Cooke announces the new SP3 Full Frame Cine Lens Set

No matter how much filmmaking continues to innovate and progress, we always have an appreciation for nostalgia. Contemporary film projects that use older, classic lenses is a never-ending trend, but that does not come without its own unique issues. Now, with the release of the new SP3 Full Frame Cine Lenses, Cooke invites you to partake

Snails, mussels and other molluscs

As I thought, those animals also deserve a dedicated thread but couldn't find one, I opened up this one.
Post your photos of snails, mussels and other molluscs here and enjoy this sometimes a bit slippery topic ;)

Here is a wonderfully posing Roman snail (helix pomatia), aka. escargot.
Last photo with a bit too much back focus, as the AF was more interested in the shell
R6m2@500mm, f/16m 1/500, ISO2000-6400
The high shutter speed was not because it was a racing snail :ROFLMAO:, but because on that day I was focussed on birds and dragonflies

CFexpress 4.0 Announced!

CFexpress 4.0 has been announced and the only real changes are in the NVME spec that has been bumped to 1.4, to give greater efficiency, though the NVME spec used in CFexpress is still behind the latest (2.X) used by SSDs, due to the feature upgrades having no real use with rewriteable flash media used by cameras and other such devices. No camera bodies are expected to incorporate it until 2025, at the earliest, as the existing card and device host controller designs have to be upgraded and tested together, before they can be certified and brought to market. As intended, the new cards and cameras will be backwards compatible with the current cards and cameras that are using the current CFexpress standard.

Canon Speedlite EL-10 rumored for later this year [CR2]

Canon’s new Speedlite rollout for the EOS R generation has been a bit messy. The first Speedlite announced for the lineup was the entry-level EL-100. Which felt like a bit like a half-baked attempt to address the line. There’s nothing wrong with it for $149, but the missing rear display always irks us. The second

MF Fisheye Lens Recommendations: TTArtisan or 7Artisans?

Hi,

I was curious if anyone has tried one or both of these lenses in the RF mount?

TTArtisans 11mm 2.8 Fisheye

7Artisans 10mm 2.8 Fisheye

I am looking for a casual fisheye lens for fun. The pricing on the two lenses is close enough that it’s not a deciding factor, but the smaller size/weight of the TTArtisans is compelling. Something easy to throw in the bag just in case, but not a huge pain to lug around on a hike.

I am curious to see if anyone has used one or both of the lenses, and what your feedback is. I already have wide angle rectilinear lenses, so this is just for fun and would be to keep the fisheye look. Ease of De-fishing is not important for this decision. It will be my first MF lens so I am hoping to have fun with it without breaking the bank… or the back.

Anything feedback you can share is greatly appreciated, thanks!

Canon Patent Application: Fast Focusing Prime lenses

In this patent application, Japan Patent Application 2023-120952 Canon discusses developing lenses for video, surveillance, and stills photography that have very quick autofocus. The method they use for this is reducing the weight of the focus group to allow for quicker focus. There are a few embodiments that look cool – but the back-focus distance

RF100-300 mm f2.8 with 2x TC used for a week in Alaska

Dear Everyone

I am returning from a trip to Alaska where I used the RF 100-300 mm f2.8 lens with the 2x TC as the prImary lens for my wildlife photography of bears, sea otters, seals and some birds. Overall I am very impressed with the lens on the R3 camera. Focusing was still very quick and pictures were sharp by my standards.

I used the combo on land both handheld and with a tripod. I also used the combo when sea kayaking. I was overall very impressed and found the 200-600 mm range very useful.

All photos shown below and the vast majority during the trip were taken wide open at f5.6 with the 2x TC with the Canon R3. Photos are processed in DXO PhotoLab 6 with only mild sharpening (Unsharpen Mask I=75 Radius =0.5) applied. Focal lengths range from 300-600 mm, but most photos I took were within the 450-600 mm range.

Canon Patent Application: Miniaturization of built-in teleconverter

In this Japan Patent Application, JP 2023-118490, Canon is investigating creating smaller built in teleconverters for use in lenses that we would normally not expect to see a teleconverter installed in. The idea of this patent application is to make the mechanism and the sliding out of the optical elements that make up the teleconverter

Which Canon DSLR works best for manually-focused EF lenses through the optical viewfinder?

I have some high-quality manually-focus Canon Cine EF lenses. They have digital contacts on the back (so they relay information to the camera), but they have no motors for focus or aperture.

I'm also a manual-focus shooter generally, going back to my film days, when the microprism at the center of the optical viewfinder worked great for me. In fact, I don't think I've ever shot an auto-focused photo in my life that I can recall, at least not one that I actually used for anything (I've of course tested autofocus before). I'm funny that way.

But as I'm reading about various Canon DSLRs, I'm seeing that they have varying support for manual focus through the OVF.

First, many of the modern ones don't have swappable focusing screens, and you can't see the true depth-of-field for your lens at large apertures (the extra bright default focusing screens eliminate off-angle light). In the 5D line, you have to go back to the Mark II to swap in a true-matte screen that lets you see the true DOF. And this matte screen is readily available still. If you go into the 1D line, up to the 1Dx Mark II (but not Mark III), you get a whole range of possible focusing screens, including micro-prism and split-prism screens. But none of these seem to be available anywhere.

Then there's the issue of whether the AF points could be used easily to confirm sharp focus in manual mode.

Seems like this worked well in the 5D Mark II, but not the 5D Mark III and later, as described here:


Maybe in the Mark II, as you focused back and forth, all 9 of the focus points would become active in turn as they each passed through being in focus.

Likewise on the 1D series---it seems like things got worse with the 1Dx, as described here:


Perhaps you could pick a point in the 1DS Mark III, and then that point would light up when it was in focus. But in the 1DX, the point itself doesn't light up, but instead some other light in the corner of the OVF lights up.

Of course, this could potentially be overcome in the 1DX and 1DX Mark II, if you could get micro- or split-prism focusing screens.

But even so, it seems like for manually focusing using AF points to confirm focus, the 5D Mark II might be the best of the bunch?

And I'm not even sure how helpful the AF points are for manual focus anyway. Perhaps they allow too much wiggle-room around a truly sharp focus.

But reading about these in manuals only gets me so far, and most reviewers don't spend a lot of time talking about this issue.

Does anyone have experience manually focusing with these different Canon DSLR models? Is there one that really stands out in terms of the best manual-focus experience?

(And no, I don't want to use the live view... the whole point of a DSLR, for me, is the optical viewfinder.)

RF 100-400mm magnification and focus breathing with distance

A bit of geek from me about the RF 100-400mm. I do a lot of semi-macro photographing of dragonflies and butterflies with it at 1 to 3m (3-10') and wanted to know what the magnification is at those distances and for amusement how the focal length drops as you get closer to the target. Here is a plot of my measurements of the magnification at close distances and the calculated focal length at each distance. I used the read out of the distance from target to sensor from the exif data - because that is what I know from all the images I take. You can calculate the size of your object from the second graph of magnification vs 1/distance using the equation in the plot (for the R7 I used).

At the minimum focus distance of 950mm at the focal length setting of 400mm, the magnification is 0.43, close to the 0.41 claimed by Canon. The calculated focal length at this distance is 200mm. By 3.5m distance, the focal breathing has improved and the f is 340mm.

The EF 100-400mm II, in comparison, has at 970mm a magnification of 0.31x and f calculated to be 178mm. The RF 100-500mm at 970mm has 0.33x wuth a calculated f of 224mm.
