next PZ lens test report: Panasonic Lumix G 14mm f/2.5 ASPH
#1
Tiny and light-weight pancake with decent resolution capabilities...

Thanks so much for testing this lens. I almost bought it today.



You say: "The resolution capabilities are only decent but not stellar for a fixed focal wide angle lens."



SLR Gear says: "The Panasonic 14mm Æ’/2.5G produces very sharp images. ... At Æ’/4 and smaller, the lens is practically tack-sharp across the frame until it starts to hit diffraction limiting at ... The Panasonic 14mm is technically sharper than its 20mm [cousin]"

How can this be? Both sites have a good reputation.

Hi Sebastian,



Thanks for progressing the testing of µFT lenses. It is highly appreciated.



While photozone tests discuss distortion with and without autocorrection, this is not down for CA. As an Olympus user I think the latter is more relevant, since Olympus bodies do not correct CA. Ok, CA correction is part of the raw converter integrated into Olympus viewer, which every Olympus user can download for free, but this takes some time and effort, compared to just sharing out JPEG files. Just a suggestion from my side.



Thanks again for your time on testing the lens.

Hi,



you won't regret buying this lens. As mentioned on the second page the center quality is generally on a very good level and the border and extreme corners show still good results. However, compared to the [url="http://www.opticallimits.com/olympus--four-thirds-lens-tests/464-pana_20_17?start=1"]Panasonic Lumix G 20mm f/1.7 ASPH[/url] the resolution capabilities are only decent. Nevertheless, it's a pretty cool lens and I'm sure you will have very much fun with it.



Bye Sebastian

Hi Joachim,



yes, you are right - there is only a small hint on non auto-corrected CA values.

Your wish is my command - I will provide it in the future.

Cool, thanks, that was quick.



If I can have another proposal, I would put a disclaimer that autocorrection is employed by Panasonic Lumix cameras. (At present your text says cameras).



FYI, I am using ACR via PSE 6.0 and that does not do any CA correction when used with E-P1 files (automatic or manual).



Thanks again for the review. I hope there will be more coming.



Best wishes

Joachim

Slightly disappointing WRT WO sharpness IMHO. I wish it was a bit faster and a bit sharper WO. Possibly both were scarified to create that super tiny design. Maybe the [url="http://www.43rumors.com/ft4-olympus-12mm-f2-0-with-different-design-than-the-mockup/"]rumored 12/2[/url] will be better.

The difference concerning the maximum resolution between the 14 mm (2276) and the 20 mm (2759) lens is truly surprising. A sample issue?
#10
I was also surprised admittedly. But the 14mm showed no centering issues.
