When the 28P was released I immediately purchased.  I already owned the 30 and it is a superb lens.  I spent the next 2 weeks shooting both lenses on a tripod at each aperture for as detailed comparison as possible at higher magnification to see the differences.  My conclusion that there were as close as any lenses I'd ever compared.  In about 70% of cases despite being very small the 28P have a very slight edge in performance.  I sold the 30 mostly for the reasons of size and weight with the 28P being so much smaller and lighter.  Both superb lenses.  All files processed using Phocus.

Could you please share some of these shots taken with the 28 and the 30 please?

I am very tempted by the 28P, someday, and if you say it beats the 30, that's something I'd like to see...

Unfortunately this site is very difficult to upload an image.  I'm still trying to figure it out.  The difference is only visible at 100% or higher.  The are very close in performance but I made my choice because the 28P is much smaller and lighter, near silent shutter and much lower cost.  If I can figure out to upload images on this site I will.

That's precisely why I'm considering the 28P. I need a wide angle lens and if the quality of the 28P is good enough, even compared to the 30, clearly the size of the lens will make me pick it over the other. I'd like to see if the corners at F8 are close to the 30.

Thanks for the guidance to upload pics.  Overall shot is with 28P f8.  As can be seen using Phocus 2 for RAW conversion the corners of the 28P appear fine.  The details are from this image comparing both lenses at f8.  Like I had mentioned before the IQ of both lenses is outstanding.  The advantage the 28P provides is size, weight, cost and near silent shutter compared to the 30.

Here the overall shots with the 30 and 28P f8.

Thank you for sharing your comparison!

I've superimposed the 100% crops in Photoshop and details are slightly crispier on the 30: overall contrast and microcontrast are higher on the 30. It's also obvious to my eyes in the lightbulbs. Still, the 28 seems impressive and might be good enough...

On the overall images, corners appear a bit more detailed on the 28... That could be tied to contrast in the shadows, I don't know. It seems strange to me.

Are there other owners of the 28 and the 30 who could give their opinion please?

The 28P is lighter, focuses better, is not as loud when the shutter is released and has an attractive price.

However, optically it cannot keep up with the 30mm XCD lens.

Hasselblad defines the 28P for street photography. It is good for that.

For landscape photography, however, the 30mm is better.

I learned something new! Thank you

Ofcourse keep in mind I made the highlight and shadow adjustments in Phocus so there may be some small contrast differences that are user controlled...  Also consider the files I sent would be like looking at a 40x50 inch print.  IQ differences just are not big enough.

In my situation the largest print I ever make is 30x40 inches.  If I can't see the difference in a print that large it doesn't really matter.  I made 30x40 inch prints from 4x5 inch film for many years and my Hasselblad X1Dii IQ is superior to drum scanning 4x5 film.  All I need.  And the size and weight difference has made a joy to shoot the 28P.  Not to mention saving quite a bit of money.  Both fine lenses.

Be sure I always compare MTF charts between close lenses!

That's precisely why I was surprised some would find the 28P better than the 30.

But as I read landscape photographers also used it for that, I wonder if they find the limitations significant or not.

I think the 28P is perfectly fine for landscape photography but you need to be careful with the depth of field placement. In my experience, the 28P (at least my particular lens) has quite noticeable focus shift when you stop down to F8 or beyond (the point of focus shifts backwards when the lens aperture is closed down for the purposes of taking the photo). I have got into the habit of ensuring that the point I focus on is closer to me than where I want it to appear in the actual photograph. I imagine most users wouldn't notice but I'm quite fussy about things like this.

Anyway, the 28P works well for a reasonable (in Hasselblad terms) price. I briefly owned the 30 f/3.2 and I suspect it has the edge over the 28P but it is significantly bulkier and heavier.
