Zone VI and 15 inch Tele Optar..Experience and opinion?

[Drew Bedo]

am currently using an early Zone VI (Wista Mfg) in 4x5 with about 12'' max bellows draw. My current focal lengths are: 90mm, 150mm and 210mm. I am interested in a Wollensak 15 inch Tele-Optar (380mm). I am aware of the issues of weight and coverage. So then; What else mis there to be considered?

I can tell you that I have used one on a Shen Hao 4X5. There seems to be some disagreement on the coverage of this lens, some people say it covers 5X7 some that it barely covers 4X5, my experience makes me feel more like 5X7. I can focus down t about 9 feet with the Shen Hao.

Thanks Skiorzen...SD then, nine feet: How much bellows extension does it take to get to nione feet? How is compensation for bellows extension handled for a lense of this type?

I have a wolly 15" tele on a 5x7 aerial camera and it covers the format, but the thought of using it on view camera while attempting to take advantage of movements gives me a headache!

I couldn't remember just how much extension the Shen Hao had so that's why I left that out :-). Anyway Nine feet was with maximum extension without doing weird things to the front standard (I front tilt and rise to get a couple more inches, lens is too heavy for that IMHO) so about 12 in.

i've been using one in a barrel with a speed graphic for years.
if you use filters, it might be something to think about ...
the diameter of the front is quite large.

You might find additional information in the post on this same subject done less than an hour before you posted.

Be aware however that the 15" f5.6 tele-optar/tele-raptar is a big, heavy, chunk of glass. Shutter speeds are limited to 1/50th due to the large press shutter.

I have no experience with a wista, but you may need extra support for the front standard.

I have one of those lenses, and I have a Zone VI, but mine is a later version, the one made in Vermont. On my Zone VI, no problem. However, that lens is too large & heavy for my Tachihara.

I do not know how big or heavy (or light) your Zone VI, but if it is "Tachiara sized", not a good idea. If it is heavier, like mine, will work fine

hope that helps.

Joseph,

Thanks for the information regarding my camera (Vermont Zone VI) and the 15" Tele-Optar should I ever want a longer lens.

Cheers!
