What bayonet filter size is Sonnar 150 f 2.8? 60 or 70?

 

thanks

I'm talking about Decaprio's portrait i particular.

Anybody can guess what kind of equipment did dan winters use for his

portraits? Light seems to be concentrated on a small area yet

soft-edged.

 

Fresnel spots?

Have anybody tried using this lens mounted on on a camera for 3-d

macro work?

 

thanks

what is the difference between silver nad white lining of umbrella

and beauty dishes? Silver lined reflectors tend to be more

expensive, but how does it affect the look?

 

thanks

Thanks Michael,

 

It's really hard to imagine the effect until I see it.

 

Now, since you mentioned chromoatic aberrations, and practically speacking, I was really wondering how does such effect (of SF lens- with and without disks) go with color. I understand that most of the responses here are based on B&W.

Ahmad

Sounds strange, I thought the disks add to the softness rather than sharpen the image!

Does anybody have any experience with Fuji SF lenses? I have a

Pentax 67 soft focus lens and i love it; that's why I'm considering

250sf for 4x5.

How does this lens perform without the disks? And is it possible to

get soft focus effect with the lens stopped down (using the disks)?

 

I wonder if there are any galleries online exhibiting LF soft focus

photography.

But the rubber ring was introduced later. I wonder if it was accompanied by different coating technology?

 

Also I noted that KEH describe some lenses as SMC and others as SMC "late". (the 90mm for example). What is the difference?

I recently read that Symmar-S is of symmetrical design. I wonder if

this means that it's optimize for close up work. Any experience with

such application?

 

thanks

I was wondering if the newer rubber ring versions of pentax 67

lenses have different coating from the older metal ring ones. I'm

talking specifically about the 90mm and the 135mm macro lenses.

 

thanks

I heard that dektol used as a film developer can yield some nice sharp grainy results- which is actually my main objective here. I want to know in what concentration should i use it? I know that Kodak polymax developer is dektol, but what ditlution is suitable for film? And would it change the speed?

well I tried it & the results came out bad but not realy

disappointing.I first developed it in a film developer

(ilford id-11, 1:3),reexposed, bleached for 12min, & 2nd developed it

in the same developer. The results came out a very dense positive. I

noticed that some shouts are less dense,better, than the others; these

were the underexposed shots.So next time I'm gonna overrate the film

upto 6 stops & try again.

I'm also considering droping the idea of reversal processin for just

solarizing an extremely under exposed negative to get a positive.

I'll kee you informed.

What are the advantages/disadvantages of using longer developing times at hight dilutions, beyond better control over the whole process?

Do I get higher sharpness? more grain?

I want some advice regarding B&W slide processing. I'm gonna be developing tmax 100 into slides; I was thinking about using a paper developer as a second developer to increase the contrast. But how should I rate the film speed, & how long sould I bleach..,any other advice/recommendation?
