Sigma f2.8 14mm EX lens.

I am led to believe that production of this lens is soon to be or may already discontinued.

Apparently the math related to costs of unit production versus number of items selling, suggest it worthwhile not to continue making it.

So if you are hoping to wait awhile to buy this lens secondhand or for a price drop, maybe this is the time to buy before it disappears.

I can vouch for its usefulness on my AGUS35 based setup. How it performs on different relay designs I cannot offer any valid opinion.

i have a dslr, and if this is a modern lens i would not recommend this, as you would have no manual control over aperture, atleast not without quite alot of work (as it is electronicaly controlled).

i am unsure of the importance to you, but it has reasonable optics on a dslr anyway if you wish to use it.

Tim, there are products sold that control the lens without using a camera body.

The DIY and very inexpensive way of doing it is to adapt the important bits out of a camera body.

This lens has a toe in both camps. It is specified as a film and DSLR camera lens. It is manually controllable for aperture and focus but also is motorised and has ability to be managed by a film camera or DSLR automatically.

It has a useful field of view but care has to be taken to protect the front element which is almost hemispherical and protrudes beyond the cutaway sunshade.

Mandatory best practice is lens covers on at all times unless actually shooting and side cover tube on when initially scoping the shot.
