Showcase Panasonic 42.5 f/1.7

Anyone have some test photo's from the Panasonic 42.5 f/1.7? Is it just a clone of the Olympus?

Panasonic & Olympus do not clone, copy, or share lens designs.

(the mount design and most electronic standards are shared by m43 partners)

Someone posted some results from a Swedish site that did a comparison between the Oly 45 and both the Panasonic 42.5s. Seems the order was 42.5/1.2, 42.5/1.7, 45. The new 1.7 was notably better in the corners than the Oly.

It's here, the Swedish review:

hi admin, maybe this thread should be merged with these threads?

Hi, thanks for the response guys. Maybe my intention was not quite clear. I was looking for user shots from people who own the lens. Just like the other threads in this forum.

The lens hasn't been released yet....

Bunch of shots from yesterday and today taken with GM5. It is a long post, but hopefully it shows the lens character like the bokeh and the mfd... Exif's are in the photos...

Hmm, the bokeh seems very busy...

Serhan · May 3, 2015

Because they were shot against busy backgrounds

It's f/1.7 lens, so I don't expect miracles. I like it a lot so far. The advantage is the 1:2 macro mfd. There are not many lenses that can do that esp with its size and its aperture is faster then regular macro lenses. It is perfect for gm5.

You're right, these last ones have much nicer OOF backgrounds. Did you ever own an Olympus 45mm? If so how do you find it in comparison?

Serhan · May 16, 2015

I have Oly 45mm also, but I have not compared them. I use gm5 most of the time and that is one of the reasons I got the lens plus the mfd... I wanted a black 45mm anyway

I think cameralabs did a good comparison of these 42.5 and 45mm lenses:

It looks like he compared 42.5mm to the new 30mm macro also in his 30mm review:

Thanks for posting those reviews. The comparison with the Oly 45 was interesting with the 45 delivering some pretty poor corner sharpness. I've never noticed anything that bad with my copy - I think I'll do my own test and see if Gordon Laing's result is an outlier or not.

I would keep in mind some of Gordon's words from the review:

"Indeed the Olympus looks quite poor in this comparison, but this performance is not uncommon for most lenses, which are generally softer in the extreme corners at their wider apertures. It's the Lumix here that's performing above average."

tkbslc · May 16, 2015

It is 1:5, which is about twice as close as the Olympus at 1:9.

Serhan · May 16, 2015

I was comparing to FF mfd's, but I was wrong due to sensor size. 42.5mm mfd is roughly twice of PL 45mm mfd so 1:5 sounds right... Zeiss 100 Makro mfd is 1.44x of Canon 100mm mfd which converts to 1/2 magnification...Cameralabs review has that wrong also:

their closest focusing distances are 31cm on the Lumix versus 50cm on the Olympus, delivering 35mm equivalent reproduction of 0.4x versus 0.22x.

fredlong said:
On the four-thirds.org site the close focusing is listed as .2x which is 1:5. Is it actually closer?

Fred

tkbslc · May 16, 2015

It would be equivalent to 1:2.5 on FF so not too far off.
