Hi guys,

I finally got some time to test these 2 lenses. Shot with 5DII, RAW, from tripod with live view focus. Just exported from lightroom, PP whatsoever.

The image:




Crops:

















You can judge it by yourselves, but what I see is that Zuiko hits sweet spot @f4 already and doesnt improve much after that. However It is sharper in center @f4 than 17-40L at any aperture Very Happy. It is very very good wide open, almost excellent. Canon just whiskers it in the corners, mainly in the top right. Top left corner they seem to be equall.

I know its not fair to compare a wide with a zoom, but this thing is so tiny! Its probably 3-4 times smaller and lighter than canon zoom.

I've never owned a zoom in 30 years as a pro but sometimes I do rent the Canon 17-40 L.
Your test illustrates the superiority of prime lenses over zooms.

Time to compare the distortion? for me at least is one of the most important parameters, even if not doing architecture I have found problems with horizons and certain lenses...

The Zuiko 24 + PTLens is a killer combo.

Forgot to mention that, thanks for pointing it out.

Zuiko exibits quite a bit more distortion than canon. It also vignetes more, but not much.


If this Zuiko had autofocus, 17-40L would have been long gone. Since I went full frame I rarely use 17mm setting, its to wide and has a lot of distortion fir things I shoot. Since I shoot weddings AF is a must. I do shoot a lot of stuff 2ith manual lenses at weddings, but only when I can afford to miss some shots Smile.

From my last wedding, Yashica ML 50 1.4. I slightly missed the focus (and as always, on the photo I like the most, the rest from series are spot on but not quite like this one).

I can't see any diff between Canon and Zuiko but you can't zoom with Zuiko Smile

I can see a word PIVO (beer) on the parasol Smile

I would sell Zuiko and keep Canon 17-40 L

However, I am impressed by your pictures taken with Yashica -

I have tried this lens but I don't like it. I think Yahica 50 f1.4 is a strange lens. Nice colours though

The 17-40 has it's flaws but it's still an excellent lens, although it is NEVER sharp in the corners at 17mm, NEVER. It is sharpest at F11, not F8, so in this case it may have been worthwhile comparing them at F11 as well (although it probably still wouldn't be sharper than the Zuiko).

this Canon zoom is a very very nice lens! - because imo the Zuiko MC 24mm is hard to beat Wink

I & my friend compared my Tokina RMC 35-70/4 to canon 17-40L
My Tokina is not lost in term of sharpness. my friend who only play with AF lenses, shocked Very Happy

I lent Tokina AT-X 3.5/17mm to a friend who shoots weddings with Canon gear and uses the 17-40L.

She was upset that the Tokina was quite a lot better than the Canon at 17mm setting.

I don't know exactly how it was better but she kept the Tokina for 3 months before finally buying it from me so she must have rated it highly.

You can zoom with the Zuiko, but it's rather a drawn out affair and sometimes difficult, you walk forwards or backwards until you reach the desired distance Laughing

Love the Golf by the way, always wanted one.

I call this Zuiko poor men's Distagon. It's the only 24mm along 25mm ZF Distagon I decided to keep. Due to it's optical quality and tiny size.

Why oh why did I click on this thread?

I've wanted the 24mm Zuiko for over a year now. It's the only lens I've never come around buying. I was going to buy one but the seller sold it someone else who came by to pick up another lens he was selling. NOOO!

I really want the 24mm Zuiko. I might even dish out the extra cash for the 24mm f/2 version. How do those two compare optically?

This was tested with 17-40 @ 24mm, at 17mm it would have been a no contest really Wink. 17-40 starts to shine @5.6 and @20mm and up. I never liked 17-40 on a crop, on a full frame it almost becomes a different lens. Fantastic IQ for the money considering its a zoom and can go to 17mm...Very fast autofocus as well.

Zuiko just blows me away wide open. It has nice bokeh as well. At f4 and up quality is unbelievable considering the size of this lens, and the fact it cost me $100 together with 55 1.2. However, It looks so funny on 5D Smile

Yashica 50 1.4 ML is fantastic, I love this lens and i shoot it only wide open. Im considering selling all my other fifties because of it. Here is one more...

If C/Y Planar 50 1.4 is noticeably better than this lens, Im would probably trade my Zuiko 55 1.2 for it...Smile
