could it be that the video files are saved on the sd card and not the cfe card

Why do the customer organisations remain silent ?
Brexit may have triggered such a development, but can't be used to explain or justify this flagrant abuse.
No wonder Panamoz & co. flourish!

I don't imagine replacing the RF rubber seal is any more difficult than the EF seals. I don't have an RF lens. On the EF lenses remove the mount screws, lift the mount a bit and work the old seal off, reverse the process to install the new seal. I have replaced a few over the years, always do when I replace a mount. I replaced the mounts on my 300/2.8 IS before I sold it and on my 500/4 IS (before they become impossilbe to get). The last EF seals I bought from Canon last year were $16.74 each.

Beautiful shots. I especially like the first one.

Many years ago, I had the privilege of visiting the Zeiss facility in Jena, Germany. Although Zeiss-branded ILC lenses are primarily made by Cosina in Japan, the founder of the company, Carl Zeiss, started making microscopes in Jena in the mid-1800s. When we discuss things here like the Abbe limit or Schott glass, I am reminded that Ernst Abbe and Otto Schott worked for Zeiss in the late 1800s. Zeiss' research microscopes are still made in Jena, and it was amazing to see the production process up close.

Abbe was the partner of Zeiss. According to camera wiki, he founded the Zeiss Foundation that was responsible for the photographic optics. He appears to have been a fine man as well as scientist, and was against discrimination: "Ernst Abbe's founding principle from 1896 that world-view or ideological or confessional convictions were not allowed to be considered in hiring employees". Unfortunately, Zeiss threw in its lot with the Nazis in 1933 and used forced labour during the war. http://camera-wiki.org/wiki/Carl_Zeiss
Their official history glosses over the use of forced labour https://www.zeiss.com/content/dam/c...the_companys_history_of_zeiss-at_a_glance.pdf but it appears to have been pretty bad https://ymcinema.com/2019/10/17/the-dark-side-of-zeiss/ as well as other incidents https://slate.com/technology/2014/0...ecuted-inventor-rudolf-straubel-of-zeiss.html

Might want to also consider backpacks by ThinkTank Photo or Gura Gear.

+1 to ThinkTank. I've got two of their backpacks and a Retrospective 30 messenger bag from them. The Retro 30 can store a surprising amount of gear and be stored under the seat.

Ehhh, not necessarily, but do you think R&D is free? Novel tech costs what it does NOT primarily due to manufacturing (though that’s of course one factor because yields may initially be low, defect ratio may be high, processes not yet optimized, fraction of manual labor high as production lines not yet automated, and small quantities not benefiting from exonomies of scale…) but due to the need to amortize all the research and development costs incurred before a single finished product was made! Economics 101. Expert scientists and engineers don’t work for free.

Click to expand...

The other considerations are market size and what costs the market will bear. For example, R&D costs for cystic fibrosis (CF) treatment drugs are actually lower than for heart failure (HF) prevention drugs (the latter need multiple Phase 3 trials with thousands of patients), but CF drugs list for hundreds of thousands per year while HF drugs list for a few thousand per year. CF is a small market of very sick people who desperately need meds, HF is a large market of people with high risk but who otherwise often feel pretty healthy and may not even think they need treatment.

Pulling my hair out waiting for this one - anybody seen availability info anywhere yet?

Click to expand...

It is only available in China as far as I can tell.

scyrene said:

I would quibble the wording, as the quality is the same, you've just discarded the edges of the image. But clearly it's a much lower resolution image. Fwiw I use crop mode a lot but I tend only to view on my phone and share downscaled for social media so even 7MP is more than enough for my purposes.

Click to expand...

A sharp 7mpx close up shot usually gives excellent feather detail. I also don’t understand the difference between cropping in camera and in post.

I am just starting to play with it.

The Sigma 14/1.8 is E mount only (maybe EF in the future??) but the Sigma 20/1.4 is EF so can be adapted for R mount.
Are these the 2 lenses that you are referring to?

Click to expand...

The Sigma 14mm f1.8 Art (Sigma barcode number: Canon EF Mount 00-85126-45054-0) is avaible in EF mount so can be used on a RF camera. It is the Sigma 14mm f1.4 that is only available in the L mount and Sony E mount.

Nice design and great work! I’m in the polymer industry and suggest you consider something a little stronger impact wise than ABS however. It isn’t bad persay but I would be concerned if it got a shock of some sort. Once ABS begins to fail it can fail rather dramatically. Polycarbonate would do the trick and be plenty strong….if you can 3d print it.

Macro lenses are intentionally designed to be optimized for close distances. It shouldn't be surprising that means compromise in performance at infinity.

Click to expand...

Depends on what you mean by compromise. Soft corners, for instance, I cannot accept for landscapes. The corners at infinity of my EF 180 are mushy, no matter which aperture I use, even if "corner focused".
A slight drop of performance is usually the case with most macro lenses, and acceptable. What I need is kind of a universal lens, since I hate changing lenses when hiking in the mountains.
I must say I've been spoiled by my leica M and R macro lenses (M 4/90, R 2,8/60, R Apo 2,8/100). All three are tack-sharp even in the corners. This is why, after having heard so much praise about the RF 100 L, I hope it will produce excellent results at infinity too!
The only trouble with the Leica 100 Apo being the lack of AF, otherwise...

AF on my Sigma 180 2.8 is much better on the R6 than the 5D IV.

@Kiton why do you hate the adapters? EF 40mm with adapter stills very compact.

Click to expand...

when I first got my R5 I had a 28-70 2.0 on one and a 70-200 2.8 on the the other with adapters, and really did not like the feel more than anything else.

Today I have an assignment with some politicians and will bring the 40 on the R6.2 and see how it feels, it seems to be alomst the same size as the 50 1.8.

neuroanatomist said:

The sensor in the R8 and R6II has a 14.5 ms readout speed, slightly faster than the R5. Personally, I still use EFCS so I get the full bit depth in my RAW images (the R3 is the only Canon body so far that outputs 14-bit RAW with full electronic shutter).

Click to expand...

In my experience, the R5 in EFCS mode is much worse at tracking erratically moving birds (like hunting swallows) than in full ES mode. Maybe that's less relevant with hummingbirds.
