Hi everybody,

I'm new in this forum,
I write to you from Trieste, Italy... Excuse me for my poor English

I have a Praktica MTL5 and these are the lenses I have:

Asahi Pentax Super Takumar 24/3.5 (awesome!!!!)
Pentacon 29/2.8
Asahi Pentax Super Takumar 35/3.5
Asahi Pentax SMC Takumar 50/1.4
Pentacon 50/1.8 (the standard Praktica lense's)
Asahi Pentax Super Multi Coated Takumar 105/2.8
Soligor 135/2.8

I'm a little bored about the Tak 50/1.4, maybe becouse it's a little
yellowed (no so much, just a little) and becouse I prefer lenses that have
more close-up (like the Pentacon 1.8/50) and more hyperfocal skills.

My girlfriend uses an old Voigtlander Vitomatic II camera with a
Color Skopar 50/2.8... this lense have a wonderful hyperfocal at f/22
from 1,2m (4 feet?) to infinity

I'm looking for a similar m42 50mm... tessar or planar style.
Do you have some suggestion?
CZJ Pancolar 50/1.8? (it closes at f/22 and it focuses at 35cm!!!)
Other?

Ciao
NI!

Welcome!

Take a Pentax M42 macro lens or Flektogon 35mm f2.4.

Hello, Ni.

The hyperfocal properties of any 50mm lens on a 35mm frame are the same as all other 50mm lenses on 35mm.

The older cameras often have marks on the lens and shutter to show the ideal settings for hyperfocal shooting, which more modern lenses lack. However, on most manual focus prime lenses you have markings on the barrel showing you what will be in focus at different apertures.

Where people go wrong most of the time, is that they focus on infinity instead of at the ideal distance for maximum depth of tield.
.
Look closely at the aperture and focus distance of your girlfriend's camera and you will find that her sharpest focus point is about 3.7 meters from the lens, not at infinity. If you set your 50mm lens to exactly the same aperture and focus distance, you will get exactly the same depth of field as she does. You do not need another 50mm lens to achieve that.

There is a focal-length calculator here: http://www.dofmaster.com/dofjs.html

I hope that helps.

Paul

PS: The cheapest M42 50mm Tessar-type lens you can find is the Industar 50-2. I haven't tried one, but lots of people seem to like them.

Welcome aboard!

You've hit on one of the things that makes rangefinder cameras feel diffrent than SLRs - you're more 'outside' the camera, and therefore pay more attention to the lens markings etc. Plus, as Paul says, often the older range finders have the better markings.

Paul's advice is sound: you can get the same performance from your current lens as your girlfriend (congratulations, by the way: she has excellent taste in cameras, and boyfriends I'm sure).

But perhaps your two 50mm lenses only close down to f/16? The Pentacon if I remember focuses very close... but I don't recall the minimum f/stop. Without buying another 50 with the f/22 stop, if you can live with using the 35 (yours is excellent) you can get a wider hyperfocal zone even at f/16.

As PaulC said above, the hyperfocal distance depends on the aperture and focal length, so any 50mm at f/22 has the same hyperfocal distance. Of course, hyperfocal distance itself depends on the definition of what is “in focus”, so different manufacturers may use slightly different definitions for making their depth of field scale (e.g. Zeiss has notably used a definition more strict than some other manufacturers).

Note, too, that if you focus at the hyperfocal distance, things “at infinity” will be just barely in focus by the definition of “in focus”. This means that you will usually have better results at long distances (“infinity”) by using plain infinity focus. So one should generally use the hyperfocal distance only when it is important to have nearby objects in focus.


As for lenses, well, the Pancolar does indeed focus closer than many other 50mm's. Most of them do stop down to f/22, and stopping down more than that is not very sensible on small formats due to increasing loss of resolution due to diffraction.

For close focus you could also consider M42 extension tubes (very cheap), or a reversing ring (also very cheap and gets 1:1 magnification easily, but at a very short working distance).

In fact, f16 is probably a better aperture for sharp images than f22 where diffraction may start to soften the image just slightly.

Set the lens to focus at 5.3m and, at f16, you will get DoF from 2.6 meters to infinity, which is not bad at all.

Fwiw, I have the Meyer Oreston 50/1.8 (same lens as the Pentacon as I understand it), mine goes to F16, but its short MFD of .33m (vs .45 of many 50's) is quite fun. I love the bokeh as well (very strong NiSen, disliked by many, but loved by me).

Welcome

I would suggest a Zeiss Tessar 2.8/50mm. Great image quality, focuses mini at 0.35 and has the f22 stop. about 20$/£ € whatever Very Happy

The hyperfocal focus tend to make the viewfinder like seeing almost all "out of focus" and it can be confuse.

To use the "hyperfocal" seems to me that the better is a wide lens (20 to 35 mm). And if you can catch a "external" finder, better yet.

With RF cams the question is different. The finder is OK when you use the "hyperfocal". Perhaps the pics can be a bit sharpest at F/16 with the very nice skopar lens.

If you want, put the SMC 1,4/50 to the sun light (or UV) in the mode that this site describes. It can be better lens than the pentacon.

Good luck.

I'm so pleased with my vivitar 55mm f2.8 macro, I'm not saying it's the sharpest although mine gives excellent results, and you wont need a lens hood and I'm guessing they make a m42 version, and they are still going fairly cheap.

Viv macro superia 200asa first ever attempt at macro shooting (cos I never had a lens before)

That's a very nice shot; good composition, good focus and nice colour contrast. Well done!

MC Volna-9 50mm f/2.8 is also nice and focuses down to something like 24 cm.


PostPosted: Wed Sep 09, 2009 10:18 pm    Post subject: Reply with quote

another vote for the Volna. Or Industar 61L, also 50mm 2.8, close focus to 0.3m and smaller than the Volna.

Well thank you but the camera did all the work, I just put the film in and focussed.................. Smile

Yes, as soon as I saw it, I thought to myself "That guy must have a really good camera". Laughing

I highly recommend MC Industar 61L/Z ('Z' means it's M42 for SLR cameras; L/D is for rangefinders, you don't want that). It can focus really close, down to 0.3m, and is very, very sharp straight from wide open. I'm using a 21MP full-frame body, and it is still extremely sharp on it! It employs an improved Tessar formula with lLanthanum glass (that's what 'L' stands for in its name). Can be had for around $50-60 in like-new or even new-old-stock condition.

Volna-9 (50/2.8 ) is another contender with quite a unique optical construction and very pleasant rendering. It has that 'glow' wide open (undercorrected spherical aberration), but gets super-sharp and contrasty from f/4. It has, to my eyes, a more pleasing rendering than Industar. Unfortunately, Volna-9 had been discontinued early, and is now quite rare, often fetching quite elevated prices on eBay. If you stumble upon one in good condition, expect to pay $100-150.

Funny story:- I won the lens for Canon FD, got it cheap and it was for a Minolta, but it was in a leather lens box with Canon on the o/s so the seller assumed..........
Anyway rather than send the lens back (as it was mint and cheap) I bought a Minolta X-700 to use it.........I usually don't care about camera bodies (they are just a tool) but there is something about this one that I like.

+1 for the Industar-61. Very good and nearly a macro lens.
