Hello,

I have a Tamron 90mm macro 1:1 but I'd like to get a higher focal lenght for macro pics of insects. The Voigtlander 180mm seems interesting, but its macro ratio is 1:4.

I was wondering if anybody has tried the Voigtlander 180mm with extension tubes. Should I expect equally good performance of the lens by adding extension tubes ??

Thanks,

David

I'll be able to answer that in about a week

Actually, while we're on the subject of extension tubes can anyone help me out? I was wondering what say 125mm worth of extension tube + 2x TC would do to :
a) the DOF ?
b) and magnification ?
...while using the 125mm lens.

Would that make the the 1x magnification something like 4x magnification? (and that's with 4 stops loss of light too?)

I have no idea what that would do to depth of focus tho to guess.

I have tried the Voigtländer 180mm with extension tubes. This combo provided good performance but it was cumbersome to use. Focusing was rather difficult because the lens is not very fast at f/4 and the extension tubes make the image appear even dimmer in the viewfinder.

my reply

figured I'd ad some updates:

I still have been using the 180mm more than the 125mm. Since many have questioned about the quality of the 180 - I figured I'd add some shots. A duck from the local lake - church (also on the same lake) and finally the moon from last night (with 1.7x AF I think). All shots were taking sometime this month, and with the vogithlander 180. I think I played with the church roof in lightroom a bit, to get it bring out the clouds a little bit. The moon shot was taken with a crappy tripod, the rest were hand held.







Enjoy - I'll be sure to post some macros and more shots as the months get warmer. I really like the 180 - starting to get the hang of the autofocus. I tend to miss from time to time on moving objects when they are coming toward me. Currently I am really relying on the green dot/beep to tell me its in focus.

That shot of the church dome and clouds behind it is exceptional.

btw, for any interested, there's a Pentax mount 125mm f/2.5 on eBay presently. Starting at I think $560; bin of $999; location is Taiwan.

My Voigtlaner 180mm arrived today, and I ran some sharpness tests indoors on a tripod. It's probably my first or second sharpest lens, maybe tied with my Viv series 1 105mm macro, and at f8, I can't see any sharpness degradation at the edges. Truly incredible.

However, the focusing ring is *extremely tight - it definitely does not have the silky smooth, easy focus of my SMC 200mm f/4.

My question - is this normal for the Voigtlander? Does it normally have a very tight/damped focusing action, or is my copy too tight?

Try warming the lens up in your hands if it is very cold. DON'T heat it or do anything silly. I've heard of people doing that with other, older lenses and it gets the movement back. worth a try.

I checked my own which arrived last week, and it is as you described, so I think your copy is OK. You won't find many manual focus lenses which match the Takumar for smoothness of the focus action.

Ditto. 180 focus is firm - but with use it seems to have relaxed... a little. I had a shoot out in Banff this past week. Weather and light were phenomenal so the shots came out nice, thought I'd share a shot from each the 58, 180 and 125.

The Lanthar 180mm


The Nokton 58mm


The Lanthar 125mm


Notes - I've grown to appreciate the 58 as being closer to the Lanthars for image quality than I had originally stated. I think the fact I can see CAs @ f1.4 in my pixel peeping was something I wasn't used to from the Lanthars, but the amounts really still aren't field relevant.

- The mountain shots were stopped down to around f8 and post edited in Lightroom and CS3. Editing aside, the details wouldn't be there to edit unless the lens was sharp enough to produce them to begin with, so its fair to say you're still seeing the sort of resolutions they can produce.

- Some may recall previously that (especially) the 125mm needs to be turned back in a touch from full retraction to focus properly at infinity. The 180 and 58 less so, but I found that a fly's breath worth of turning back in helps the sharpness with them too.

- The area presented in the 180 shot is the top right hand corner of the area shot with the 58.

Superb shots. My preferred is the third. BTW, what's on the picture?

Cheers!

Thanks Abbazz, much credit to the glass! The third image is a fairly close-up image of chunks of ice scattered on the surface of frozen Lake Minnewanka here in Alberta. It was very warm so the surface of the ice was glistening with moisture and sunlight. I filtered and underexposed most of my shots to capture as much of the highlighting as possible, hence the darker overall exposure.

Looks like a hot pixel on Pic 3.

It gives an interesting metallic look to the picture, like a Sci-Fi movie. The other two landscape shots are also gorgeous. Did you use a polarizer?

Cheers!

thanks for the tip on the 125mm, i was wondering why i was having trobles getting it to focus at infinity lol.


did you use a polarizer on the 180 for that mountain shot? The ice looks pretty fantastic.

K! Incredible, exiting shots.

After a half day playing with my 180, I've grown used to the stiff focus, and can get really precise with it now. I also think it's loosened up just a bit with use, as you mentioned.

What PP was done in the 180 shot, unsharp mask?
