Hasselblad XCD 28P

I did one when I first got the 28P, it was against my friend's 30mm. What we both gleaned from that was that my friend's 30 is completely out of spec, the 28 made a mockery of it. As far as I know, he sent the lens in to Hasselblad.
I no longer have the lens, my XCD 30 images are from Banff, and it's a long drive to do the comparisons. ☹ They are exceedingly sharp, but then so are the 21, 45, and 90 images.
Well, the question still stands. According to Hasselblad official datasheetes, a proper 30mm should crush, optically, a 28mm. On a 100MP properly executed shot. I would really love to se a serious side by side with that.

I shot unscientific images in my garden and my 30 does not crush my 28 from first impression. The comparison was not scientific enough to post it here (handheld, af etc.), my feeling is even the newer lenses have maybe slight disadvantages in corners overall they are much better than some make it sound here and in the Hassy forum.
For those who want perfect IQ I guess Rodenstock lenses on a view camera would be the best choice.

For me it is hard not to want it at 100MP and above. Understanding the price point and design of the 28P, I give it a bit of a pass because I rarely need that wide and it takes up little room and weight in the bag.

... you don't have to be sorry with your expensive 28er -
leica sometimes takes very bad old lens designs and sells them as soulful lenses.
probably the 28 will be the most sought after hasselblad lens in the future because it is so bad.

but until then, let's mock it a bit!!!

We're (very) regretfully selling-out of our X system as our needs have shifted, but looks like Hassy fell short of the performance standards it had set w/ prior XCD glass and released a lens with performance very similar to, if not modestly worse than, the older but very nice US$800 (used) HCD 28mm.

I remember looking at the XCD 28V's MTF sheet on it's release thinking "Man, that looks familiar".

Our (now gone) HCD 28/4 was big on the X with it's 95mm filter and the XH or 0.8XH (becoming a 19mm/3.1), but man was it sharp in centre WO and the close-focus was fantastic.

Always happy to see Soup here. And ironically, the sharpest part of this image (perhaps the only part of the image that's close to being sharp) is in the corner. :ROFLMAO:

My workflow with close-up images with the 28P is 1) manually set focus 2) move the camera, watching the focus peaking lights 3) shoot when the in-focus band looks correct. It's focusing with the feet.

Well, Soup decided to move. Bastard. :p

If Leica is selling "very bad old lens designs...as soulful lenses", I assume those buying them find them very good lenses for creating their own soulful images.

The XCD 28P is not a bad lens. Of course, it's always possible to get a bad copy of a lens. For instance, if a retainer for a lens element becomes loose after it's passed inspection and been shipped; you could find an element is out of alignment when you start using it. If new, it could be exchanged or sent it in for a warranty adjustment to bring it back into spec.

From the images I've seen and the comparable MTF charts, the XCD 28P compares favorably to the HCD 28 mm f/4, Rodenstock HR Digaron-S 28 mm f/4.5, and Leica Elmarit-S 30 mm f/2.8 ASPH — all of which are larger, heavier, and more expensive. The XCD 30 mm is a better performer, it's exceptional; but it's also larger, heavier, and more expensive which are its trade-offs.

The 28P appears to me to be an excellent choice for its overall combination of size, weight, cost, and performance.

but until then, let's mock it a bit!!!

Not me... I've never had any lens insult or mock me and I try to return that thoughtfulness in kind. If mocking were to occur, I would prefer the mockers to be mocked. It's better to have balanced mockery, if you have to have any at all.

... this is a mystifying advertisement - fact is, they are poorly constructed lenses, which were sold badly and are therefore rare!

... you are right - it is really cheap.
and if they want to become like leica, they have to become more expensive even with the cheap lenses!!!

... I think this lens is more sad than considerate after all - it would rather be much better than it became!!!

I have no idea what any of that means or what it's based on, but I wish you all the best.

I wish I could see a 28 vs 30 f8 sharpness test on an x2d . Hasselblad’s own MTF data doesn’t look too encouraging ….
I don't have images for you, but since you mentioned the lens data sheets and an "f8 sharpness test"; here are the MTF charts at f/8 from lenses with which many here are already familiar. It's helpful that at least Hasselblad, Leica, Rodenstock, and Zeiss produce useful lens data sheets and make them publicly available. Here are the data sheets (or pages with links to them) for the XCD 28P, XCD 30, HCD 28, Elmarit-S 30, and HR Digaron-S 28.

Clearly, the XCD 30 mm is an exceptionally fine lens. It's notable for its low astigmatism and center to corner consistency in addition to the excellent resolution and contrast throughout its focusing range whether at full aperture or stopped down. I don't see a "crush" of one lens by another, but that's not how I think of different lenses or a word I would use to describe differences between lenses.

If anyone reading this should need assistance with understanding what information MTF charts can provide, this Hasselblad Lens Booklet offers a good basic guide or for more depth Zeiss Technical Articles are always well worth reading.

Good job putting side by side those MTF charts. Seeing the Leica S lens as well as the Rodenstock lens next to the ones under scrutiny is definitely helpful in creating perspective. And yes, the 30 XCD does look like an outlier. I would still like to see some side by side test, if anyone would care enough to make them, precisely in order to see the reality beyond the MTF data.

I'm sorry that I don't have the XCD 30 anymore, so this is with an X1D (only 50MP, but I think you'll get the idea). It is a superb lens. Here is an image I took with it - I uncropped it, so the periphery editing looks weird, but I figured you'd want to see the corners. Shot at f/8. 1/100 sec, ISO 100. Have it printed 30"x40". Totally crisp.

Island near Banff.

PS. If it's so good, why didn't I get a copy when I got back into the X system? It's my least used focal length. I have every Leica S lens except the 30mm. The XCD 28P is so easy to carry that I'll see if it lives on the X2D or whether I go back to the XCD 21. I often say that I really want an XCD 24mm, but cropping the 21mm yields a 64MP image, and I can live with that ;)

One of the few YouTube photography channels I find useful enough to check occasionally for new content is mathphotographer. His most recent video features images captured with the XCD 28P in New York City. I hope you enjoy it.

I am glad my eyes are not as good. So I enjoy shooting the 28 a lot, and my 30 collects dust. Much enjoy the focal lenghts and size. Brought it on a hike yesterday , had fun, and didnt see any problems in the images. i admit to look more at the images than on mtf. I shot images at .4 seconds which were sharp handheld. love the ibis. I dont say the lenses are perfect, but I love it as a compact high quality system.
