Does anyone know of a reliable all-in-one reader for CFexpress-B, SD, and MicroSD cards? Browsing through Amazon, it looks like any reader that has CFexpress does not offer a micro SD slot, and vice versa.

I've been using this CFexpress + SD reader for about a year using a MicroSD to SD card adapter. Transfer speeds seem to be generally decent for CFexp and SD, but other than that, I'm not at all happy with it. The SD card is somewhat loose and has disconnected on me a few times during a transfer. Also, the reader will occasionally get hot to the point where you can't hold the back of your hand against it for more than a few seconds at a time. The whole thing makes me uneasy. I've swapped it out for a replacement about a month into owning and the second reader is no different.

I appreciate any suggestions or product recommendations.

Seems, there are rumors, the upcoming Sony A9 Mark III has an global shutter. (from sony alpha rumors)
Canon, please, do the same on the R5....

Canon announced the RF 24-105mm f/2.8L IS USM Z last week with a lot of fanfare. With that lens came two PowerZoom accessories, the PZ-E2 and PZ-E2B. The latter utilizes the 20pin port with allows it to work with compatible Canon cinema and broadcast accessories. Over the weekend we were told that the RF 24-105mm

Hello people,

I own a Canon RF 70-200 f4 L that has a button that locks zoom at 70mm. I just love this feature. Bought a RF 15-35 2.8 L and the same doesn't happen, it's always rotating the zoom and moving.

Why Canon just don't do this by rule? It's an fantastic feature to have!

Cheers!

According to the Canon MTF charts the RF 800mm f/11 and RF 100-500mm + 1.4xTC @ 700mm are nearly identical. This means the 800mm should outresolve the 700mm because of the extra 100mm. I find this with my copies. Others have reported the opposite. It could be that I have a poorer copy of the 1.4x (and I have never been that happy with it) and a good copy of the 800/11. Others might have vice versa. So, I am interested in others experiences.

Received the lens two days ago. Hectic weekend with two kids, and my wife working until nearly dark. And this new lens has learning curves for capture and for processing.

You'll see three versions of the same shot of the tub, a tub which is not round but oval. (This one's distortion really surprised me.) The file names are descriptive, but, just for clarity, "LRC no correction" shows how the image looked when opened in Lightroom Classic. "LRC w correction" shows a modified RF 14-35mm f/4 lens-correction applied to the 10-22mm. The modification was to move the distortion slider on the Profile tab to 112, plus some vignetting mitigation. Finally, "DPP default" is how the image looks when opened in DPP.

To better show the vignetting when opened in LRC without corrections, I've included two versions of the clump of bamboo.

All were shot at 10mm, various camera settings.

It should only get better from here, right?

Hello,

Anyone has some EF 400 mm f5.6L vs RF 100-500 4.5-7.1 L photo bokeh samples?

I really don't care about IS, zoom, etc. I just care about bokeh because 400mm f5.6L is already an awesome lens but I find bokeh a little busy. Is RF lens at 400-500 the same? I would LOVE to see the differences to know if I should upgrade or not (it's expensive!!).

The only reason to me is if bokeh is more creamy.

Any help?

Why are high end lenses constant aperture? Isn't the max aperture a limitation of the long end due to the size of the lens entrance pupil? Couldn't these lenses have even bigger apertures at the wide end with no increase in size?

What I'm wondering is: what would the physical difference between a 70-200 f2.8 and a hypothetical 70-200 f2.0-2.8 be? Shouldn't those come out at the same physical size? Or say a 24-105 f4 vs a hypothetical 24-105 f2.8-4?

Perhaps someone in physics and lens design has a good answer.

I chose to put this as an opinion because I’m not a lawyer, and while my background is in engineering, we are talking about a rather convoluted subject matter. That really can only be answered accurately by lawyers familiar with the legislation. We won’t know for sure until after December 28th, but in my opinion,

There’s been a lot of excitement with the new Canon RF 24-105 F2.8L. I find it great when Canon flexes its vast engineering and optical expertise and creates something truly unique. It’s been a great month or so for Canon and well, for me too writing about it. There’s been a lot of previews released

The Canon RF 24-105 F2.8L jumped into the limelight with the latest announcement. This lens may not be for you. It’s big, it’s heavy, and pricey and Canon really wants this lens primarily for the cinema cameras. From all reports it’s not fully parfocal (which means the focus will change as you zoom), but it’s

Double Rainbow this afternoon in a short break between showers.

