jazzwave Posted July 31, 2011 Share #1 Â Posted July 31, 2011 Advertisement (gone after registration) I'm looking wide lens to joint with my 50mm for M8 and M4-P. Â Due to tight budget, I consider Voigt Skopar 21/4 or 25/4, I believe these lens have similar design. Â From perspective view which one do you prefer?

Holybasil Posted July 31, 2011 Share #2 Â Posted July 31, 2011 If you want wide, go for the 21/4. Be aware of cyan corners though. Link to post Share on other sites More sharing options...
!Nomad64 Posted July 31, 2011 Share #3  Posted July 31, 2011 There's little difference in terms of angle of view between a 21 (92°) and a 24 (84°) and therefore there's little difference in terms of perspective. Unless you think you'll want the extra 8°, with the M8 you might want go for the 24/25 as you won't need the external viewfinder. With the M8 I made the very same choice and my kit was the CV 25/4 (until it was replaced by the Elmarit ASPH 24), 50mm and 90mm.  Hope this helps, Bruno Link to post Share on other sites More sharing options...
Snakepottery Posted July 31, 2011 Share #4  Posted July 31, 2011 I have a Zeiss 18mm which is a fabulous lens if you want a super wide. Beautifully sharp and you cam make some really interesting images. Slightly more expensive than the Voigtlander lens though and will need to buy a UV/IR and ideally, get the lens 6 bit coded. I am about to send mine off for coding next week. Costs around £70 or so but worth it. Never had a lot of success with hand coding. Andy Link to post Share on other sites More sharing options...
Islandmike Posted July 31, 2011 Share #5  Posted July 31, 2011 I have the CV 21/4 and it's a great little lens - excellent value for the money, to my mind.  As far as viewfinder is concerned, I just use the whole camera viewfinder as a good guide to field of view and get the subject right up to the edges, knowing that I have a little bit to spare.  After a while, you get a sense of how much extra will be in the photo and allow for it. Much the same as with the viewfinder guide lines for other lenses, which are only actually accurate when your eye position is precisely placed - which in my case is not often!  Cheers  Mike Link to post Share on other sites More sharing options...
scsambrook Posted July 31, 2011 Share #6 Â Posted July 31, 2011 I had a 25mm Snapshot Skopar and have a 21mm Skopar. For their prices they're very, very good indeed. I think the 21mm is slightly sharper, but the 25mm is certainly pretty close. Because the 21mm takes in a wider vield of view you get the illusion that the perspective is more exaggerated, but if you compare the same in-shot areas from both lenses you'll see the perspective is actually identical. Â I changed from the 25 to the 21 because (in order of personal importance): 1) I wanted a wider field of view - the 21 (=28 on full frame) really does takes in a good bit more than the 25 (=32 on full frame). It's more than you'd expect. 2) I had the non-rf coupled 25 and - despite a lot of what you read - you CAN miss focus at at closer ranges. 3) I couldn't see the v/f frame when I had the camera in its half-case, largely because I wear spectacles and I couldn't easily get my eye close enough to the v/f. The non-rf 25, having no rangefinder coupling cam surface, lets the rangefinder roller extend and so shifs the viewfinder frames to the closest focus position. In theory that should cause composition problems at long distances, but the v/f frames are so inaccurate that it hardly ever mattered. Â I ended up selling the 25 but keeping the separate v/f. The 25 v/f on the M8 with the 21 lens gives a pretty good indication of what's going to be in the frame. I'm keeping the 21 v/f for when I get a 15mm lens. Â You'll be pleased with the quality of either lens, I'm sure. Link to post Share on other sites More sharing options...

