In Topic: Full Frame SLR wide angle corrector port tests

Today, 02:52 AM

Hi Alex

 

So what is the design type (Ivanoff corrector)?.

 

If so from my reading its probably limited to about 90 degree fov anyway (20mm on FF).

 

Or is it aspheric (if so I'd have expected it to be matched to a specific lens).

 

Or is it a compound optic (doublets)?

 

I'm interested to hear anything more (when was it designed and what was its original purpose.

 

FWIW Leica (Elcan) designed some interesting ports but all were prototype or very low volume  (military) production, and being Leica are ludicrously price collectables today). One was even incorporated into a 35mm camera housing and marked as '90 degrees' rather than the focal length. The technology is probably quite old (I have some papers showing complex correctors for any lens up to about 90 degree FOV) but mass production of a viable system has never seemed to have been economically possible.


In Topic: Do 15mm's need servicing?

10 December 2014 - 11:47 AM

'O' rings can deform over time and may dry out too and be a point of potential flooding. And any salt not washed out can case corrosion too of course. Its a tricky one because I have a suspicion that 15mms may be awkward to strip down and some spares may be difficult to get, but I can't remember whether this affects the first or second version, or both. Try www.aquaphot.com (UK) as Kevin knows his Nikonos gear and I would happily take his advice and entrust him to service anything Nikonos.


In Topic: Getty invite

27 October 2014 - 12:57 AM

Getty demand exclusivity but DO sell. To me they appear to see images as a commodity and sell accordingly - its not a particularly rewarding way of seeing images sell. I do have some images with them following their purchases of various agencies but I do struggle to submit new stuff because of their exclusivity clause and way they sell.

Actually I may just keep this housing and sell my original Canon 5D Mk1 housing complete with the camera - I could supply it as a ready to go outfit so if anyone is interested pm me.


Hi Paul,

have you got a standard view finder for sale if so what is the price, as I may be interested for splits as I find it hard with the S45.

regards,

Andy.
