p.1 #1 · p.1 #1 · Mirrorless - Rediscovering EF Glass


I've been cycling through some EF glass and it's strange but SOME of the lenses feel different somehow - it's probably just imagination coupled with the center of balance further forward with the adaptor.

I have the oddball EF 40mm f2.8 pancake...... I had it just as a really light weight setup for occasional use and I picked it up really cheaply.
- On an older dSLR it was always meh to me, nothing wrong exactly just not fast or responsive and slow-ish to focus and at f2.8 not especially fast (so used the 50f1.4 a lot more).
- On the mirrorless, It's far better than I remember. It can use the faster shutter speed and for some reason it's effortless and snaps to focus. I guess it's the STM motor but I found it interesting.

Some EF lenses work better than others. The older ones have limited FPS in MS mode and of course the incessantly running IS is not ideal. A 45/2.8 seems trivial to AF on most bodies, even an old 1DXII. Which cameras are you using?

The 40mm 2.8 stm is known for being very very good. I’ve used it many times (have three copies) I’ve always got at least one body with the “forty” mounted.
Did you ever update your firmware for it?
I did and it definitely improved the focus…became more fluid.

Old was 5d2/7D and new R6ii... so light years difference.

It has firmware? That would be a no ;-) Defn going to look into that but even as it is, it's become a far more usable lens for me.

I know I have to stop thinking of mirrorless as just another dSLR - but that's what it is in my head somewhere.

I loved the old Canon pancakes on my DSLRs. The EF-S 24 2.8 STM was my fav—beautiful rendering and sharp. AF was extremely reliable and reasonably peppy. Great travel companion on my SL1. I went through two copies of the EF 40 2.8. The first one was horrid—very soft and AF slow and not reliable. The second one, a refurb a few years later, was excellent, albeit AF was still a bit slow and noisy (like a sound effect from "Tron"). I used the EF-S 24 2.8 STM on my R7 for a while with excellent results but the adapter ruins the pancake vibe, ditto for the EF 40 2.8. I bought the RF 28 2.8 STM pancake and, while a decent lens, isn't as good as the two older pancakes—requires lots of correction in corners. The older pancakes were pretty good without a correction profile.

For me it’s been the Sigma Art lenses. Focus was occasionally inconsistent on my DSLRs but they’ve been perfect on my EOS R. In-camera corrections are also supported so it feels just as nice as using first party glass. It continually surprises me how much better these lenses are on mirrorless.

I am buying up most of the Sigma ART primes. All except 20, 24 and 35mm. They are much weaker. Much weaker. I got Tamron 35mm f/1.4 and that's excellent. I don't like native RF glass; 50 and 85mm f/1.2 would be nice to have for optical quality but for the price of one I can now vacuum up most of ART glass with 98% IQ. Focus is great, resolution insane and they work fine in video mode too.
Remember EF mount is still pretty current for cine cameras along with Sony E and I expect it to remain so for a good while. Likewise it adapts to RF, Z, E and even GFX so I'm going to gamble on it.

I sold my EF-S 24 with the gear the R7 replaced. I've been impressed with the way my 10-18, 35, and 60 EF-S lenses handle on my R7. No replacement RF-S lenses for those yet or maybe ever. I repurchased the 24 and it is really nice on the R7 and I'll be carrying the adapter anyway. Thought about the 40 for my R5 but I don't usually carry the adapter with that body. Some options work, some don't.

Love the Zeiss Milvus 35/50/85/135 on my R5. Perfect to slow down a bit but easy to nail manual focus at f/1.4.

Also added the EF 135mm f/2 to my RF kit. Don't see a reason for me to buy/justify the RF version.

Good to hear that I’m not crazy for being disappointed in the sigma 24mm. I do love that Tamron 35 1.4!

I avoided 3rd party lenses back in my 5d days, for focus reasons, but mirrorless really unlocked a lot of 3rd party options for me. I do love a bunch of 1.2 and 1.4 rf lenses though.