!Nomad64 Posted July 31, 2011 Share #9  Posted July 31, 2011 These were taken with M8 & CV25/4 v1 i.e. LTM + adapter ring, not rangefinder coupled (no crop, barring the intrinsic one of the M8 vs FF sensor):  http://www.l-camera-forum.com/leica-forum/members/52186-albums4697-picture6038.html http://www.l-camera-forum.com/leica-forum/members/52186-albums4698-picture6059.html http://www.l-camera-forum.com/leica-forum/members/52186-albums4668-picture5906.html http://www.l-camera-forum.com/leica-forum/members/52186-albums4577-picture5743.html  I have no 21mm myself, sorry.  Cheers, Bruno Link to post Share on other sites More sharing options...
AncientCityPhoto Posted August 1, 2011 Share #10 Â Posted August 1, 2011 I use the Voigtlander 21mm F/4. Â Actually, you don't "need" an external viewfinder with this lens. It is basically the entire viewfinder. So if you think just slightly beyond the 24mm lines to the edge of the viewfinder...that's the 21mm view. It's not 100% exact...but then neither are the frame lines. Haven't had a problem yet! Â The 21 has very good control over distortion and things like that. I also do not get any cyan corners or anything on the M8. I have coded as an Elmarit-M 21mm 2.8. The older version. Its just one black line. This works great for that lens. Â For a 21mm lens that I picked up for less than $300 US, I am extremely amazed and satisfied with it's performance. Link to post Share on other sites More sharing options...
Bobitybob Posted August 2, 2011 Share #11 Â Posted August 2, 2011 I've got a CV 21mm f4 which I use on my M8 and I'm happy with its performance for the price. Â One thing you may need to consider is that you have two cameras, the M8 with a crop factor making the 21mm in reality a 28mm and the M4 which is 'full frame' and would remain at 21mm. I'm not exactly sure what the relationship is between angle of view, which stays the same and focal length which is extended, but this may mean you would need an external viewfinder when you use the lens on your M4. Obviously the same would apply with the CV 25mm as well. Â Hope thats right and helpful. Link to post Share on other sites More sharing options...
Bobitybob Posted August 2, 2011 Share #12 Â Posted August 2, 2011 Further to my previous post, apparently the crop factor does indeed effect the angle of view. Therefore a 21mm does have the same or similar angle of view as a 28mm. This may well be an opportunity, dependant on which of your cameras you use! Again the same would apply to the 25mm (35 ish on the M8). Â Regards Link to post Share on other sites More sharing options...
ezc203 Posted August 2, 2011 Share #13 Â Posted August 2, 2011 I think aside from lens quality/image quality - you should really consider "shootablility". The M8 has 24/25mm framelines built-in, which will make it much easier to shoot with. Â I'd go for the 25mm. Â (That said, you should also take a look at the Zeiss 25mm f/2.8 - it is a lot more than the voigtlander, but I think it is a justified premium) Link to post Share on other sites More sharing options...
Ronazle Posted August 3, 2011 Share #14 Â Posted August 3, 2011 While the shootability (i.e., M8 viewfinder) argument certainly has merit, I would get the Zeiss Biogon 21mm F:/4.5. With it you know you have the best. However, it will not be useful if you "upgrade" to an M9. On the other hand, it is very useful with film cameras. regards, ron Link to post Share on other sites More sharing options...

ErikP Posted August 4, 2011 Share #17 Â Posted August 4, 2011 Hmmmm, .. 21mm or 25mm ...... Â Take the 25. If you like it -> keep i - if not -> trade. Â If you keep the 25 then I'm sure you will pick up a 21 anyhow.... Â The 35/1.4 is well worth the money. It really can't go wrong Link to post Share on other sites More sharing options...
Clive Murray-White Posted August 4, 2011 Share #18 Â Posted August 4, 2011 Hmmmm, .. 21mm or 25mm ...... Â I have the 21, find it easy to use without add-on viewfinder, both lenses f4, everybody seems to think that both lenses are very good so the chioce just gets down to how wide you want to go, or another way of putting it is, how much do want your pictures to look as if they have been taken with a wide angle lens, the 21 definitely has that look. Â Probably my greatest surprise was that you can use the little 21 very effectively at f4, so I'd guess the 25 is pretty much the same Link to post Share on other sites More sharing options...
carbon_dragon Posted August 5, 2011 Share #19 Â Posted August 5, 2011 The 25/4 Voigtlander (non rangefinder coupled) is an excellent little lens. I use it on my M8. It's wide enough angled not to need a rangefinder couple really. It was my very wide angle on the M2 and on the M8 it's taken the place of my 35/2 which in turn is now my normal lens.

lct Posted August 6, 2011 Share #20 Â Posted August 6, 2011 Another vote for the CV 21/4 P. I use it more than my Elmarit 21/2.8 asph due to its tiny size and excellent IQ from f/5.6 to f/11. It is a bit soft at f/4 but hardly more than the Elmarit at f/2.8. Cyan shift on the corners? Not on the M8 with appropriate coding in my experience. I code mine like a Summicron 28/2 but it is a matter of tastes. Link to post Share on other sites More sharing options...
