Simon, none of the images you've posted look properly focussed. I don't think you have a corner sharpness issue - I think there's something wrong with the focussing of your AFD II or the lens.

Ignoring the corners for now, you should be getting detail in the center than jumps off the page. I routinely get much sharper shots, even with my 55-110, which is notoriously soft.

Can any one who also owns a Mamiya AF 28mm f4.5D lens please have a look at these test shots and can tell me if there lens has the softness in the bottom corners.

So when I go back to Mamiya Japan I have some backup from other photographers who have this lens

 look forward to your thoughts

Regards

Here is shot I took last August when I was testing my 28 mm. 1/180 sec @ f11, iso 50. I was focussed at infinity and was most interested in DOF - hence the subject.

The "0" quality jpg is awful but serves to show pretty good sharpness except at the very edges - tho' in a 20 by 24 print the whole thing is crisp and sharp. Don't look at the leaves - it was very windy!

Hi Bill,

Thanks for putting up your image very nice.

Had a look at your image in Photoshop and there is some softness in the bottom left by the right side is perfect.

So I am coming to the conclusion that my lens is a dud.

I will be making a call to Mamiya Japan on Thursday so If you and any other photographers can prove my case this would be great.

Cheers

Hi Bill. I assume all of the color artefacts are because of the low quality JPEG?

I have to say that if this is representative of the 28, then I'm disappointed. I get sharper images with my 35/3.5. You mentioned it was windy, so maybe there was some tripod shake. In particular, I was looking at the small huts further out in the scene, since you mentioned you were focussed at infinity.

The jpg sucks! The only way I could get the file small enough to post was at a quality of "0". Even then it was 1.8 megs. There are artifacts everywhere. Keep in mind too that there was virtually no sharpening applied, which is hardly real world!

Next week, hopefully, my website will be up and running and I'll post a real file. Meantime, take it from me that the 28 mm is much crisper than the 35 mm - or at least, MY 35 mm! (Which is a pretty good lens imho despite comments I see about softness.)

Anyway, the pictures I'm getting are really nice and sharp and you'll have to pry the 28 mm from my cold dead hands!

Hi Bill,

Had a chance to do a couple really quick shots around the house this morning.  None of these images will win any awards - their are here as examples of the lens quality only.  I do have a few quality landscape images using this lens which by the way I just absolutely LOVE!

Three test images:  Image 1 shot at f/8.0  image 2 shot at f/32 and image 3 was shot at f/4.5

Hope these help.  Go to my website and South Rim Grand Canyon to see landscape images with the 28 or to Limited Editions.  

BTW - sorry no pool shots as we don't have one!

I thought that there were some better samples posted somewhere on this board a few months ago.

Looking at these, I'm amazed at how much better my schneider digitar 24 is... I know rainer will say how much better the 28HR is (needs to be at that price).

As the mamiya is a similar cost to my 24 digitar, I'd hope it could match the quality. This looks rather disappointing

Happy New Year Don,

Just had a look at your images thru hazy eyes this New Year morning.

I can definitely see that your 28mm is sharper which will make my case better when I contact Mamiya Japan.

Would it be OK if I can use these images to show them the difference to mine.

Regards

Simon

Hello,

Well this morning I spoke to my contact at Mamiya Japan.

As it was her first day back from holidays she said she need about a hour to read all my twelve emails.

An hour latter she emailed me to tell me to post my Mamiya 28mm lens back to her for a replacement.

I am very pleased with the fast responds I got from Mamiya Japan and hopefully the replacement will do the trick.

Just like to thank the photographers who sent sample images taken with there Mamiya 28mm lens

I think that this is a bit of an unrealistic expectation as the digitar lens does not have to deal with the back focus issues of the SLR mounted lens, thats probably where the money went.

Hi David,

I agree with your comment about the digitar lenses.

But when you compare my test images to the one's supplied by other photographers Mamiya 28mm lenses it is clear that there images are sharper than the one I have.

And so has Mamiya Japan that's why they have asked me to return it for replacement.

I don't expect it to compare to a digitar

The days of me humping a Sinar P2 around New Zealand are long gone for me.

Hi Simon,
I think you shouldn't be spending that sort of money on a lens and get a dud. Its good you've pursued it. If they aren't adequately testing these lenses, a few getting returned would hopefully get them to tighten their QC.

BTW, You don't need to hump a P2, I just got one of the Cambo WDS with a 24mm apo digitar from Chris at Capture Integration on a very good special last month (advertised in the LL FS forum).  I have squeezed it into a Pelican 1400 case I used to keep my filters in for now. Its nothing compared to the 1600 case I keep the H1 gear in.
cheers

Giddy David,

I purchased the Mamiya 28mm to complement the rest of my Mamiya 645AFDII kit.

Yes in a perfect world, if my lens hadn't been faulty I wouldn't had to put up this forum to get advise.

Manufactures are not always perfect.

A good example is the recall of 86 thousand Holden cars in Australia and New Zealand ( Chevy's for non Anzac's) just this week.

Regards

Simon

Simon - Glad to hear the good news though sorry you had to go thru it.  Hope the next lens will be a keeper.  Out of all the lens in my kit I think my 28 is the best ...

Hi Don,

I hope so too.

I did ask them that before they send the new 28mm could one of there lens technicians give it a good going over  to make sure its sharp in the corners.

The more I looked at the images you took with your 28mm lens its proof to me how good this lens can be.

Even the image in your living room at f4.5 is superb.

I will keep you posted.

Regards

Simon

Hello,

My new replacement Mamiya 28mm lens arrived at Mamiya New Zealand's distributor Panavision yesterday.

Thanks to Tim Timlin I was aloud to use there Motion picture camera facilities to test the new lens.

My first reaction was my Mamiya 35mm lens which I used as a comparison was very good.

The new Mamiya 28mm lens is a vast improvement on the lens I returned to Mamiya Japan but the top left corner is a bit soft but acceptable and therefore I am happy with this lens.

Personally a lens that cost $6,500.00 NZ dollars should be perfect and Mamiya need to improve the resolution in the corners.

All the test images were take with Leaf Aptus 75 on a tripod with electronic cable mirror up.

Images processed in Adobe bridge CS3 with No Sharpening

I've also sent this link to Mamiya Japan.

Look forward to your opinions

I would like to thank Mamiya Japan for replacing my faulty 28mm lens so quickly

Cheers

Simon

Congrat’s on finally getting a good 28!  Too bad you had to wait so long to get one.

We’re sitting in Carmel CA after a 2 day drive from Tucson, going to meet with good friend and fellow LL member Ken Doo to shot the local landscape of Big Sur and surrounding areas – huge difference from the desert areas that we normally hang out at!  First thing I noticed is there’s a lot more people here.

Anyway please show us some of that beautiful countryside of NZ haven’t been there in close to 20 years.

Hi Don,

Great to hear from you. I have never been to the USA but it is a dream of mine to drive from LA up the east coast to Seattle in a convertible Ford Mustang.
Actually I haven't been past the Equator.

The replacement  Mamiya 28mm lens is great but one thing I've noticed is the focusing seems to be very critical and I get a sharper image when I manually focus.
I am hoping the new Mamiya/Phase camera body will have a improved auto focusing system.

I have a car shot for Lexus this week to do on location around Auckland and in the central North Island and then back to my car studio to do the interiors so the new 28mm is going to get a good workout.

Well Don as it have been 20 years since you were down under in New Zealand, if you decide to come down please feel free to contact me if you are in Auckland as it would be great to meet.

Cheers

Simon
