My M 8.2 arrives tomorrow.

 

I currently have the following lenses,

 

Leitz Summicron f2 50mm version IV

 

Zeiss Biogon f2.8 25mm ZM

 

Will i need any IR lenses when shooting black colours in incandescent light?

 

 

If so what do forum members recomend.

 

Many thanks.

Congratulations on the M8.2!

 

Yes, basically the camera requires the UV/IR-Cut filter with all lenses.

 

Leica's own brand is good; so are the 486s from B+W. And there are other brands as well.

 

Remember, these go on the lens and stay there. They become a part of the optical system with the M8 and M8.2, so don't scrimp. :)

The ir effects most colors under all lighting, but black is most recognizable.The purple black is easily repaired in ACR. Use the local adjustment tool with auto masking turned on and desaturate. Takes 15 sec to do. Other colors you need pretty good photoshop skill.

 

Buy the B+W 486 ir/uv cut filter and all the issues go away, but you get new ones, cyan/green edges. Cornerfix is a repair but not perfect. Best to code the lenses and let the camera software correct the problem as best it can which will not be perfect. Use corner fix to touch it up.

 

Your 50 will not make off color corners, the 25 will. Make sure you get a 25 that brings up 35/24 frame lines and it has the groove in the mount flange to accept manual coding. Early ones will not meet these specs.

 

Took me 4 months to sort out all the issues and get colors as correct and uniform as I get from my Nikons.

 

I coded all my old lenses with replacement mounts from jinfinance on Ebay. Takes 4 weeks via China Post to USA. These also are not perfect, but you can send the lenses to Leica USA and $240 , but the will not touch the Zeiss.

 

Good luck

If you are a B&W fan the filters will be a detriment.

You will get more information in your shadows without the filters.

 

I have found the old 5o lux does need a bit of tweaking for the cyan edges, as said corner fix is great.

 

Do get a uv black filter for experimenting with the ultra violet capabilities of this camera, you will be enchanted.

Flamez, welcome to the forum!

I assume you are referring to filters rather than lenses in the above quotation. All lenses benefit from their use on M8 or M8.2 camera lenses if you not not want to risk certain synthetic black fabrics taking on a magenta hue. Also consider getting your lenses coded for recognition in camera. This is important for lenses wider than normal, but also aids identification from your EXIF data in post processing.

Do, do get an IR filter, Heloipan do a good range of them at a fair price

Set the colour temp to 2000, ISO to 320, shoot in RAW - and you've got digital IR photography - handheld on a good bright day - dead easy.

Welcome to the forum and enjoy!

We need to distinguish between IR-Cut filters (the kind the M8 needs to avoid image contamination) and IR-Pass filters (usually just called 'IR filters'). The latter are designed to block a big part of the visible spectrum but transmit IR. That's what you use for IR photos, and we're lucky that the M8 is such a wonderful camera when shooting in that part of the spectrum.

Many thanks have ordered B&W 39mm MRC F PRO digital uv/ir block 486.

 

The blurb says specifically for M8

Just a quick question, did you mean colour temperature in Photoshop/LR etc? Or on the camera?

Shooting raw, the color temperature on the camera is uninteresting, it is a good idea to shoot raw+B&W jpg, to get a nice readable thumbnail into your raw converter. Helps with selecting.

Yep - that is a good filter. Now get some Superglue to affix it to your lens permanently:D

Seriously - you'll see a vast difference in color rendition.

 

My advice. Don't superglue anything. If you can't remember to shoot with the filter on, then there is a real problem with the shooter. No offense jaapv. If the only camera you have for your M mount lenses is the M8, just leave the filter on. No need to glue it. Glue? What if you want to sell that lens to get another?

It is highly adviseable to use the UV/IR Cut filter when shooting with the M8/.2, since certain black fabrics will change in colour. However if you think that it's not an issue then by all means don't use it. I have a friend who doesn't use any UVIR filters and he's still happy with the results. :)

Err - you should visit the nearest joke-detector repair shop.
