Regarding the UV/IR filter

Recommended Posts

Advertisement (gone after registration)

I have a chance to get an M8.2 for a ridiculously low price (it's been cosmetically modified, and in Japan that actually devalues it, which is good for potential buyers). I've checked it out and it seems to work fine; the RF seems to be OK, no weird stains on the screen, and so on. The shop also has a very nice example of a Voigtlander 50mm 1.2 lens, and together with the camera it's well within my definition of "non-reckless affordable".

I've been looking around for a good UV/IR filter, and I've come across several variants. One of them is called a "Hot Mirror filter". It's still advertised as "UV / IR cut".

Is there something different about these, or is it just a name? I don't mind paying a bit for a decent UV/IR. If anyone has any particular recommendations (or suggestions to avoid), I'd gladly hear them.

Thanks in advance!

You need a UV/IR cut filter. B&W makes very good ones less expensive than Leica.

Hot mirror means the same as IR-cut or UV/IR cut when the filter blocks some UV as well. It is a filter blocking infrared light mainly, which is what your M8.2 needs given that its own IR-cut filter is not efficient enough. Well known issue of M8 and M8.2 cameras which in turn have a very thin sensor stack (0.5mm) providing an acutance that very few cameras can compete with. 
Tiffen, Schneider ("B+W"), Hoya, Heliopan, Rocolax and other brands sell those filters but i prefer Leica's personally because they have an internal filter thread allowing to stack another filter or a screw-in hood into them if needed. 
BTW you may wish to register your camera on the Leica site before ordering the filter in which case, with a bit (lot) of luck, Leica could send you one filter for free even if your camera is second hand. Déjà vu on the LUF.

I realize that your CV lens has 52mm filters and that Leica did not sell UV/IR filters in that diameter if memory serves sorry.

Don't forget that your lens will effectively be a 67 mm lens on the M8.2 thanks to the 1.3 crop factor of the APS-h sensor.

Yes, actually that's a plus for me as I tend to generally see in short telephoto terms. 67 is also in portrait territory. But thanks for the reminder anyway.

Thanks for all the responses. I haven't bitten the bullet yet; classic heart (I love the RF experience, but don't shoot film, and this particular M8.2 is actually going for less than the Epson RD-1 second hand here) vs head (If an important part breaks, you are buggered) battle in progress.

Mind you, there's a Leica store / boutique / poser's emporium 😉 where I live, so I'm pretty sure they could handle things like RF calibration if and when that goes off - assuming they service cameras that weren't purchased directly from them...

If the price is in your budget, go for it and you may find UV/IR filter later.

While waiting, experience the infamous B&W from M8 without UV/IR filter.

If you like it you even may not need/want UV/IR filter.

 

this is without UV/IR filter (I accept the "weird colors" in artificial lighting)

Matter of tastes ;)

Unfortunately, it is virtually impossible to correct in postprocessing.... I would involve layer masks, LAB technique, and blending masks with split sliders.

What is it after photoshopping? 

For me NOT possible to post-processing,

so use one real UV/IR filter when in mood with plenty of IR like landscape or inside.

This is example for which I must put UV/IR filter on the Noctilux v I (at that time it must be Series VIII for 1.2/50 I tested in the shop)
