View Full Version : ZM 21/4,5 Biogon and the 25mm hood
Can anybody confirm that this hood does not vignette on the 21 Biogon ? I've seen in Tom Abrahamsson's review that he wanted to give it a try, but there was no confirmation as to the result. My Biogon has arrived this morning, and I will be off in the afternoon for a short trip, so I have no time for testing this myself. Any experience will be appreciated. Thanks.
Sorry about not confirming that the 25/2.8 hood does NOT vignet on the 21f4.5. I tried both hoods (the 21/2.8 hood and the 25/2,8 hood). Neither one shows any traces of vignetting. I keep the 25f2.8 hood on the f4.5 as this lens is more or less "welded" on to the R4M and the 21/2,8 hoods blocks the lower right hand corner quite a bit. The 25 is still visible in the finder but I find that I can 'shoot" around that one.
Enjoy the lens, it is a great addition to any lens "cache".
I have been promised a 18f4 in the coming week and it will be interesting to run the two side by side.
Hmm! another project coming up "Does three millimeter make a difference" Try the 12/15/18/21/25/28 as a wide package.
Tom, I will be very interested in your ZM 18/4 results! I assume you will post some to the M-mount group on flickr?
good cheer, Thomas
