Adams Posted December 2, 2008 Share #1 Posted December 2, 2008 Advertisement (gone after registration) Hi, Which one is better when contrast and minimal focusing distance are consider? is 0,7m to long for 28mm? Regards Adam Link to post Share on other sites More sharing options...
Advertisement Posted December 2, 2008 Posted December 2, 2008 Hi Adams, Take a look here VC 28 2.0 vs Zeiss 28 2.8. I'm sure you'll find what you were looking for!
JBA Posted December 2, 2008 Share #2 Posted December 2, 2008 0.7 m is the minimum focusing distance of my 90 M and R lenses, for what it's worth. Sounds quite far for a 28. Link to post Share on other sites More sharing options...
rocheung Posted December 2, 2008 Share #3 Posted December 2, 2008 helllo, I don't have the profile of CZ, but I just got some VC 28. Only the pciture with a creek was taken in F8. All of the others were F/2. So that you may see the bokeh and the contrast. Vigneting is noticeable in F/2 but I don't whether it came from my filter or not. I expect the tone of CZ will be warmer. Basically , I am pleased to its performance, but I think I need to take F2 pics with the filter being removed. Hope there will be improvement on vignetting. The pics are quite contrasty even at F2, no PS no aftertreatment. Please enjoy Regards Cheung Link to post Share on other sites More sharing options...
Guest zwicko Posted December 2, 2008 Share #4 Posted December 2, 2008 Picture #4 is really nice! Did you use an ND filter for it? Cheers, Zwicko Link to post Share on other sites More sharing options...

tgray Posted December 2, 2008 Share #6 Posted December 2, 2008 RE: 0.7m min distance. Depending on what you shoot, I haven't found that the 0.7m minimum focal distance is that confining. For people shots its not a problem at all for me with 28mm. If it was shorter (like it is on my SLR), I am tempted to get closer, which causes some funny perspective issues which are unflattering to my eye. For some 'object' photos, it can be a bit far, but I survive I actually found it a lot more limiting when I shoot with a 35mm lens. I kept on trying to make it act like a 50mm and bumping into the 0.7m limit. With the 28mm on the camera, I don't try for those shots, and when I really want to take one, I just swap out for the 50mm. Link to post Share on other sites More sharing options...
rocheung Posted December 3, 2008 Share #7 Posted December 3, 2008 Advertisement (gone after registration) Hi Gentlemen, IMHO, I think that RF may not be a good equipment to take close-up picture, as close as an SLR. Other than the focusing difficulties, the other problem is the parallax difference. What you see in the VF may different to what you take. Frankly speaking, I am new to RF and I love taking portraits. But I found the parallax become more noticeable and need some adjustment of my camera position. Up to this moment, I still cannot familiar to this. Link to post Share on other sites More sharing options...
guywalder Posted December 3, 2008 Share #8 Posted December 3, 2008 Hi, Which one is better when contrast and minimal focusing distance are consider? is 0,7m to long for 28mm? Regards Adam excuse the silly question, but how are you going to focus and compose at less than 0.7m?? I just got the VC28/2 and it looks like a total bargain, I also have the 28 summicron and so far I havnt seen any significant difference (caveat: without any back to back testing, and only used on M8). The focussing action on the VC is pretty stiff though, smooth but stiff. The vignetting in Cheung's pictures looks very inconsistent, strange. All these, except the first picture, VC28/2 on an M8: Guy Walder, Cambodia Link to post Share on other sites More sharing options...

All these, except the first picture, VC28/2 on an M8: Guy Walder, Cambodia I have a Heliopan filter on it. May it be affected? From my experience, Leica's image is sharp but more rounded and smooth, silky feeling. Other brands such as CV and CZ may have a bit harsh. do you notice such difference?

rocheung Posted December 3, 2008 Share #10 Posted December 3, 2008 Hi Guywalder Have a look on the link below. The pics is taken by another guy without using filter. The first three floral pics (especially the 2nd one) also got vignetting. Any comment?

guywalder Posted December 3, 2008 Share #11 Posted December 3, 2008 Hi Cheung, some of those also look strange, maybe due to using a polarising filter? I havnt seen anything strange with mine, but like I say I have only used it on my M8 so I am not seeing the FF corners. My 28 summicron vignettes rather more than I like (at f2) on a film camera, but at least it is consistent carner to corner! Link to post Share on other sites More sharing options...
spylaw4 Posted December 3, 2008 Share #12 Posted December 3, 2008 FWIW the Zeiss 28/2.8 is an excellent lens with good contrast. I've used it on my M8 quite a lot. The shortest close focus mark on the lens is 0.5m. Link to post Share on other sites More sharing options...

My 28 summicron vignettes rather more than I like (at f2) on a film camera, but at least it is consistent carner to corner! The inconsistent vignetting is actually due to the use of a polarizing filter. The effect is stronger as the angle against the light changes. Neither of the CV 28's vignette as much as my Summicron 28 did. In the end I sold my Summicron because the vignetting was too intense for use with slower slide films like Velvia. If you are shooting lower contrast films it would not be a problem. Best wishes Dan Link to post Share on other sites More sharing options...
tgray Posted December 3, 2008 Share #14 Posted December 3, 2008 The vignetting on the 28mm Summicron is interesting. In the tech sheet from Leica, it doesn't show any more vignetting than most other lenses, but it is definitely there and definitely noticeable. I wonder why the discrepancy? Not that it bothers me.

Hmmmmm, I have bought a Vario ND filter (put two PL together) but I remember I haven't applied . Have I made a mistake??? Oh my memory is bad. But I am sure the one with a white road sign with a tree behind i haven't used that vario ND. Because the lightmeter show me that the shutter speed should over 1/4000 a little , but I am too lazy to take out my PL, so I haven't applied. Is that pic inconsistent?
