    Mamiya 28mm testing

    I know this stuff is boring to some but i do like to share testing results sometimes that I think are relevant to folks that want to buy a certain product. I know there is a lot of interest in this lens and i have been skeptical of the soft lower corners I seen elsewhere and noticed before when i tried it but this looks a lot better . i just did some quick shots to see about distortion and stuff before i get real serious with real work. The 28mm looks to be holding very well on distortion and my corners look really good. Now i shot this at F12 which for me would be normal with doing interiors. Nothing fancy here with lighting just popped off the ranger at full blast.

    Re: Mamiya 28mm testing

    This one I did not show the corners because i focused in the middle and the corners are very close so there out of focus . So really makes no sense showing them but did add the center crop and the detail is really good. F12 again. I think if you can't stop down more in a shot like this than maybe the focusing software helicon maybe a good choice. Normally without the windows you could stop down more and just add more pops to the flash for that extra DOF needed

    Re: Mamiya 28mm testing

    It is hard with a 3d subject, where the corners are so much closer than the middle, to really see if the corners are holding up. Hard to tell dof vs field curvature, vs corner aberrations.
    A good subject would be the side of an old barn.

    Re: Mamiya 28mm testing

    Don't forget that Capture One 4.5 Pro will offer
    - vignette correction/control (the 28mm has SLIGHT fall-out)
    - sharpness falloff correction
    - barrel distortion correction / pin-cushion correction

    All of these will be automatically applied in Capture One 4.5 Pro (with the option to turn them off) which will help these shots look even better.

    We'll have a seminar in South Beach the evening of October 14th (the day before the public release) to show off the features/functionality/workflow/tips/tricks of C1 4.5 Pro. Beer will be plentiful.

    I am looking forward to 4.5 Doug . I bought this lens knowing that improvements can be made in the pro version. I actually planned ahead. Scary thought

    My guess is a masked sharpening with smoothly progressive radius. In other words, sharpen for the known radius of real detail for each section of the print so that while micro-detail falls off (unavoidable) the appearance of "unsharpness" is removed while not affecting the part of the image which is optically perfect.

    Guess we'll see in a few weeks.

    Re: Mamiya 28mm testing

    Thanks Don you realize looking at some of the captures you done with it put me over the edge. So far i really like it and it should do exactly what i need. I'm trying to get Jack to pull the trigger on one.

    I am a really bad influence to hang out with.

    I am a really bad influence to hang out with.
    I知 off to the North Rim in a week where among other things I値l be testing a Cambo WDS P45 with about 3 lenses to boot (thanks Chris & Dave). This will give me a chance to shoot side by side with the P30+ and P45 (not sure if it値l be a plus back yet) and compare among other things how well the Mamiya 28mm holds up with the P45.

    I致e never shot a TC before and this will also allow me the chance to see if this is where I want to take my landscape work to. Trying not to have any preconceived notions but unless I really can稚 grasp the new shooting style (set f/stop, shutter speed, set shutter, etc) I think it値l be a winner. I値l have the kit for a week and should have a good enough grasp of what it値l take to get a good image by the time I have to give it back and place my order. Never thought I壇 consider trading my P30+ but will have to if I decide to get the Cambo; good thing is that the trade up to P45+ seems doable.

    I plan to share comparisons when I return.

    Guy so it looks like you値l be set for the house shoot coming up. Looks like I値l have a quasi-similar gig here in Tucson shooting pre-construction shots for a upcoming second phase (I got to do phase one last year).


    don


    Just have Jack touch the lens a good friend of mine, Ken Doo & I have a system that if we touch it we have to buy one (gotta learn to keep my hands in my pocket when I visit him)

    That's a pretty nice looking lens you got there, Guy. Thanks for the test shots, I was wondering how the lens resolved with a MFDB. It's very impressive to say the least!

    Check this out , just really cool how C1 can correct your images and the 28mm CA and or purple fringing that it can have. Normal shot than the crop

    Jack is thinking that is trouble. LOL

    Seriously though that image is really pushing the limits of a lens with that exposure outside. That is a huge blow out, on purpose of course.

    I would love to be there myself. I have to say working with Doug on the workshop and him being my digital tech. guy, i was really impressed by his knowledge. I don't say stuff like that lightly either. Anyone in Florida get's a chance to see that demo should run and not walk there.

    Doug is a rising star for PhaseOne and Capture Integration!

    For wide angle I opted for the new Nikkor PC 24 full medium format image on my Sinar 54H in 16 shots mode.

    Hey Guy, any ideas or opinions on why the 28mm is a lot more expensive than the rest of the Mamiya AFD line?