I've only got a 16mm 2.8, 24-105L, and 800 f/11 in RF. All my other stuff is my old EF, and they all work great. I just did some photos for a friend's highschooler with the SIgma 50mm ART and 135L canon. They were crystal clear.

Only thing I can say is the RF24-105L is way better than the EF (v1) that i had. And I loved that EF model. But the RF is sharper, faster to focus. So maybe there is something to be had with the RF upgraded models, but it doesn't mean you have to throw away your EF Glass. Plenty of life left in it!!

I agree about the EF glass, but I have to add that the 100-400 f8 is a very handy lens on my R7. It focuses very close, yesterday afternoon at beer time I got some nice shots of a mosquito on a tiny flower and then caught a red tail in flight as it circled around. The tracking worked well on both. A fun combination.

I would in say primes have better potential to stay relevant, particularly anything under 70mm. On R6 you shouldn't notice much difference; on R5 it may be so magnified that you still can't shoot with zooms, period. 24-105 is a superzoom and corners still suffer a great deal even if it is a noticeable improvement over mk1. I'm actually concerned if RF would be enough of an improvement over EF 24-70mm f/2.8 II and it feels like it is a waste of £££ with same smeary corners and massive curvature. You start to want absolutely perfection at these prices and I'm not convinced they are.

Welcome to computational lens designs. "Smeary corners and massive curvature" are features, not defects, and are expressly designed to work with lens profiles for corrections. The "benefit" for us is slightly smaller and lighter lenses and larger zoom ratios. I don't like the idea of replying on correction profiles but then I don't care so long as the end result is good. Oddly, I often toggle the profile off as I like the natural vignette, and the barreling usually doesn't matter for nature subjects. By the time it is cropped and matted, the extreme corners are long gone.

I just played with an uncorrected image from the 24-240, a lens that freaks out people who look at uncorrected images. Even uncorrected, a 16:9 or 4:3 crop nearly misses the black corners. An 8x10 crop misses them completely, but some darkness is still visible in the corner containing the sky. Apply lens corrections, crop slightly, or use a crop body and it's a non-issue. Oh no, the out of focus extreme corners of my uncropped image are slightly dimmer or have less, um, detail. The horror. My image is ruined.

I know guys who enjoy viewing the corners of brick wall and newsprint images at 400% just so they can whine and beat their chests on forums and FB groups.

Yeah, I'm really liking the flexi of the 24-240 lens - glad I didn't go down the default RF24-105 path (I still have the EFv1 copy that I love) and gave this one a try despite what the internet seems to say about it. I've set a default import profile to just do the lens correction and CA without showing me. As I mentioned upstream, it's like a secret that I know in my head but thats a me ting not reflected in the images. I'm really not missing the 24-105L (I know that's unfair because I'm comparing against the v1 copy which is likely the worst of the three)... Now I AM missing the 70-200L... Even stupid me can see that one has a look that is not in this 24-240.

While on the trio of f4 L zoom's.... I'm liking the 17-40 more than I thought. To me it was always.... well not the Cinderella of the three. Balance with the adaptor is really good.

I have an EF 70-200 2.8 IS II. It comes out when I need f/2.8, such as shooting my daughter's flag football game at night, or when I want lots of bokeh, such as holiday photos at the park.

I had an EF 24-105 f/4L back when I owned a 5D. It wasn't terrible, but it definitely benefitted from being stopped down a bit. I have an EF 24-70 2.8 now and probably will for a long time due to RF lens costs. It too comes out when I need f/2.8.

I also owned an EF 17-40. I'd say it was similar to the 24-105. I have the EF 16-35 f/4 now and it's much sharper. I just don't like how big it is once adapted. Somehow I have it in my head that wide angle lenses should be small, but this adapted combo isn't. I've toyed with the idea of replacing it with an RF 15-30 but the pricing doesn't favor that now.

I'm hoping that my 14-35 and 16 f2.8 are actually a bit wider uncorrected on my R7 than advertised so they are closer to 12 and 15. Had my RF kit for over 6 month and haven't actually tested this.

Isn't the 14mm measured near the center of the lens? Is Canon up to some shenanigans?
