Have a couple of them and they have preformed real well in both my R6MkIII and R5 MkII for half the price of OEM. And the USB charging has worked great when I'm out and about, plug them into the cars USB and the charge fairly quick.

I've used a variety of Blackmagics over the years. Under controlled conditions, with good lighting, they make a very nice image. I personally find their form factor though to be less-than-desirable for most field situations, and in uncontrolled settings the image can sometimes be not great.

I did some testing. I will post the review soon

Neither was the weight. I tried to pick one up many years ago and had a shock. As a matter of interest, how do you handle this 3.7kg lens?

Carrying it around the sidelines attached to my monopod (I had to upgrade the tilt head from a Manfrotto 234 to an Oben VH-A30 to support the lens) and a gripped 7D Mark II attached to the lens was like carrying a bowling ball on the end of a stick. I typically held the monopod with my left hand with the lens facing rearward resting over my left shoulder while moving around. I had two other bodies on a dual harness with a 70-200/2.8 on one and either a 24-70/2.8 or 24-105/4 on the other.

Heya

I'm looking for a couple of people to beta test a new site feature. A return of an old one I guess.

You can PM me on the forum.

I think 2-3 people is enough, I don't need more than that telling me everything I have done wrong.

You put the lens in a vise.

Just joking around....

And...crank it as hard/tight as possible?!

No. The latest version is 1.9.0 from 2024. Given that the R6 is now two models out of date, I would not expect any more firmware updates (and if there is one, it will be to fix a glaring problem, not to add any features).

rip this never happened I need it so bad.

Well, I shoot cRAW as well.
The CRAW file is 34 mb. The DNG uncompressed is 163 mb. The compressed DNG file is 31 mb !
Albeit, with one test. Don't have the time now to do more tests.

Click to expand...

I have processed 11100 CRAW files from my EOS R7 with PureRaw 6 and DeepPRIME XD3, exporting as compressed DNG! Results:

• CRAW: 197.72GB (17.8MB/file on average)
• Compressed DNG output: 190.63GB (17.2MB/file on average)
• For comparison, out-of-camera JPEG cumulative size: 108.16GB (AdobeRGB, non-HDR; 9.7MB/file on average)

So my numbers are very similar to your findings, in that the compressed DNG output is slightly smaller than the CRAW file on average. My settings were "luminance" 40%, "force details" 5%. Just for reference, processing took around 21 hours.

Hope this helps!

My JJC lens hood arrived today

I have to say, I think JJC is building them better and better.

This is my fourth or fifth JJC lens hood and it’s the best so far. The plastic is thicker than ever, and it has the same textured finish as the petal-shaped version for the RF 35mm f/1.8 (similar to some Canon EF lenses).

It’s really good, I can see why they’ve been increasing their prices.

Friendly reminder: Canon’s RF lens hoods do not have velvet on the inside either.

Keep in mind that the 'crop factor' does not just apply to focal length. Image noise is inversely proportional to sensor size. So while the 'brighter' f/2.8 lens on the iPhone seems like it would be better than the f/4 lens on your R6, in fact your iPhone video will have about the same amount of noise as if you were shooting the scene at f/10 on your R6.

Thanks!

This is a big improvement. Once they added the 3:2 and 1:1 crops to EOS VR Utility, it was really annoying to be having to use the 16:9 or 8:9 guides on the camera to just guess at what your shot's framing was going to be.

I really need to get my hands on these special lenses to know how they work.

Canon has released a minor firmware update for the EOS R50. Canon has released a firmware update for the EOS R7 as well. Firmware v1.5.0 for the R50 is a minor update that adds improvements when using the RF-S7.8mm F4 STM DUAL along with stability improvements. This firmware update will make it to other global […]

See full article...

Using a very complicated yet powerful algorithm called "average", I can state that an intermediate lens between the RF 85mm F/1.2 and the RF 135mm F/1.8 could be a RF 110mm F/1.6.
Or F/1.5.

This apparently weird focal length and aperture would make sense IMO, considering that
1) it could weight less than a 100mm F/1.4, and that
2) Canon RF lenses ofter offer something different from old EF lenses and from other brands' ones.

