And here are some macros. As already mentioned, I consider this lens not as a typical macro lens, because the focal length is a bit short and the reproduction scale is only 2:1. It makes excellent macro shots for sure, but for me it is a real all-round-lens with a special designation for portraiture.

thank you

Ristretto,
Thank you for the postings. Just what is needed for those who are considering this lens. What a blessing to not have to guess on a 5K purchase. If you have a chance to link to a dng file I would love to see that flying bird shot , or even a full sized jpg, if you have time.

Thanks again !

Lovely representitive images from this lens...thank you! I believe it's probably designed more for portrait and general use than for macro. I say this due to a number of factors....the reproduction ration is 1:2 (not 1:1) and that shake reduction thats now often found in macro 35mm lenses, plays a relatively small role in terms of effectiveness at typical macro ranges. Unfortunately the 90mm effective focal length in 35mm terms on the 645D is only 72mm...a focal length thats on the short side for portraits.

In comparison the 150mm f2.8 who's rendition seems to be designed for wider aperture portraits, has a effective focal length thats more idea (on the 645D...namely 120mm!). It's bokeh for portraits and gentle landscapes is very good.

Lastly the Penatx 120 f4 645 macro is an absolutely superb sharp lens and one of the best performing Penatx 645 lenses. At macro distances it's bokeh is not the smoothest but not unattractive either for most subjects.....it's at normal and longer subject distances that it's OOF areas in terms attractiveness is reduced and sometimes simply fairly unattractive. Still all in all, each of these lenses has a lot to offer, with the 150mm f2.8 and 120 f4 lenses being exceptional buys.

I have a FA 2.8/150mm lens which is undoubtly a good lens. But in direct comparison the new 90mm lens is far ahead in IQ. The compressed jpeg here in the forum canít show the difference, but if you compare the RAW-Files itís obvious.

Perhaps my 150mm-lens is not the best out there? I donít knowÖ

Do you mean sharpness or rendering? Or both and more?
The 150mm is (was) above all a portrait lens, not as clinically sharp as the 120mm. Although people have referred to sample variation in the past for this lens. I'm quite satisfied with mine, but cannot compare it to the 90mm, and your pictures do have a nice rendering I must say.

All in all, I would hope that Pentax upped their game with the new lenses.

Moreover, their used selling price under 1,000 USD make them good bargains too.

@ Ristretto, i have a problem with your last rose picture : it seems to have quite heavy and unlovely pixel artefacts in the upper bokeh.

I just tried my new 6x7 90mm LS on the 645D.
When reading this review, I get the impression the major improvement (beside being a marco lens) is the quality if the leans is not used stopped down heavily.
I can get great quality by using the 90mm LS, too, but I have to stop down to f/11 to get it.
It is really amazing how well Pentax did with improving things here, although it costs quite a lot of money. But if tending to use the lens at f/2.8 or f/4, I think the money has to be spent, my 90mm LS is really soft outside of the center of the picture at these settings.

Yes, you are right . I checked the original RAW file, which don't show these artefacts. So I think there was some problem saving on jpeg, I don't really know...

Both in sharpness and rendering. As I already wrote, the FA 2.8/150mm is not a bad lens (in fact itís a good lens), but in direct comparison the new 90mm has this extra bit of sharpness and clarity, itís more ďcrispyĒ whereas the images from the 150mm seems to have a (very) little haze. Wide open at 2.8 itís more obvious than stopped down.

...and beside having image stabilization, accurate AF, great rendering, soft bokeh and sharpness till the corners...

Seriously, I think you do not justice to this lens if you define the improvements just with "better quality if not stopped down". But all these features come at a price, with this I fully agree to you.

If you really want to extract the benefit of this lens to one point I would say, it is the lack of weakness (besides price and weight...).. I am sure there are lenses out there that are better macros or have a creamier bokeh or are even sharper on the edges etc etc. But there were few which highscores in all disciplines like the 90mm does.

You are right, off course there are more differences. I was just writing from my point of view, for example AF is not important for me, nor os the bokeh if I use the lens stopped down to f/11 or similar only. The old 6x7 90mm LS is sharp to the corners, too, but it needs about f/11 to achieve this.
