    how is the mamiya 645 110mm manual focus lens?

    how does this lens perform?
    Seems very cheap and I like the 110mm view for MF portraits.

    Re: how is the mamiya 645 110mm manual focus lens?

    and then a super naive followup question..
    I see 645M 110mm "C" and "N" versions out there. what is the difference?

    thanks,
    cheers,
    Eric

    Never used either personally Eric, sorry. I can say that generally speaking for Mamiya manual lenses, the N versions are going to be better being the newer designs...

    Re: how is the mamiya 645 110mm manual focus lens?

    Mamiya M645 C lenses are an older, all metal body design. More modern N lenses (again M645) make heavier use of plastics, are obviously lighter and have different coatings giving them a tad more contrast vs C versions. Some think they MAY be a bit more flare resistant, but I've not seen that (at least yet).

    For some M645 lenses, there are also 'interim' S variants - C body style + N coatings. Some of the more modern M645 lenses were only released in N versions.

    The same M645 lens be it a C or N (or S) variant are all unchanged (IIRC) formula-wise. Some new auto-focus/electronic aperture D versions of lenses (which are all N obviously) are another matter (e.g. the 150/2.8A D vs the discontinued manual focus M645 version). One exception to this rule is (IIRC) the 120/4 A macro D (electronic aperture but still manual focus) which is optically identical to the M645 version.

    All else being equal, I tend to prefer the handling and lower contrast of the C variants, but that's just me.

    I'd also love to hear some thoughts on the 110/2.8 if anyone is within earshot.

    Re: how is the mamiya 645 110mm manual focus lens?

    I have one and haven't used it for much more than comparison against an RZ67 110mm f/2.8 with a digital back.

    I didn't see much difference in sharpness, but I did see a noticeable difference in distortion. Not sure what to attribute this to...I tried to frame the shots identically, yet they still looked different.

    It looks a lot like the 80mm f/1.9, trading obviously aperture for length.

    Maybe I'll try it out again this weekend.

    Re: how is the mamiya 645 110mm manual focus lens?

    I ask because (horrors!) I didn't like the version of a Hassy 110mm F lens I had.
    Wide-open, the point of the lens of course, the bokeh was weird bordering on disturbing. Not sure what 'version' it was. PS, I sold it.

    But I still like the 110 framing on the 645 and would like to try a different lens.
    Hadn't thought of using a RZ lens -- I assume you need an adapter to get it on a 645 body?

    What other 110'ish does this crowd like?

    thanks
    Eric

    Eric,

    I used them on their respective cameras...I moved the digital back between the two. I was trying to convince myself that the IQ of the RZ would be noticeably better due to the fixed element lens.

    The crop factor was 1.5x on the 645 and 2.0x on the RZ, so neither used the edges of the lens. Perhaps more visible difference would exist there.

    waiting for the 110mm C lens to arrive...But I'll tell you, my 50mm shift lens arrived last week (for an upcoming architectural shoot) and it is stunningly sharp.
    I think I just replaced my 45mm AF lens!

    quick afternoon test with MANUAL focus 110m 2.8 C lens.
    Nice. I am not complaining for $104 !!
    But bokeh is jittery, not buttery.
    Here is a boring test shot, wide open.

    Yup it is. The 150mm D is something a lot of lenses should be looking up too in all brands.

    I have to admit... as someone who likes a LOT of "butter" in my bokeh... there is something strangely appealing about the first shot you posted. Yeah, the BG is a (ok VERY) bit wild, but the drawing of the in-focus region is pretty cool... maybe "3d"?

    Lens might be fun for certain shots... I'm thinking B/W.

    I've also always thought of myself as a buttery bokeh boy but I have to agree with Shelby that there is something strangely appealing about that jittery bokeh. Not a boring test shot at all. And much to my surprise I think that Shelby's desaturated treatment tones it down perhaps a fraction too much. The lens is a total bargain for $104 -- you should be able to do some really good work with it. Thanks for broadening my horizons (although I'll continue to hate swirly bokeh).

    I do see it now. Didn't grab me until the thumbnail image appeared on my post.
    Thanks. Plenty more 110mm C lenses out there.
    Grab 'em up and play!

    oh drat. stumbled on a cheap, bargain quality 80 1.9 and bought it.
    somebody stop me please. I find all this cheap manual glass too tempting.
    will post more pics as soon as I can.

    Re: how is the mamiya 645 110mm manual focus lens?

    This is a very old thread, but here are some Mamiya 110 shots on a Pentax K-5 (effective focal length about 165mm). Bokeh differs somewhat; depends on the contrast as much as anything, I think. All at f2.8.

    Re: how is the mamiya 645 110mm manual focus lens?

    This is the N version of the 110/2.8 at f/4. With extension tube #1, IIRC.

    The in-focus sharpness is excellent and I quite like the falloff and bokeh.

    In astro work at f2.8, in terms of aberrations, the 110mm is better than my 80/1.9 wide open, not quite as good as my 80/1.9 at f2.8, and further behind my 200/2.8 APO at f2.8. The field is extraordinarily flat, but there's a little axial chromatic, and coma/oblique spherical off axis - classic fast Planar-type behaviour.

    Ray



    And the obligatory 100% crop of the eye area:

    $102? You were ripped off, Eric! Got my N version for $55 on ebay.
