it will be much more expensive an 8x10 model for 150 to 300mm lens?
it could be possible to construct an 8x10 for 600mm tele lens ?
65mm
90mm

Even though I am basically a 5x7 oriented human at $100 I am good for two. One as is and one to frankencamera into a 5x7 a la struan's method
Best of luck with this endeavour!

Wow, I didn't realize the 58mm was a retrofocus design. That's great news! The front of our camera happens to be exactly 70.5mm before the focus collar. Hmm... (goes off to use CAD)
OMG 58mm version! If it was a simple enough job to convert it from 90 to 58 that would be awesome... Even if the 58mm setup was bang on hyperfocal focused and had to be shot stopped down to F/22 or further to achieve total sharpness. It would be amazing!

That's not what Ben implied. The implication is that a 65mm version could also be used with the 58.Originally Posted by alexn

I drafted up a lensboard that fits where the helical normally goes... The 90 will ship assembled, but we could ship a 65 version with the lensboard unattached.
I put the nominal FFD at 70.7mm for the lensboard, which is basically infinity for the 65/8 plus 0.2mm, a conservative hyperfocal. If you want a closer hyperfocal distance for the 65, you can shim it forward. If you have the 58mm, you can shim the inside of the lensboard to bring it back to 69.3mm, or wherever you want it.
So hope lives for a 65mm version!
Ben, congrats on a great looking bit of kit. +1 for 90mm.
I'll be watching closely to see where this goes. keen to buy one when they're ready.
Will you ship international?
I'm new to LF. Will this work with all 90mm LF lenses? are there specific lenses which will be more suitable?
Cheers

... I just re-read the thread and found the bit on page 13 about f/6.8 optar and angulon lenses.... so answered my own question.
So, no helical on the 65 version?
Rick "not always a fan of hyperfocal focusing" Denney
Probably not to start... There are way more 90s out there than 65s, so the market is much smaller. If we sell a zillion 90s, it would certainly make me rethink things. But keep in mind that 65 is quite wide—the equivalent of 17mm in 135, so it should be pretty easy to get a good hyperfocal distance that covers 10 feet to infinity.
