wlaidlaw Posted July 7, 2007 Share #21 Posted July 7, 2007 Advertisement (gone after registration) Hi Wilson, Did you mean to address this to me? You know that I started the ball rolling with Zeiss for the alternate mount option, right? Have you seen the 21s review? Cheers, Sean Sean, I have not read all your 21 review - ashamed to admit I skipped straight to the conclusions as I already had the Biogon 21 and very happy with it (Wilson to headmaster's study). Don't tell me you have managed to get Zeiss to do the sensible thing and offer the 28/90 bayonet on the B21? Now for an encore if can you get them to change the horrible lens caps, then it will be the full bouquet. Wilson Link to post Share on other sites More sharing options...

stunsworth Posted July 7, 2007 Share #22 Posted July 7, 2007 Fahim, as far as I'm aware Cameraquest doesn't provide any coding services. However if you get a thread mount version of this lens you'll need a thread to M adaptor, and it's possible to buy one of those from John Milch (sp?) that has the six small pits milled into it. You'll then be able to code the adaptor yourself. Link to post Share on other sites More sharing options...

But does that mean that for 6 bit coding i need to get thread mount lenses only? either from voigtlander or zeiss. seems to me these guys are producing m mount lenses now..so how does one go about coding these? I realize I might be testing your patience, but your advice is greatly appreciated. Regards. Link to post Share on other sites More sharing options...
stunsworth Posted July 7, 2007 Share #24 Posted July 7, 2007 No problem Fahim, to code the M mount lenses you need to either use a suitable black pen and a template - see here for codes and a link to a template... Leica M8 Lens Codes or alternatively you can remove the mount and send it to John for milling. This of course being at your own risk (the removal of the mount that is :-) Link to post Share on other sites More sharing options...

Cindy Flood Posted July 7, 2007 Share #27 Posted July 7, 2007 Advertisement (gone after registration) Fahim, If you buy a CV screwmount wide angle lens from Cameraquest, then don't buy the adapter from them. Purchase the adapter from John Milich (do a search here for his username and email him.) The adapter will come with the indentations for the code. Buy small bottles of white and black nail polish or model paint and a small brush. Look up the code here: Leica M8 Lens Codes (Carsten has kindly provided them.) Paint in the white and black codes one "pit" at a time. Take an old credit card and pull it toward you across the "pit" to remove the extra. Let each dry before painting the next. It is really easy to code. Link to post Share on other sites More sharing options...
Samir Jahjah Posted July 7, 2007 Share #28 Posted July 7, 2007 "hello, "4. is six bit encoding required for all lenses? or just with infra-red filters? what if i only do bw imaging? what if i do not do six-bit coding?" If one is using IR-cut filters, coding is very helpful for 35-40 mm and wider lenses. It also helps with vignetting but that correction isn't always needed. If you only shoot in BW, you can ignore coding and filters if you like. I myself do not use the filters for BW work. If you work in color (with the filters) you don't really need the coding for 50 mm and longer lenses. Cheers, Sean Sean, Are the IR filter only useful when photographing dark/black fabrics in certain lightng condition or do their improve the overall color? I have noticed that most of my in-door pictures have a pink cast that white-balance adjustments cannot eliminate. Would IR filter be helpful to get rid of the pink cast?

AGeoJO Posted July 7, 2007 Share #29 Posted July 7, 2007 Hi Josh, ...With the caveat that the 21 mm effective field of view on the M8 is significantly wider than the full finder area. The full finder is actually close to the EFOV of a 24 on the M8. In other words, I use a 28 mm external finder for a 21. Cheers, Sean Sean, after I posted my previous reply, I pulled my camera and 21mm out and did another test since I did the test quite sometime ago and don't exactly remember the results. Well, the age, you know . Actually, the entire viewfinder is a tad wider than the angle of view of my 21mm Elmarit ASPH. I am not wearing glasses however (thank you, lasik!) and if I peer through the viewfinder without any hindrance of glasses, either sideways and/or up and down, I got quite a bit more from the viewfinder than what the 21mm lens gives me. I understand that there could be a focal length variation from brand to brand or even from copy to copy but with mine, I don't hesitate to use the viewfinder as my frame line.

Joshua, I agree - it's the same with the Biogon 21. You need to peer round the edges of the viewfinder a bit to get a true idea of what you will get. However I am still not using an external viewfinder even with a 16mm semi-fisheye and I find I can manage. If I remember to use my right eye and keep my left open it helps but like many other people, even thought I am right handed, I have a left master eye, so that is the eye which naturally finds its way to the viewfinder.

sean_reid Posted July 7, 2007 Share #33 Posted July 7, 2007 Sean, you are right, the entire viewfinder is indeed smaller than the view angle of a 21mm lens. However, the 24mm is well within the viewfinder itself and if you are not wearing glasses you can actually peer sideways into that and get a little more. While I agree that the angle of view of the 21mm is wider but the difference is not significant, not to my eyes, at least. I tested this before and really not that much of a difference in actual shots. I would venture to guess ...... maybe around 22mm . It depends,in part, on the focus distance. Those 24 mm frame lines are about right at .7 meters. At further focus distances the full frame comes to be the best indicator of the 24's EFOV. For my purposes, the full frame is too tight for a 21. Others may not mind that the view will be so conservative. Cheers, Sean Link to post Share on other sites More sharing options...

Wilson Hi Wilson, Last September I had a phone conference with them and urged them to offer alternate bayonets for the 21 and 25 (to better suit the M8). They now offer this as an optional service.

Thanks Samir IR can affect pictures made of all kinds of subjects. Dark textiles are just the tip of the iceberg. So yes, for most subjects, the IR filter will be very helpful if you are working in color. Cheers, Sean Link to post Share on other sites More sharing options...

The angle of view of my lens is actually quite a bit narrower than the entire vewfinder of the M8. Wilson (wlaidlaw) checked his 21mm Biogon, and that lens' angle of view yields approximately the same results. The entire viewfinder actually is probably closer to the angle of view of a 19 or at least a 20mm lens, just FYI. Link to post Share on other sites More sharing options...
fursan Posted July 8, 2007 Author Share #40 Posted July 8, 2007 Which ones? Cheers, Sean I need a 21mm. thinking about the biogon 21/2.8 but i am moving to rf for less bulk and the c biogon 21/4.5 seems inviting. Regards. Link to post Share on other sites More sharing options...
