I experimented with IR photography using my Elmarit 28/2.8 on the M8. I realized that this lens appears to cause a significant hot spot under IR conditions, especially with apertures 8 and up. :(

 

Can you please share your experience with other lenses on the M8 when using for IR photography?

 

Thanks!

ASPH or pre ASPH? I have no hotspots with my pre ASPH and Hoya IR72 filter.

I'm using the CV 21mm w/B+W 093 filter on the M8. No hotspots that I can see with the CV 21. Have used the Summicron 35mm ASPH and Summicron 50mm--also no hotspots. (These are "known safe" lenses.) Need to shoot more IR: Infrared - a set on Flickr

 

Ditto on the Zeiss 25mm photo posting--love to see some.

 

Thanks,

Will

Wold be great if m8-shooters chime in on experiences with lenses working for ir-photography on the m8 (i.e., lenses without a central hot sport when using ir-filter).

 

Thanks...

I've been shooting infra-red handheld with my M8 for about 10 years and my favourite lens, which has no IR hot-spot, is the 21/2.8 Kobalux (which is also sold under the Avenon brand).

 

Before that I used the Voigtlander 35/1.2 Nokton v1 and there was no obvious hot-spot on that.  (Wide open it understandably vignettes a lot, which might be mistaken as a hot-spot at such a wide aperture but it's not.)

 

I used the Voigtlander 15/4.5 Ultra-wide Heliar v1 (LTM) for a while and it had no hot-spot but it became awkward to attach the IR filter owing to no filter thread and a fixed semi-hood.

 

The 35/3.5 Summaron has a reputation for having no IR hot-spot but I can't confirm since I haven't used it.

An example I shot handheld this week with the 21/2.8 Kobalux on my M8 with a SinghRay I-Ray filter (830 nm).

Hi!

 

So far I have tried and used a 28mm Elmarit-M ASPH (mkI) and a 50mm Summilux from 1971 with a Ø43mm original Leica filter, probably something like a R72 (+ a StepDown ring with the 28mm..), and a 21mm Elmarit-M ASPH and a 90mm Summicron (pre-ASPH) with a cheap eBay Ø55mm 950nm filter, and I have not detected any hot-spots as I can find with any of these lenses.. I haven't looked at very many photos yet, so if I see it in the future I will correct myself... ;)

 

Best regards,

Rune :)
