telenous said:Excellent thread, very informative and a great read. ...
Now, wouldn't it be nice if we had such a group for M-mount lenses? ... That would be a kind of treasury of photo samples for the specific mount. ... Preliminary I 'd like to see how members here feel about this idea. ... If this group is not a diagreeable prospect perhaps I can contact t a few members here who are steeped into M-mount lens history to ask for their administrative wisdom and go ahead with it. And although I am far from being a lens expert myself I am definitely willing to put the hours and help build this group.
What do you say?
Best,
Crasis said:Half the shots shown are out of focus. Rather strange to use them as shots showing the power of one lens over the other.
jaapv said:Whatever gave you the idea that this thread was a lens competition or even a lens test? The posters used their shots (and a considerable number of those shots were rather good photographs imho) to illustrate their point, not to prove it.
Having said that, you are right that one cannot compare anything either way by looking at jpegs on the internet, except for the most crass differences.
Crasis said:Throwing semantics at me? Have you actually read the thread?
I have no experience with the cron iV but am a huge fan of the 35 lux pre-asph myself .......... another lens considerd unusable wide open if you believe the forums. Myths as you say ..... and i agree .... myths that get a lot of parotting by people who never actually used the lens! Before you know it is a fact😀adayoncedawned said:I realize that I am a bit of a latecomer to the thread and that I'm digging up some of the older posts, but this is a myth that I am really interested in:
Who exactly was it that started the whole Summicron Pre-ASPH is unusable at f/2.0-2.8 thing? I mean I am presuming that it must have been someone significant.......
venchka said:Very good examples. I would have expected more depth of field at f:4.0. I'm glad to see the DOF is still suitably shallow at f:4.0.
J. Borger said:My last words before i get out of this thread are dedicated to you.
You think this thread is about sharpness?? If so ..... all i can say is your stupidity really hurts!
Yes very sharp ASPH lenses indeed..... but although i did not state it explicit in this contribution ..... i happen to prefer the pre-asph lenses in most of the circumstances ... so start reading again ....... and read carefull between the lines! You might read something to your liking ......
That's my entire point. People are being swayed one way or the other.. or agreeing whole heartedly for shots posted in a format that make one thing indiscernable from another. This is one of my issues.jaapv said:I think I wrote part of it....
How can you tell a 3 MP sensor on a 600x800 300 Kb shot btw?
x-ray said:Going back and looking at the examples posted has brought me to a conclusion of no conclusion if that make any sense. The images that I look at are not controlled and the various shots are under drastically different conditions. There's no controll standard to judge by and there are just too many variables fom shot to shot, film, scan, exposure, lighting and etc. Looking at shots like the wine glass that's lit from above on a white cloth doesn't tell me anything about the lens but tells me the glass was backlit to some degree and it was thick glass. If lit from the front it would have a totally different look as it would if lit from each side or one side. In viewing each example I see the differences more due to lighting, processing and etc. then the lens itself. OK tell me I don't know what I'm talking about but my experience tells me different. The only true test would be to shoot under controlled conditions with the same film, processing, model, lighting with the lens as the only variable. Examine the negs side by side and scan them as a single scan not individually. Scanner software and some scanners can alter each result. If there is a real visual difference it will show up in a B&W neg or slide.
Sometime this winter I'm going to make a test and hope some of you will help. I will take a number of my negs made on different cameras, lenses, makes of lenses and formats and make 11x14 museum quality arichival toned FB prints and send them to a person on the forum that would like to tell me what they were shot with. That person will have to send them to the next and so on. I will only number the back and post jpg's on the forum. After a few weeks of sharing I will post the results. Atleast tell me if it's 35mm or larger, leica or other glass. I hear some forum members can spot a leica image from across a room. Subjects will be different and the film / developer might be different. The images might be all leica or none may be. I want to see if I'm blind or if the "glow", "clinical look", Leica look and etc. are real or not. Anyone up for a real test?
adayoncedawned said:Are you certain? From the container of lens cleaner on the table to the fence behind the subject is a considerable distance.
This mistake actually demonstrates my point quite well as you can see there is not much difference in contrast and sharpness from f/2 to f/4....

Edit: I have decided to attach a file. This is a scan of a print, shot with Delta 400 pushed to 1600, 35/2 pre-asph at f/2.0.
I'd like to note how hideous Delta 3200 at 1600 looks in comparison. I'd also like to note that any thread in which one pontificates on the virtues of the aspherical lenses necessarily brings to bare the sharpness factor. Why else would you want aspherical lenses if it were not for sharpness, flatness of field, etc.
Well, I've heard one good argument. The pre-asph lenses are too small for larger hands to handle. That's one of the only good arguments I've heard that isn't about sharpness.
