Canon EF glass probably isn't done just yet, but...

I personally think super teles version 2 lens are going to maintain value better than ever before

300 F/2.8
500F/4
600 F/4

^^^^ these will maintain value and prices ^^^^^

I think that with RF technology they will resort to DO technology and make the super teles smaller and lighter and more hand holdable and that will be the selling points.....the optics on Version 2 super teles are excellent....not sure how going R mount will make them any better

I am 69, and can probably die with EF lenses!

Dropping $3000-4000 on an equivalent level (to what I have) R series body, and THEN spend thousands more in buying new R mount lenses to replace the full range EF mount lens FL that I have, just to have 'the ultimate' in IQ...I don't need those bragging rights to sustain my self respect as a 'Man'.

Same boat

64 and probably another year or two shooting less weddings. I still love to shoot weddings. Its the last place to really practice true photojournalistic photography

But wildlife is a hobby for me. There no $$$ in it. Its more for bragging rights...sports photography is just about Dead...tough to make $$ to pay for the gear now

Of the lenses I have I'd like to see Canon take another swing at the 24-105 f/4L. The 2nd version just wasn't enough of an improvement.

My 24mm f/1.4L ii, and 100mm f/2.8L macro USM are like 11-12 years old so an updated version should be better but how much better can they become?

There is some evidence that optical quality control is more difficult with DO. Contrast and light-transmission efficiency have also been noted as being behind more conventional refractive optics. The first Canon DO lens was not a market beater in spite of its weight and size compared to same FL range with conventional optics. Folks complained about it being 'soft'. So what has gotten better in 12-13 years with DO designs?

Yeah But

have you tried the 400DO version 2

OMG its as sharp and anything I have ever used

I didnt want to spend 8K to be at 400MM

but it works great with TCs

I want a 500F4--cant afford

Glad to hear you like it. In reading reviews of the 400 DO the most common critique seems to be in contrast, not sharpness per se.

dude you are old! i'll be 65 next month

not the 400 DO II, wilt.

OK, important distinction!

OK, let's assume Canon EF lenses are going the way of the Dodo. What does that mean for my EFs gear? Will that go, too? I've sold off all of my EF gear and moved exclusively to APSc/EFs. One caveat; I still shoot Pentax medium format 645N. If Canon moves on from EF, won't they be deserting a hoard of Rebel using soccer mom's and the like? This is a real pipe dream: efs 15mm & 24mm f/2 & efs 100-400 or so. For the 100-400, I could buy a Sigma, but it is made for full frame, which means heavy and expensive compared to the likes of the 55-250 STM.

I wouldn't hold my breath for exotic ef-s lenses. but i'm not sure about the future of crop and the ef-s lenses. I know once I get a 45mp FF I won't have any need for a crop sensor other than the one in my iPhone 11 pro.

Wilt that would be a version 1

The version 2's are very very nice...I came darn close to getting one

I'm 63 years old and have all the gear I want/need except the Canon 100mm 2.8 IS macro which I will acquire soon. I really don't care what new gadget they come up with, I'm with the "EF till the wheels fall off club".

I'm OK with no special efs glass. I can always pick up a 5D2 or 6D again, if I need to use EF primes. As far as zooms go, crop-sensor stuff works for me. List: Sigma 8-16, Tokina 12-28, 18-135 USM, 55-250 STM. My photographic gear is slowly moving backwards. EF stuff is all gone now, bodies and lenses. That move was predominantly to have smaller, lighter gear. Then I picked up a Pentax 645 on E-bay for next to nothing. That led to a pair of 645N bodies and a collection of FA (autofocus) lenses. No weight savings there! Having 120 film on hand raised the question, "What other cameras use this film." I've since acquired a half-dozen medium format folding cameras, the oldest is from the late '40s. I suppose if I can make good use of 80 year old cameras, I should be able to live out my life being happy and fulfilled with my efs stuff.

The move to RF (?) glass will snowball in the coming years. In a few years, if all goes according to my evil plan, I should be able to get a 5D3 and a few L-primes off of E-bay for what an AE-1P is going for today. Progress, ya know?

that's a good way to look at it. there's plenty of EF glass out there and will be for some time. tho I would look at getting 5d4 or EOS R or even 6d2 rather than 5d3. I owned the 5d3 for almost five years and you can pound nails with it but the DR of the newer cameras is a big deal.
