    300 mm Plasmats

    I have been thinking about getting a 300 mm plasmat for use on my 8x10 field camera.

    I know they are big as I already have a 360.

    But they don't seem to come up very often. Only a few bargain condition lenses at KEH, uncommon on EBay.

    I am not fishing for offers but I just wonder where they are? Were they uncommon in the heyday? I see a lot more 305 G-Clarons and Nikkor M's, Apo-Ronars, etc.

    Re: 300 mm Plasmats

    I forgot to ask if I am crazy for wanting one?

    I print at 16x20, usually landscapes, buildings, abstracts. Sometimes close enough for bellows compensation but no macro or table top stuff. I have a 305 G Claron and a 300 Nikkor M (not enough image circle for me). So I am really asking if I would see any difference in contrast or sharpness in a 16x20 print, TMY2 in Xtol.

    My 305 G-Claron appears sharper to me than a Caltar II-N I owned briefly. Only one anecdotal data point there.

    I have a Fujinon-W 300mm in a Copal 3 shutter. Its big, its heavy, and gets used a lot . Oh, its tack sharp too!

    Ebay has a LOT of 300mm Plasmat lenses, look at all the Sironar's, Fujinons, Nikkors, Sironar's,etc... LOTS to choose from .

    I don't think you're crazy for wanting one - I have a 300mm Symmar, and I think it's great!

    No, I don't think you will see much difference on a 2x enlargement. Some difference in contrast and/or tonality perhaps, but sharpness? Only difference you'll see is in DoF if you shoot wide open.

    The Fujinon 300A is a plasmat, but opens to f/9 only. It's small and light compared to the other plasmats. It takes 55mm filters. It's nasty sharp and covers 11x14.

    Jerold,

    I'll second Daniel's 300 Fuji-W. I bought one from KEH (bargain - no lens caps)) for $295 and it is sharp as a tack, but big. It is much easier to focus than my 300f9 Nikkor and huge coverage on my 8x10. I have printed a few 36x45 prints (inkjet) from an 8x10 transparency and it blows me away. Whether you would see the difference between the plasmat and you Nikkor or G Claron, I don't know, but my "guess" would be no.

    Having purchased several "bargain" lenses from Keh, I would not hesitate if the price is right. So far, I have always received lenses that are more than "bargain" rated as far as I am concerned. Jim

    Re: 300 mm Plasmats

    I was just looking through my 1933 edition of Das Deutsche Lichtbild and came across an ad for Myer Plasmat. Here's what it said:

    Ein Spharo-Achromat hochster Vollendung! Liefert naturwahre Bilder von unver=gleichlicher Plastik u. Tiefenwirkung!

    So, there you go. There's also an ad for Rodenstock Imagon among other things.

    Hard to find? My impression is that 300mm plasmats are the most common 8x10 lens out there. Here is my lens, the extra weight does not seem to be a problem when hauling it around.

    Attractive camera by the way. What brand is that?
