500 mm lens

Is Canon going to be making a 500 mm lens like the new Nikon 500mm PF?  I have Nikon firends that are raving about the sharpness and light features of this new product.  I'm still carryng a heavy huge lens around with my 1DX2.

We have no idea. The closest is the EF 400 DO.

I suspect that any 500mm DO will be an RF mount.

"Is Canon going to be making a 500 mm lens like the new Nikon..."

I have to agree, there will not likely be any new EF lens made.   Just like FD, EF time has passed like it or not. I did not like it then and I don't like it now. The difference between now and back then is, I don't have to buy RF mount lenses.

Nailed it!

Canon just released some DO 600 and 800(!) mm lenses for RF!

From Ken Rockwell:

"These two are the most innovative products announced today. Many of you, especially those of you who remember DSLRs whose finders would go dark and couldn't focus with slow lenses, may not realize how incredibly well the EOS-R system works with slow lenses and even stacked teleconverters.

These two lenses are tiny for their focal lengths. They use Fresnel lenses (a.k.a. DO, Diffractive Optics) and even collapse for storage! Canon thought out of the box and gave birders and others two long lenses that will work brilliantly on the EOS-R system that never could have been done on SLRs or DSLRs. Bravo, Canon!"

Whoopee super slow lenses.

Which doesn't matter on an R.

If you follow the link, KR had a 100-400 f/4.5 - f/5.6, an EF converter, a 2X *and* a 1.4X teleconverter, and focused easily at f/12.6 or so.

They will focus but they push the ISO higher and cannot provide the shallow DoF of the faster glass. 

It does fit the mirrorless concept of making everything lighter and less expensive.  It will be a very good lens for people who don't need the low light capabilities of faster glass and who will be happy to trade off cost and weight, others will continue to use EF L series prime glass and an adapter when fast glass is needed.

"Which doesn't matter on an R."

It ALWAYS matters, slow glass is a problem unless you are just a hobbyist or amateur.

[kvbarkley]

Is DOF ever an issue with an 800 mm telephoto?

"...others will continue to use EF L series prime glass and an adapter when fast glass is needed."

I imagine Canon wil come out with pro level R lenses in time.  But the 1DX Mk III is still the king and will be for a while a long while. This is just the Rebel and kit lens level stuff.  f11, yeah, right!
