adan Posted July 14, 2006 Share #21 Posted July 14, 2006 Advertisement (gone after registration) RE: 50 ASPH vs. 75 ASPH I've been reorganizing my lenses in preparation for the Digital-M. Picked up a 50 'lux ASPH thinking I could use the f/1.4 aperture more than the extra focal length. And the digital crop factor would make it a nice tight 'portrait' tele. And it's 3/4 the weight of the 75 f/2. Ooops! The 50 1.4 ASPH is clearly less sharp close-up than the 75mm ASMA (APO-Summicron-M-ASPH) at wide apertures. And I tend to use these focal lengths in the 1 meter 'portrait' range far more than infinity, where the 50 is very good. Swapped the 50 for a 75 ASMA within 5 days. Happier now (even though I must use the 75 with a film M4-2 with no 75 framelines for another 2 months). If it's confusing that I got a 'new' 75 ASMA when it appeared from my previous post that I already had one - well actually, this is my THIRD. It's taken me a while to get my head around the 75mm focal length. But on the digital camera it will be a "100mm" that focuses to .7 meters - that's tighter than most SLR 85/100s. Third time's the charm. Quote Link to post Share on other sites More sharing options...
Advertisement Posted July 14, 2006 Posted July 14, 2006 Hi adan, Take a look here Summicron-m 75 f2. I'm sure you'll find what you were looking for!
Guest hagen Posted July 14, 2006 Share #22 Posted July 14, 2006 BTW, here an example with the 75 Summicron @ 2,0. One of the best lenses I ever used in my life! Welcome, dear visitor!

wbesz Posted July 14, 2006 Share #25 Posted July 14, 2006 Andy, you say that you have done a real comparison (close up) between the 2 asph lenses, and can really see the difference? Quote Link to post Share on other sites More sharing options...
Guest hagen Posted July 14, 2006 Share #26 Posted July 14, 2006 William, the following shot shows Rolf Adam a fotographer from Cologne. The shot was made with 50 ASPH @ 1,4 on ACROS 100. I can't see any difference to my Summicron 75 lens. Both are first class lenses without any restrictions. The only restriction is the film. Welcome, dear visitor!

Guest hagen Posted July 14, 2006 Share #28 Posted July 14, 2006 William, I tried both lenses in Solms and decided for the 75 ASPH cause I also love my 1,4/50 non ASPH as you can see the following picture :-) Welcome, dear visitor!

wbesz Posted July 14, 2006 Share #29 Posted July 14, 2006 Yes, not worth updating your current non-asp 50 when you can add another useful focal length lens. (I see you too appreciate creative use of short-depth-of-field ;-) Quote Link to post Share on other sites More sharing options...

adan Posted July 15, 2006 Share #31 Posted July 15, 2006 Wel, Mark and Will B., I WAS pixel-peeping at 4000dpi scans from Pan F - and what's noticeable there may not be all that noticeable in a print ... ...especially when the lighting and everything else is as - distractingly good - as it is in Wolfgang's portrait. Plus I was at the extreme close limit for the 50 - 0.7 meter - and f/1.4, compared to 1 meter and f/2 for the 75 (for similar framing). The flip side is that in the tests I did with the 50 ASPH vs. the last two generations of 50 'cron at 2.5 meters - the 50 ASPH was slighty better at both f/1.4 or f/2 than either of the 'crons @ f/2. (!) But the 'crons seemed to pull slightly ahead again down in the range under 1 meter. Something LFI magazine also reported in its reviews of the current 50s and 75s over the past two issues. I'm not sure these results are that surprising - the 75 has a very similar optical design to the 50 ASPH (including the floating element), plus the benefit of a narrower angle of view and a more conservative aperture. And it still only pulls ahead of the 'Lux in the last 60 cm or so. Quote Link to post Share on other sites More sharing options...
adan Posted July 15, 2006 Share #32 Posted July 15, 2006 FULL DISCLOSURE: Perhaps I should also confess to a little bias in favor of the 75 ASMA, seeing as how I "invented" it.... http://www.photo.net/bboard/q-and-a-fetch-msg?msg_id=004jpi ...sort of (note date of posting - 2 years before lens was delivered by Leica).

MP3 Posted July 15, 2006 Share #33 Posted July 15, 2006 Hi there Also been thnking on the same topic as which of these 2 lens shall fit better to the coming M8, esp when I'm moving a bit from the 28/50 to more closeups on kids. Here are shots I took recently with my 50 Lux Asph on my lady model, then cropped as an "M8 simulation". The shot was taken at 1.2m then cropped from 50mm to "approx.100mm focal length". I understand it's pointless to be over critical on uploaded resolutions... but just what do you think? Cheers Matthew Welcome, dear visitor!

Rolo Posted July 15, 2006 Share #34 Posted July 15, 2006 Wolfgang, Very nice images. Have you got a portrait that is at 0.75 mteres to post ? I'm wondering how close to an eye&mouth pic you can get or a babies headshot. Regards :confused: Quote Link to post Share on other sites More sharing options...

I'm wondering how close to an eye&mouth pic you can get or a babies headshot. Regards :confused: No, I don't have one available. As far as I remember the distance for the portrait of my daughter wasn't much more than 1 meter. If it helps I'll shoot one :-) Quote Link to post Share on other sites More sharing options...
Rolo Posted July 15, 2006 Share #36 Posted July 15, 2006 Thank you Wolfgang. If you did shoot one I would be most interested to view it. Alternatively, if anyone can identify the size of the field at the closest focus I would appreciciate the information. A great advantage of the digital cameras I've use (not many) is their close up capability. For my film M, I need to fill the frame more than I can with my 50mm Summilux. Today I shot a wedding and the Minister was quite adament that there could be no movement during the service. Her reason for this is that people need to focus on it without the distraction of a photographer moving around. It seems strange that this 'important' moment cannot be recorded. Hence it's essential that I get a longer lens for my 35/50 combo and I believe the 75mm would be more useful than a 90mm. Quote Link to post Share on other sites More sharing options...

Of course, you obviously have a very compliant model. You should have quite a good collection of this little imp when you are done. Rolo, Look at my example which Allan posted at the beginning of this thread if you want to view a shallow DOF shot at less than 1 m. Quote Link to post Share on other sites More sharing options...
Rolo Posted July 16, 2006 Share #40 Posted July 16, 2006 Wolfgang, Brilliant and very co-operative of you. Just what I am looking for. Very nice model you have on hand. I was less concerned about the maximum aperture, but it's really useful to see the effect that has as well. Many thanks. Cheers William, I'd spotted the Bentley pics earlier.
