Anybody know whether long lenses (eg 300mm  Symmar-Sironar- Xenar) are
inherently sharper than telephotos of similar focal length, or much more
compact in the outfit bag?  Obviously the telephoto construction is likely
to narrow the maximum field of view/movements but used with rollfilm backs
this does not much matter.
On a related point, in the UK it is possible to buy good used ApoRonars or G
Clarons about 300mm for a lot less than TeleArtons.  F9 doesn't look too dim
on the groundglass in daylight; these graphic arts lenses evidently are
corrected for close work- does this make them unsuitable for distant
subjects or do they just need stopping down?
The non-telephoto construction might necessitate an extended lens panel to
supplement the stretched bellows but this is not what concerns me.
Thanks for your comments.  Philip