But any "RF 100-105mm F/1.something" would be interesting.

I enjoyed that 40mm lens. It made my Hexanon 52mm f/1.8 feel slightly claustrophobic.
While irrational, I'd like to see Canon make an RF f/1.8 40mm. I can't bring myself to get the 2.8.

I'm still kicking myself for not picking up an EF 40mm f/2.8 STM pancake from the Canon USA refurb store before that lens was discontinued. It's one of those things I always meant to do but never quite got around to it. I do use the EF 35mm f/2 IS quite a bit, so I really have no need for the 40mm.

I am currently using this lens with the R10 and waiting for the R7M2. For info, photos from yesterday:

But I waited half a year for the lens.

mimbu said:

AFAIK there are no FF AF mirrorless lenses with mechanically linked manual focus. Everything is fly by wire.

Click to expand...

That does seem to be the trend.

mimbu said:

With many of the modern linear AF systems I don't think it's possible (or maybe it's just impractical) to have mechanically linked MF.

Click to expand...

I doubt it, or the EF lenses wouldn't work.

I think the loss of mechanical linking is more about giving the platform greater control over computer-controlled AF for very fast or erratic subjects, such as athletes and bats (as in the mammal). I strongly suspect that the people who tend to talk directly to Canon are more in these situations, and they can reasonably purchase (personally or via a company) multiple big white lenses, or beasts like the 28-70.

And the fact that EF lenses still reasonably exist. So if you're weird like me and like that kind of feel or universal MTF then that stockpile satisfies the need, in one way of thinking.

I just re-read your statement and I think I replied after misreading what you wrote. I agree, it probably is impractical. In which case if mechanical linking were reintroduced it might well need to be with older EF technology such as ring USM.

mimbu said:

This does bother me because we saw what happened with some of the older Canon lenses that were also entirely electronic for focusing. The 200/1.8L. The 50/1L. Many more. Once parts availability ends, the lens is completely useless if the AF motor dies.

Click to expand...

Bingo.

---

I think that if the following were achieved by Canon then mechanical linking could die a full death for my purpose and feel:

1. Universal FTM focus during one-short and servo, regardless of lens (including older RF lenses)
2. No need to push AF-on or shutter button
3. Tactile feedback in the focus ring with resistance and placement stickiness (use a quality, modern L EF lens to understand this)
4. No damage potential if the focus ring is spun with or without power
5. No need for menu option or camera switch to engage, or default to engaged
6. Identical approach to FTM on all Canon R cameras going forward — again, no on-body switches on some but not on others, etc.

My EF USM lenses all achieve: 1, 2, 3, 4, 5, & 6. My 40mm STM is focus by wire.

I understand that many L series RF lenses support: 4, and 1 can now be achieved for most using firmware updates for the lens and sometimes the camera. Probably all except 3 and 6 can be solved with firmware. 3 would probably require some hardware, and 6 is more of a camera design thing.

Everyone upset about interpolation is gonna flip when they found out what “debayering” is.

As we all know, lens design is about tradeoffs. If y’all want to pay for and carry around all the extra glass elements that these “optically perfect” lenses would require, be my guest. But I welcome smaller, lighter, fewer glass element lenses using digital rather than optical corrections as long as the performance is up to snuff. And I think any rigorous lens testing methodology shows that most of the L-series lenses have the performance we all expect, regardless of the correction type used.

Get the photo - video switch on the right side, not the wrong, as on R5ii

Do you think this update will introduce a global shutter or/and computational imaging

Click to expand...

No.

Follow-up:

So, I the took the lens for an assignment, on Sunday afternoon, but saw nothing really useful in it (to me, that is), so I packed it up nicely on Monday morning, and sent it away in the afternoon.

It's a really nice lens, the form factor and working mechanics are awesome, but it doesn't really add much to my work, is just excessively wide.

Thanks for brainstorming @neuroanatomist

For either double grip pro bodies, do you think this update will introduce a global shutter or/and computational imaging
