 lenses. I have yet to see a negative review.

Gordon Laing thoroughly looks at the Canon RF 800mm f/11 and RF 600mm f/11 lenses, the “super-telephotos for us all”, in his 18 minutes video review.

Also interesting: an interview with the engineers who made these lenses.

Canon Engineers Explain Why They Made The RF 800mm & 600mm Lenses (inspired by 1960’s 1000mm f/11)

In an interview, Canon engineers tell how it came Canon made the RF 800mm f/11 and RF 600mm f/11 lenses. And what inspired them.

In an interview with DC Watch, Canon engineers tell the reasons and challenges in designing the RF 800mm f/11 and RF 600mm f/11 lenses. It seems, a boyhood experience of one of the engineers was one of the reasons (machine translated):

Iezuka: I’m sorry about my boyhood story. At that time, I wanted to take a picture of a wild bird, Little Egret, but I couldn’t buy a super-telephoto lens because it was too expensive. I tried to make a telephoto lens with a close-up lens with a focal length of 400 mm, but it didn’t look good, and I wondered why it didn’t look so good.

I knew that there were many people who gave up what they wanted to shoot and the expressions they wanted to shoot because they couldn’t buy a super-telephoto lens and couldn’t carry it because it was big and heavy.

Canon already made a similar lens in 1960, the R 1000mm f/11:

Looking back, Canon’s first SLR camera system, the R mount (1959-), also had a “slender” super-telephoto lens like the 600mm / 800mm F11. The optical system is as simple as a telescope, the focusing is bellows, and the weight is as light as 2 kg.

The Canon R 1000 f/11

Why f/11?

Iezuka: Since the EOS R system can measure distances up to the maximum aperture of F22, I thought that the F value of the lens alone would be F11, considering the installation of a 2x extender. With F8, the lens becomes thicker, and with F16, it exceeds F22 when the 2x extender is attached. Around this time, the idea of ​​”Why don’t you eliminate the aperture unit for F11?”

I understood that there is a need to reduce the shutter speed further from F11 when considering panning at super telephoto, but control of the depth of field is less important at super telephoto, and it is low. The aperture unit was not installed because it leads to cost reduction and weight reduction.

Be sure to read the whole interview at DC Watch. More Canon RF 800mm and RF 600mm coverage is listed here.

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

RF 800mm F/11 IS STM Review

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.

They rated the lens “highly recommended” and gave it 4.5/5 stars. More Canon RF 800mm and RF 600mm coverage is listed here.
