Michael Clark replied to the thread Is Ring-Type USM on the Way Out?.
USM was THE technology which tilted the majority of professional photographers shooting 135 format to switch from Nikon to Canon in the...
Michael Clark replied to the thread Is Ring-Type USM on the Way Out?.
It'd be interesting to see if the EF 70-200mm f/2.8 L IS II and III would do better in this regard, considering Roger Cicala's claim...
Michael Clark replied to the thread Is Ring-Type USM on the Way Out?.
Meh, the EF 70-200mm f/2.8 L IS II was introduced in 2010, the EF 70-200mm f/2.8 L IS III came in 2018. Granted it was a minimal...
Michael Clark replied to the thread Is Ring-Type USM on the Way Out?.
Well, except for the the RF 75-300mm f/4.5-5.6 II, then III, which will be identical to the RF 75-300mm f/4.5-5.6 other than with...

Regen translates to "rain". I cannot tell you though why that's the translation... I assume they not only come out during rain ;-)...
Michael Clark replied to the thread A New Constant f/4 Aperture RF-S Zoom Coming.
That he is, but on this point he is also correct.
Michael Clark replied to the thread A New Constant f/4 Aperture RF-S Zoom Coming.
Except it's not unless you enlarge images from all sensors by the same factor and your FF images are thus 1.6X larger than your APS-C...

Things that make you go, "Hmmmm?"
Michael Clark replied to the thread A New Constant f/4 Aperture RF-S Zoom Coming.
At narrow angles of view (i.e. telephoto lenses) the EP and the front element are pretty much the same size, give or take 10% or less...
Michael Clark replied to the thread A New Constant f/4 Aperture RF-S Zoom Coming.
Weather resistance is pretty easy to do fairly cheaply. I've used the same two OP/TECH rain covers dozens of times over the past 15+...
Michael Clark replied to the thread A New Constant f/4 Aperture RF-S Zoom Coming.
I've had an EF 17-40mm f/4 L since around 2011. It also likes to flare and ghost if there are bright specular highlights, such as...
Michael Clark replied to the thread A New Constant f/4 Aperture RF-S Zoom Coming.
Perhaps that's why Canon quit making f/2.8 APS-C zoom lenses?
Michael Clark replied to the thread A New Constant f/4 Aperture RF-S Zoom Coming.
That's because the entrance pupil for wide angle lenses is not at the front, it's generally behind the aperture diaphragm. If a 20mm f/4...

Promises, promises...
Michael Clark replied to the thread A New Constant f/4 Aperture RF-S Zoom Coming.
Differences in magnification ratio to get the same viewing size from disparately sized sensors also affect Depth of Field, but not in...
Michael Clark replied to the thread RF 24-105 f4-7.1 vs RF 24-70 f2.8 in daylight.
The constant aperture f/2.8 obviously also gives you the option to shoot at wider apertures in brighter light if your camera can shorten...
Michael Clark replied to the thread Report: New Canon Super Telephoto Lenses Coming in May.
Except while all of this focusing and refocusing is going on the subject is often moving erratically and changing the distance between...
Michael Clark replied to the thread Report: New Canon Super Telephoto Lenses Coming in May.
It seems to me that with MILCs the issue is usually how accurately the lens can move compared to how much the camera told the lens to...
Dragon replied to the thread Report: New Canon Super Telephoto Lenses Coming in May.
That all makes perfect sense but doesn't address the idea that the system should be able to tweak the goal on the fly since it has...

That sounds like the original 7D in AI Servo mode.

To make the things little bit more complicated:D: Semipalmated plover (Charadrius semipalmatus). Non breeding plumage.

neuroanatomist replied to the thread CF Express 4.0 memory cards.
Depends on what you mean by supported. CFe v4 work fine, but Canon bodies only support v2 speeds. I have a set of Prograde v4 cards (3 x...
