View Full Version : I Still Don't Get It

Can someone explain to me why I would NEED (i.e. it's absolutely necessary) six bit encoding on my lenses if I were to get an M8?

Just keep it short and sweet; no need to get into the whole "are you getting one?" thing. :D

Danke,
Dave

For the camera to recognize the focal length you attach and apply
software (color)vignetting correction. Vignetting
depends on the focal length. The pixels will loose some depth/bits in the
process.

The vignetting is more pronounced with the M8 than with other digital
cameras due to the short registration distance.

Obviously more important for wide angles.

You can probably do the same in PS since you are PS savvy.

Best,

Roland.

Dave,

The six bit coding gives you two things - lens data in the Exif and corner colour correction (cyan drift) with wide angle lenses - in theory 35 and wider, but I've found no problem with 35mm lenses on the M8, so if you shoot 35 or longer then its not really necessary. Also there is a program named cornerfix written by Sandy ?? (I think he is now a member here) which can deal with the cyan corners. If you mainly shoot B&W then no need at all really - any vignetting can be dealt with in ACR.

Thanks Gid and Roland - makes me consider... ONLY CONSIDER.. snagging an M8 at some point :D

I just didn't want to go through the hassle of getting a) new lenses or b) sending what lenses I do have (only one Leica lens really - my 50mm Lux pre-ASPH) in for encoding.

Cheers

Dave,

Recommend you try out the RD1 - great camera, more analogue and lower price of entry. If you don't like it you'll sell it easily enough.

I'll give it a shot Gid.. just worried about the old Bessa RF alignment that's all.

Not to beat a dead horse, but... all of my CV-built rangefinders have come out of alignment, including the R-D1. Once realigned by a competent repair person, they have never drifted back out of alignment, including my R-D1 which I carry around alot and which has been overseas on a long trip to Israel, too. If that first realignment doesn't bother you, you should have nothing to fear.

Additionally, you can do it yourself - really easy.

Plus, if you are not averse to handling a jeweler's screwdriver, you can have John Milich add coding pits to your lens flanges to the tune of $25 a pop + S&H. I had it done to my CV 40mm Nokton and am having it done to my CV 25mm P.

You could always invest in a bank that does a lot of sub-prime mortgages, Dave.

Thanks for this - I'm going to review this information and Phil Askey's review (to see the menus etc) and make a decision - I know if I order one locally by tomorrow I can have it for Monday :D
