Bo_Lorentzen Posted March 15, 2009 Share #1 Posted March 15, 2009 Advertisement (gone after registration) At PMA I had a chance to chat for a while with the Zeiss guys, and fondle a bunch of ZM lenses... nice stuff really. I have been bemoaning the poor fit of the lens-hood to the 1.3 crop factor image when using the M8. (naturally the lens-hood is perfect on my M6) And mentioned that it would be nice to have a line of more aggressive lens-hoods for M8 users. after thinking for a moment the Zeiss guy pulled out a 50mm and popped the hood on my 28mm... we did a couple of test shots and it fits perfectly. Well, the hood arrived, and yesterday I shot a few quick exposures, each with and without the 50mm hood on the 28mm biogon. Result, while not entirely scientific, is pretty clear, the 28mm 2.8 Biogon does vignette on the M8, however there is no difference with or without the cs50 lenshood. as this hood is far more agressive than the normal lens hood for this lens designed for full-frame use, the cs50 hood will do a significant better job a reducing flare and protecting contrast when the lens is used on a M8 (or a epson RD for that matter) In other words if you own a 28mm biogon - you should order a cs50 lenshood for it.

anfrve Posted March 16, 2009 Share #2 Posted March 16, 2009 Hello, do you screw on or mount it with the bayonet ? i'm looking for a lens shade with 46 thread mount...fo my 35 summilux Link to post Share on other sites More sharing options...
Bo_Lorentzen Posted March 16, 2009 Author Share #3 Posted March 16, 2009 Hello Anfrve, The Zeiss lenses have a bayonet mount for the lens-hood. But when I was looking for a longer hood I also ran into quite a few general hood solutions, arranged in category wide, normal and tele, this was a seller on ebay and it seemed that almost all filter sizes were available, the style were slotted hoots exactly like the zeiss lens-hood. .

Printmaker Posted March 16, 2009 Share #8 Posted March 16, 2009 Just curious... how much of the viewfinder is blocked using the Biogon 28 with the hood designed for the 50 /1.5? Tom Link to post Share on other sites More sharing options...
Bo_Lorentzen Posted March 16, 2009 Author Share #9 Posted March 16, 2009 Tom, Its pretty much the same, the diameter is the same but the tube is longer, because the hood is slotted and angled, notice the front it narrower than the rear, so the hood is the same amount of obstruction as the original hood. .

Printmaker Posted March 16, 2009 Share #10 Posted March 16, 2009 Thanks Bo! In other words... about the same as a 28 Summicron, about the same as a 28 Elmarit IV and a little bit more than an Elmarit ASPH with their hoods. Tom Link to post Share on other sites More sharing options...
kully Posted July 8, 2009 Share #11 Posted July 8, 2009 Thanks for posting this Bo, I have a ZM 28/2.8 and also thought the standard hood was much too wide. Well, I took your advice and ordered a Zeiss hood for the 50/1.5 and it is exactly as you say - no vignetting difference between on and off. I find it odd that there is little said about the Zeiss 28mm on the internet. Cheers, kully Link to post Share on other sites More sharing options...
jaapv Posted July 8, 2009 Share #12 Posted July 8, 2009 It is the same with the Biogon 21/2.8 - I use it with the Biogon 28 hood Link to post Share on other sites More sharing options...

Bo_Lorentzen Posted July 8, 2009 Author Share #14 Posted July 8, 2009 Hello Kully, Yeah its really odd, I love my 28 biogon, its razor sharp and a very good lens really in every way. maybe there is so little written about it because it is so "shockingly free of problems" and just do what it is expected to do. maybe.? Brian, there should definately be no vignetting with the normal hood, the interesting part is that the 50mm hood also do not vignette, meaning you can use a tighter hood in environments with strong light sources. .

thompsonkirk Posted July 9, 2009 Share #15 Posted July 9, 2009 Like Jaap, I use the 28mm lens hood for the 21 f2.8 Biogon - actually it's intended for both 25 & 28. It's a very shallow hood but nevertheless does a good bit of work. I sometimes had glob-like flare spots without it. Kirk Link to post Share on other sites More sharing options...
