i know this comparison might be done to death, but i cant find good reviews comparing this three lenses head to head, specially considering that at least the Canon 17-40mm is cheaper than the Panasonic 7-14mm.

i want to see how they compare in terms of AF and IQ? Ive personally tried the 17-40 and love it, but would like to have the "same" lens half the size same IQ for my OMD?

I have the Pany 7-14 and the Canon 16-35 ... except for the extra speed of the Canon (2.8 of the Canon is significant but the IBIS of the Oly somewhat compensates), I really find them very similar in IQ. Both are equally a joy to use and both are very sharp.

The 7-14 is probably as good a wide zoom as there is in any system. I sold mine a year ago when I was getting back into full frame, and now that I'm back to m43 I sure wish I had it back. Never used the 9-18 but have heard good things about that as well.

I can vouch for the 7-14's performance... it's probably one of the best M43 UWA.

I've owned both the Canon 17-40 and Oly 9-18 in the past, kinda wish I had the both back. ;-) The 17-40 is a bit slow at f/4 wide open, and can be a bit soft until stopped down, but is an excellent landscape lens @ f/11 for half the price of the 16-35. The Oly 9-18 is very very sharp (and small, and light!) but has significant barrel distortion < 12mm and is a slow lens.

I too would love to see a direct shootout of these three.

wow really?!?!?!. I've used the 16-35 here at work, and i find it the sharpest lens ive ever used yet. So you think the P7-14 is up to the C16-35? thats interesting. but ive heard you cannot attach any filters to it right? no chance of ND filters for Long Exposures? or polarizers?



what do you mean the C17-40mm is a bit slow @ f4? isnt the P7-14 an f4 lens as well? but i think that the OMD and my 5dMKII dont even care shooting at ISO1600 if f4 is the maximum aperture so i dont think its a deal breaker.

and what about the Oly in terms of color rendition?. Im not liking all the CA from panasonic lenses in Olympus bodies.

I have found CA to be a problem when using Panasonic lenses on Olympus bodies, but the lens correction tools in Lightroom 4 deal with this very well. I can't vouch for the 7-14mm, but the 20mm and the 14-140mm (particularly at wide angles) clean up nicely despite each displaying fairly siginificant CA in certain situations.

My copy of the Canon 17-40 was sharp wide open and a nice package. I'd say it was sharper than my 16-35mm f/2.8L but the extra aperture was very nice to have. In the end, I found myself not using either enough and selling them. I've generally gravitated towards prime lenses with the 24 f/1.4L being ideal for me.

To tell you the truth, from what I have seen most would be happy with any of them. I like the 9-18mm because of its size but I agree there's a bit of distortion at the wide end. I may be incorrect but its worse on a Panasonic body because Olympus corrects in software. I should head to my local shop and ask if I can borrow a 7-14mm to compare.

that makes totally sense to me. yet the problem is that here in NZ m43 stuff is limited, and even sectored meaning, if a store carries olympus doesnt sell Pana lenses and vice versa. i havent found a store yet that carries both. but if any of you guys in this forum have some of this lenses to shoot some small comparisons it would be much appreciated!

there are probably more threads comparing the 7-14 vs 9-18 than anything else on this forum.
