E-mount Lenses for Infrared (IR) on NEX cameras

I've been generally unhappy with AF lenses for infrared. I am OCD about no hotspots, though, as in really, really fussy. The only lens I use much for infrared, other than old vintage lenses which are usually very good (so long as the look good on non infrared cameras too) is the Sigma 30mm 2.8 lens. The 18-55 and 50-210 lenses aren't too bad as long as you watch that you aren't using deep infrared filter.

My favorite lens is normally the 35mm Zeiss 2.8, but for infrared it is nearly useless, sadly.

I'm very much hoping that Minolta A-mount glass from the 80s is going to be my salvation in this regard, as I am happy with the LA-EA4 adapter. I just received an LAEA-1 adapter too, and will use it as an extra adapter for lenses I intend to only use with manual focus, just to get the aperture control.

@ eagleeye
I like a lot the results i get from e 10-18 , 55-210 and 50 f1.8, i think they are very good lenses for both ir and normal photography.

Also you will find many information about a mount lenses here : Lenses and unmodified cameras for Infrared (IR)

What filter are you using ?
At 720nm mild hot spot starts at f5.6 (i correct the first post also, was f11)little annoying after 6.3 but nothing you can't deal

Have you tried 24mm f1.8 or 28mm f2 ? I 'm going to buy one of these (in the next 1-2 months) and i would like to shoot also ir with one of them.

Thanks nandbytes, i ' m really appreciated

@nandbytes: I can confirm your observation w.r.t. FE35/2.8: from F5.6 onwards not really usable as hot spot is quite distinct; ok till F4 only

Not in a position to recommend any E-mount lenses, as my IR camera is a converted Maxxam 7D. The lens that I use on this camera is the Minolta AF 24/2.8. It is excellent, no hot spots at all. However, I don't use any filters with the modified sensor, so cannot say if results will be the same when using any filtration on an un-modified body.
