manmachine242: I've never seen such a bad bokeh quality in the "transition zone". It looks like we were playing with cheap C-mount CCTV lenses and adapters.
Look at the dog's hair and nose, or the lady's hair.
This is simply unacceptable in this price range.

I absolutely agree. Anything above 24mpix is excessive, and examining an image of a higher resolution at 100% magnification often leads to conclusions that have nothing in common with how the image looks in print. The reason is that an optimal angle of view, according to THX at least, is 40 degrees, which makes an optimal distance to enjoy a 55"-diagonal print about 7 feet. From this distance it is impossible to notice a difference between 24 and 47 megapixel file printed at 180ppi.

The dog's nose just shows the photographer's ability to choose the correct DOF, or rather lack of it thereof. Are you expecting to see flawless rendering in front of the focus plane on a lens optimized for the posterior bokeh? If you don't like it, get yourself a $100 enlarger lens and enjoy the beauty of the front OOF areas at the expense of the background.

The hair claim is utterly preposterous. A cheap lens, whether zoom or not, would produce fringing consistent with lateral CA. What I see here is just high local contrast, which is here by design in order to improve the lens' ability to render depth. If you don't like it, there is a Sigma lens galore for you where you are free to enjoy flat rendering and eye-burning edge sharpness.

aris14: 24-70 and 70-200mm are the frequently used zoom lenses, a must exist for any cam manufacturer and this Pana lens seems to be a very good one.
Rather "shallow" gallery though.

@Dave Oddie - 2.8/24-70 is a professional photojournalism standard. It is plenty fast, especially with these new cameras that shoot comfortably at ISO1600-3200 and covers 90% of assignments. I am not sure what kind of appeal you are referring to. That being said, 100% of jobs in 2019 I did with Leica 24-90.

marc petzold: There is some kind of 3D Pop, you can see it, "feel" it into the sample pictures. Panasonic also explains that with their Lumix S Lenses by Design onto their Homepage. Well done. Not like some Leica, Voigtländer & Zeiss Lenses, but still...it's being there, with this Zoom, the way it does render images. Those pictures show depth. ;)

Pana also writes further: "The optical performance of this LUMIX S PRO lens is remarkably high to clear stringent LEICA standards."

A fine Evening, and good Light.

in fact, what I see here is awfully close to the rendering of Leica 24-90

Could you elaborate? Apparently you are seeing something that I am not. What I see is stellar performance against the light, neutral bokeh and very good local contrast.

catlyn: Why bother with it when there is the brand new Sigma DN 24-70 f/2.8 L-mount for $1000 less? :) The Sigma looks solid, and in the last few years it has proven, as a company, that it can make great lenses for good prices (and sometimes -- I mean Art series -- for huge weights and sizes, compared to peers).

And this time -- i.e., for the L-mount -- Sigma is not "3rd party", but "1st party" (or "2nd party"?)

Marc, I have the 24-90 lens. It is in all respects flawless except one: it produces massive glare when there is an open light source just outside of the frame on the left, and nothing of the kind when the light is in any other place. I tested several copies of the lens, and they all have an exactly the same issue.
Obviously, this can be used for artistic purposes, as the effect is very predictable.
Going back to this Panasonic S Pro zoom, from these pictures here I can conclude that there is nothing of the kind happening. The image feels very similar to the Leica zoom: there is the same richness of colors and 3D depth.

I am still patiently waiting for the L-mount option.

D200_4me: Honestly, I like the well controlled flare of my Nikon 24-70 f/4 S lens when shooting into the sun. Seems to be much smoother and better looking overall than the Panasonic examples here.

Indeed, there is always a trade-off between the aperture and image quality, at least in zoom lenses. At f/8 all lenses look stellar :)

Horshack: At $2,200/USD this lens will be a tough sell vs the Sigma 24-70 f/2.8 DN selling for $1,100/USD. That said, samples look nice except for some softness on the right 1/3 of frame at 24mm (#26).

there are a few reasons to choose this lens despite two-fold price difference. It is definitely optically better, I can see this even on this examples. Also, unlike Sigma, it is parfocal, and its focusing system can be linearized for cine work. Not sure if Sigma made any claims on being waterproof, while this lens can be used under the pouring rain.

stop down to f/4 and get the same performance :)

Yes, Sigma looks solid on the outside, and that's basically it :)
Optically this new lens is on par with Leica 24-90, but better at holding flare at bay.

looks like it controls flare much better than Leica 24-90

mailman88: Gift fails....a family member overheard me say, “I need to buy a tripod.” You guessed it, I got a brand new tripod for my birthday.
Without researching my gear or asking questions about tripods...my new tripod couldn’t handle my gear. Had to return and upgrade my tripod, which cost $159.00 more. My family had no idea what a ball head was.

Your family probably had no idea what Gitzo was either :)

Well, actually, a photographic print of the victim's masterpiece inside of a high-end toilet bowl would definitely be remembered for a very long time.

AF tracking is obviously the most valuable feature for landscape photographers, even more so than the burst speed :)))))

In reply to:

Robert Tolputt: Mmm........lets sum this up

.....decreases horizontal resolution by 1.8x
.....introduces nasty flares and CA
.....poor MFD requiring suggested $500 diopter

alternatively you could use any lens of your choice and crop the result, but then Hipsters would not be able to pretend they were a DoP on some 60s Hollywood backlot.

Not quite. 6K anamorphic resolution of GH5 is 4992×3744, and it does not change the horizontal pixel count during transformation. Instead, while transforming into a full-width frame, the software changes pixel shape from rectangular to square.

In reply to:

panther fan: I never understood the hype around anamorphic. There are essentially three things that describe the anamorphic look

1. Wide aspect ratio and the resulting perspective change, because a frame-filling subject has to stand further back
2. Oval shaped bokeh
3. Horizontal flares

Why exactly do we need complex anamorphic lenses for that? For the first effect simply crop your frame (and use a wider lens than normal [with a larger than normal aperture]). For the second two, you can mod a regular lens to do the same. Bokeh shape is related to aperture shape, and vertical "flare" elements inside a lens will result in horizontal flares. So why don't we go with modded regular lenses? Some manufacturers could sell them even prebuild if there is really a market for it.

Essentially, anamorphic lens combines qualities of telephoto and wide lenses, which is not possible otherwise without losing resolution. Simple cropping does achieve the same look, but you will definitely see the difference in sharpness on a big screen.

Anamorphic lenses do not decrease horizontal resolution of the final product. When you shoot in 6K and produce in 4K, you get full res across the frame after desqueezing.
Granted, this lens is not something to write home about with respect to sharpness and aberrations, it gives pretty affordable access to video and indy filmmakers to a powerful imaging tool, which they would not otherwise have.

davev8: i found the lens flare very annoying to watch

anamorphic flare is very interesting to work with in dynamic scenes, but here, I guess, it was just to show that the lens can do it :)

indeed, Pro attached to an iPhone name sounded like a fallacy, and pro air buds sealed the word's fate. Unless of course somebody will be using them to earn his living.
