Hello form Calgary - new to LF (already have a question!)

[Tin Can]

I see you do have a location, i missed that...

I wear glasses, but they seldom work.

Sorry!

Welcome to large format! I'm just a ways up north of you in Whitehorse.

With Taija71A's help I think I've figured it out.

After taking a closer inspection at the rear lens element and comparing it with photos of other Fujinon W 150mm's, I realize now that my lens was shipped with the wrong rear element! It looks like it may be the rear element of the Fujinon W 150mm f5.6 (instead of the f6.3), or maybe another lens.

Here's my lens with the rear element


here's another fujinon W 150mm f6.3 showing a much smaller rear element


and here's a fujinon W 150mm f5.6 showing a rear element very similar to mine


anyone have a spare rear element for a fujinon 150mm f6.3?

Thank-you for the kind words Patrick. Greatly appreciated!
It was a real pleasure speaking with you. Glad to be of some assistance...

Best regards, -Tim.

Patrick,

It would seem that the lens is to blame. If you can get your hands on another, know-to-work, lens and try it out you can definitively eliminate camera problems.

If your lens was sold to you by a reputable dealer/private party, they should take it back if it is indeed defective or a "Frankenlens" mishmash of unmatched elements.

FWIW, the Fuji 150mm f/6.3 lenses were four element lenses (in three groups) while the f/5.6 150s are plasmats, i.e. six elements in four or six groups. The plasmats are generally better and have more coverage.


Best,

Doremus
