The g claron is a 6 element plasmat, with coverage of about 80 degrees
stopped down. The repro claron is a 4 element lens, much like the
artar or apo ronar. They have much less coverage, the artar as a rule
of thumb has an image circle roughly equal to its focal length. I
would expect the repro claron to be in the same category.

I had a 270WA a while back which I played with on my 8x10, although I
didn't expose any film. The coverage didn't seem all that great,I have
heard it is no better than a regular G claron. The lens is a 4 element
design, as opposed to the 6 element G claron. The Schneider catalogue
lists coverage @ 72 degrees. The 210 & 240 WA G clarons are listed @
80 degrees. The Kowa Graphic 270mm would probably be a much
better choice. I have a 210 Kowa, and it covers 8x10 with maximum rise
available on a Deardorff (about 70 mm )

I had an Elwood 8x10 which I was pleased with. The only reason I sold
it was because I rescued a Saltzman on the way to the dump.( the
Elwood seemed big until I had to wrestle the 800lb Saltzman into the
darkroom )An enlarger is a simple device, as long as it is aligned,
has a good lens and a suitable light source, it will produce excellent
results. If you don't plan on printing negatives larger than 4x5
though, you may be better off with a 4x5 enlarger, which tend to be
much smaller.

I use the Nikkor 360/500/720 set, and this makes sense to me because
it is more versatile than a single focal length. I haven't used Fuji T
lenses, but someone I know who has used both said he found the Nikkor
slightly better.

i use the Fuji 300&450 lenses,both are superb, although I haven't used
the Nikkor. 8x10 coverage with the 300 is adequate, but doesn't allow
too much movement before the corners go soft. I picked up a 305 G
claron in barrel for a song, so I just exchange elements with the
300 fuji for 8x10. The 305 G claron will cover 8x20.

Although Fuji has discontinued production of the 240A f9, used ones
are available. I have this lens, it is extremely sharp all the way
from macro to infinity, covers 11x14 @f45, is in a copal 0 shutter,
and weighs only 225 gms.

Tmax films have excellent reciprocity characteristics and fine grain.
They are very sensitive to time/temperature variations in
processing, not that this is a problem if you use good technique. One
fatal flaw I have discovered, however, is that they produce horrendous
newton rings when used with glass negative carriers. This can
ordinarily be eliminated by using anti newton glass on the top (base)
side, but Tmax, unlike other films, also produces newton rings on the
emulsion side. Agfa apx 100 produces no rings, even without AN glass.
If you use a glassless carrier, all this is irrelevant. I use 5x7 and
8x10 mostly, and my Saltzman 10x10 enlarger uses a glass carrier.
Nearly all 8x10 enlargers have glass carriers, as film flatness
becomes a problem for negatives this large.

I have 19" and 24" red dot artars for 8x10. I bought them in barrel, and had them mounted in used copal 3 shutters which I has bought. I live in Canada, and they cost around $200 each to have done here. I believe the aperture scale also cost extra, since my shutters were the older type, and new scales had to be engraved, rather than purchased. They are extremely good lenses, indistinguishable in performance from equivalent Nikkor or Fuji lenses. Image circle would be less, which may be a factor depending on what format you use.

I have owned a 9.5 inch golden dagor for a number of years. I have decided to sell it, only because I have a Fuji 240 f9 lens also, which does essentially the same thing. The Fuji has a hair more contrast, in a test enlarged 9 times. For 8x10 work, even enlargements, you would not notice a difference in quality. One advantage of the Dagor is a very large image circle, I believe between 85 and 90 degrees. Another excellent lens in this focal length is the Schneider G claron. It produces a much larger image circle than Schneider advertises.

Agfa actually did manufacture APX 25 in sheet film, 4x5 at least, until quite recently. I suppose they discontinued because of lack of demand. Kodak will manufacture virtually any size of film on special order, but you generally have to buy a very large quantity. Perhaps if enough of us prevailed upon Agfa, they would re-introduce it.

Coverage of Graphic Kowa 150 mm f9 lens
in Large Format
Posted
I got one in a barrel, it mounts in a #1 shutter. It just clips the corners on 8x10, so might
be OK for 4x10. I also have the 210, it has a wider angle of coverage than the 150 as the
construction is different. Both are extremely sharp, the lens is f9 in barrel but I believe it is
faster in a shutter.