I don't really see the point of f/2.8 trinity any more.

1) We don't need it for viewfinder brightness.

2) We don't need it for autofocus. (In the 90s and even I think the EOS-1Ds MkI MkII MkIII, only the center AF point worked at smaller then f/2.8.)

3) We don't need it to avoid grain/noise or to freeze motion on moving subjects. (Current sensors are fantastically low-noise at high ISO.)

4) We don't need it to shoot still subjects that would otherwise require a tripod (50/1.8 on R5 shoots about as well at 1/2 sec as at any speed above 1/30)

5) We don't need it to make subjects pop from backgrounds. (It used to be that focus was never great, lenses weren't so high resolution, film was grainy, exposures were blurred by camera shake, and so even the SUBJECT was pretty blurry. Because of those factors, we didn't use images in big sizes. In order to make the background visibly yet blurrier at this low print size, f/2.8 sometimes helped to make the subject stand out. But now, we prepare every shot even for our personal social media to be 15" (38cm) wide. The sensors are practically noiseless. The AF is utterly nailed to the subject eyes. Lenses can do 50lp/mm or better at very high contrast. Sensors are noise-free up to ISO 4000+. IBIS saves us with camera shake. The subject is absolutely clear as a bell and even f/4 (wider shots) or 72mm aperture (tele) gives us more pop at these large image sizes than we ever got at f/2.8 in the old days.

------------

In reaction to the new 24-105/2.8, and the nice 15-300mm f/2.8 trinity it creates: I do get the utility of 24-105. For me I've been shooting 24-105/4 instead of 24-70/2.8 pretty much exclusively for 15 years now, despite shooting 24-70/2.8s since they were 28-70s... 24-105 is a a great shooting range. I even used the RF24-105 almost exclusively on my R despite having a half-dozen EF lenses in the cupboard.

I just don't see the need for f/2.8 for it though.

The EF MkI 24-105/4 was a good size but soft. The EF MkII was bigger and better IQ. I'd summarize the RF MkI as being the EF MkI size with EF MkII image quality. I'd like to see them make a higher image quality RF MkII, even if substantially bigger and more expensive, and I'd buy it instantly.

I do love the big apertures too like the 135/1.8 and would order a 35/1.0 or 35/1.2 instantly, for special projects, but I don't need f-stop bigger than f/4 or aperture greater than 72mm in general. f/4 and 72mm do everything I need to. For me the big question is: if you need more than f/4, and I agree such cases arise, how can f/2.8 be enough? If I really want to blur backgrounds or something, then I want not f/2.8 but f/1.4 or bigger.

Thursday is a big day for Canon shooters, as Canon will be announcing 3 new lenses and shipping the recently announced RF 10-20mm f/4L IS STM. We have confirmed some information about the Canon RF 200-800mm f/6.3-9 IS USM. Yes, it is USM and not STM, which is great and makes a lot of sense

Kakakumag.com has published their review of the Canon RF 10-20mm f/4L IS STM that was announced earlier this month. The review is in Japanese, but Google Translate works just fine.

Hi, all. As the title says, I'm looking for a 600mm lens for some wildlife videography here in Japan. something that doesn't break the bank as I'm just dipping my toes in this field and will probably just use it to shoot videos for a YouTube channel, photos for social media, etc.

I spend so much of my free time watching wildlife around Japan and I run an arts promotion company with a video production arm so I thought it made sense to combine the two. I'll probably end up deeply regretting taking my work home with me, so to speak, but that's a problem for tomorrow.

I'm thinking of using it with a spare Canon C70 (s35 sensor) and an EF to RF speed booster for that extra stop of light as the EF 600/4 is well out of the budget for this personal project. I might also use it with an R5 for stills.

I was looking at the Sigma 150-600mm f/5-6.3 DG OS HSM Sports Lens for Canon EF, but I can't seem to find any in stock or second hand.

Any other recommendations or experience with the Sigma? Should I be looking for something different? Thanks in advance!
