m4/3rds vs 4/3rds 7-14mm zooms.
 
I already have the 4/3rds version of this wonderful lens, but it's bulk in comparison to the m4/3rds version when used on the OM-D, is a bit OTT. Has anyone seen a review comparing the image quality of these two? I know the 4/3rds version is built a lot better, but the other, is dramatically smaller and lighter. However, because the difference in rear element to sensor distance is likely to have a negative impact on one of these, I'm left wondering which of these, has been 'compromised'? I wouldn't mind meeting up with someone with the m4/3rds version, but seriously doubt because I've never seen a 7-14mm being used by anyone else, if someone lives a reasonable distance from Reading, in the Uk.

I concur with Andy Westlake's review on dpreview - yes, I'm linking you to dpreview!:

The Panasonic 7-14 is excellent in most respects but do expect to have to correct CA. Maybe a good alternative is the Olympus m.Zuiko 9-18, which is also a lot smaller and lighter, plus cheaper.

There is no M.Zuiko 7-14mm? Did you mean the 9-18mm? The CA from the 7-14mm on an Olympus body is very easily corrected in Lightroom.....

If you call Edinburgh a reasonable distance, you can come up here to check my Panny 7-14 ....

Careful. Don't get lost in those long dark corridors. They're full of Trolls....

If you read their review of the m9-18 it gets a very good one too and I concur with that although can't say the CA's have ever been bad.

I know Andy Westlake quite well and we end up talking for what seem like hours when we meet up - I certainly trust his work. Thankfully it's separate from troll city! :D

Ooops - thanks for spotting that, have corrected it in my post!

Yes, Lightroom 4 CA correction works amazingly well with just one click.

FWIW, this was taken using the Panny 7-14mm at 7mm.

Woo! What a monster. I bet you get no aggro at all with a dog that size. Awesome :)

For some comparison, here are a few dogs photographed from above with the Oly Four thirds 7-14 mm. At 7 mm. I have a thing about dogs noses :D

All taken against a white background.

Sorry DekHog, should have spotted that one, I have, and am referring to the 4/3rds 7-14mm Zukio zoom; I bought this in 2006 pretty soon after the E1 body, also have an E3 and now, OM-D. Have just read the DPReview's Panny 7-14mm review, it's sadly not much good as I'm looking for a Panny (Lumix) Vs Zukio 7-14mm comparative review. Strangely, when summing up this lens, they refer to it being cheaper than the 9-18mm, but make no mention that it's cheaper than the Zukio 7-14mm, which should be the lens they match it up against, rather than the 9-18mm ... As usual, the Zukio, is ignored, as it is invariably the case when magazines do any ultra/super-wide group tests.

Maybe this is because (tongue-in-cheek, whilst holding a big spoon!) the reviewers are mainly Nikon/Canon fanboys and hate being reminded that these two manufacturers still have yet to produce an APS-C zoom which comes near it, even though since 2010, (to rub even more salt in this wound) Sigma began producing in 2010 a 8-16mm zoom (for APS-C users) which is 0.5 degrees wider than Zukio and Panny's 7-14mm zoom ... Come to think of it, THAT lens also doesn't appear in ultra/superwide zoom group tests either .... !!

Cathrine, that last photo makes Emil look like he has some Moomintroll in him :)

Catherine, those are some superb images! I'm guessing that getting them to pose as you wanted, was a bit of a challenge! ... Maybe you used wine-gums?

Hmmm. You're right! I'll have to ask his breeder :D
