Like any new lens, this will make it more expensive. If it adds a feature that's not found in other lenses, or is extremely rare, the...

Bob Howland replied to the thread A New Constant f/4 Aperture RF-S Zoom Coming.
I find that the concept of equivalence is not at all useful. When taking an image with an R7 and a Sigma 18-50, I don't calculate the...

Probably not, unfortunately.

Right or wrong it's how almost everyone thinks.Just go with it

The 180 rotation makes sense. that would indicate that the adapter created an intermediate focal plane and supports what my friend told...

Yeah, the integrated TC would seemingly add a bit to it. Definitely would make for some steep prices :cry:
It does seem like a...

Okay, today a White-lined Sphinx moth (aka hummingbird moth) visited my garden! Getting lots of visitors lately.

Saturday we had some crocuses appearing.
Today we had some yellow ones appearing, but not opening. I guess they wanted to stay warm...

It's technically possible to have a focal reducer that maintains the same lens mount and flange focal distance - there is a 0.7x focal...
Dragon replied to the thread Report: New Canon Super Telephoto Lenses Coming in May.
Not sure that even reducing optics would solve the problem. A friend of mine who worked for Canon for many years once pointed out to me...

No idea, but I'd expect that if the new 400mm and 600mm lenses have an integrated, switchable 1.4x TC (there were patents published on...

Do we expect these potential 400mm and 600mm big whites to be comparable in cost to their predecessors? I wish I were in that market...

Looking good! I like the filters.
Is a light mode/dark mode toggle possible?
Michael Clark replied to the thread Canon EOS R7 Mark II to Have Stacked 40MP Sensor?.
You can say I'm the Easter bunny. It doesn't make it true.
neuroanatomist replied to the thread Report: New Canon Super Telephoto Lenses Coming in May.
Whatever. Nikon has over 50 Z lenses ranging from 12-800mm. Canon has over 60 RF lenses ranging from 10-1200mm. Sony has more than both...

Doesn't matter how long it took for Nikon. They have 2 modern lenses with TC, Canon has 0. The last one is from 15 years ago. And while...
mawlki replied to the thread A New Constant f/4 Aperture RF-S Zoom Coming.
In a walk-around zoom i'd even prefer f4 over f2.8 (apsc-c) . A bigger aperture only will make things needlessly heavy and a prime like...

I currently have the RF 400 mm f2.8 lens and would strongly consider the upgraded version as long as the weight does not get any...

Thanks for the information. Always good to learn something new.

The advanced filters look really useful.

The EF to RF adapter is just a hollow tube because the RF mount is physically closer to the sensor than the EF mount (20mm vs 44mm) so...
neuroanatomist replied to the thread Report: New Canon Super Telephoto Lenses Coming in May.
Yes, it is a hollow tube...but not an extension tube. An extension tube is something that positions the lens such that the lens mount is...
John D P replied to the thread Report: New Canon Super Telephoto Lenses Coming in May.
I admit that I'm not an expert in optics and that I've never seen the optical design for the 200-400mm. I see your point, but I have 2...
