To 6-Bit code a 90mm or not?

[VINCET]

Is it worth having 6-bit coding on lens like the 90mm Elmarit? Besides the Exif info, any big benefit? If I remember correctly, having 6-bit info on wide lenses is a must have.

not really worth it above 50mm

Haven't seen much if any difference. I set the lens type code just to get focal length into the EXIF.

At 90mm, the biggest reason is for EXIF identification.

Good to know. I guess I will save myself some money and not do this.

Thanks

I use one of the User Profiles for my 90mm and have used the manual lens selection to my 90's code.

There are flange replacements available on Ebay for $20-40 USD. I bought one of these a couple years back and it worked out fine. There are different configuration for the screws, make sure you get the right one for your lens. For the $20, it's worth a shot (IMO).

I actually just broke down and ordered one of those eBay flanges for my 90... Yeah, supposedly they work okay. Should be here any day... I'll report back. I've bought those cheap LTM/M adapters off eBay before that were codeable; but I didn't care for them and returned them.

Ironically, just today I completely overhauled the Leica Lens Codes page to include some new lenses and a lot more info.

I think its well worth it for the EXIF info if all your other lenses are coded, otherwise leave it. But I have coded mine with a Dremel which works perfectly, and also used the Chinese replacement flange just to see how efficient they are. And they work very well indeed. Make sure you have the correct size screwdriver (an '00') and it takes just a few minutes to swap them over. Use black paint, not a marker pen, to code, and you don't need the white marks.

I had my 90 Elmarit-M coded so I could sort in Lightroom, but as others have said this is really the only reason to code a lens longer than 50mm.
