After searching the forum for occurrences of the word "Novoflex", i realized that there are NO reviews of Noflexar lenses, and that there are VERY few references to vintage Novoflex products.
Of course i'm not taking into account the line of high quality adapters rings, often used by fellows members who want to use lenses of different brands with recent digital cameras, like for example the various four thirds bodies, or the Sony NEX.
Having recently purchased a few Novoflex products, both macro and follow-focus lenses, i decided to write two different posts, discussing the matter and asking for help/advice from well informed fellow pentaxians (especially german ones, as all the Novoflex products are/were made in Germany, and most of the literature can be found in german language).
Here is the first post, about macro stuff.
Another one about follow-focus outfits will follow soon.
First let's put everything in perspective, and let's tell you why i got interested in Novoflex macro stuff.
I own an old Panagor automatic bellows (bought LONG ago), still in its box and like new, for which i purchased a solid focusing rail, and a slide duplicator attachment. It was the golden age of Pentax: sales were probably a little down, compared with the Spotmatic days, but the MX (and the line of Pentax-M lenses) were the perfect answer to Olympus OM equipments, and the introduction of the LX was stealing all the headlines.
I found a Pentax-M 100mm f/4 Bellows, and as the name implies
... i needed a bellows outfit. Tubes were not flexible enough, or at least that's what i thought...
The Panagor bellows was well made, just a notch down, compared with the original Pentax. When i bought it, it was cheaper and more innovative. Instead of using a double cable release to close the diaphragm at working aperture while triggering the shutter, the Panagor had a mechanism to trasmit the movement of the two diaphragm levers, just in conventional P-K auto extension tubes.
At that time the solution was smart, now it can even become a nuisance.
Digital cameras have a crippled P-K mount, hence the need to push the green button to stop-down for exposure measurement. The diaphragm is still automatic, but you loose wide-open exposure reading.
I must admit that it is not a major inconvenience, if a tripod and a double rail are used. Though i can't get accustomed to it in general photography, or (even worse!) with a "macro hunting" setup with bellows/tubes and two flashes.
After giving it a thought, i realized that a M42 lens/bellows setup was preferable. Of course a P-K set without auto diaphragm would work the same).
Such setup would allows to use Aperture Priority, along with the usual Manual mode, and i guess the handling of the camera would be much more ergonomical, especially with preset lenses (i can't stand using the green button, i prefer working in Av and using the preset switch jut before shooting. For tripod use, a bellows with auto M42 mechanism, and two cable releases, would work even better.
That would allow to use M42 macro lenses, which are not so expensive, and easy to find.
Unfortunately there are not so many preset M42 macro lenses, with superior quality and MC coating. Okey, there are many of them, but NOT that many, and the best ones are not that cheap. The best bargains, quality vs price, are single coated.
That's why i started looking with great interest at the Novoflex macro lens line.
Before the recent attack of compulsive buying syndrome, i owned just two Novoflex items.
One is a nice macro flash attachment, orientable, which screws in front of the lens.
The other is a bellows lens head of quite long focal, the LEINO-200 200mm f/4.5, with LTM attachment. Now that i think about it, it's the black extension tube which has a Leica thread mount. Not sure about the lens head itself.
I must admit that i never tested the 200mm macro lens, despite having already a LTM-to-M42 ring, and a M42-to-PK original Pentax adapter.
After i purchased it (NOS, at a clearance sale), i moved back to analog for some time, with large format cameras, so i had no chance to test its performance.
After my recent comeback to digital photography, i got curious about other (shorter) Novoflex macros. On APS-C, a 200mm bellows is, well... not the most useful lens
I started searching, at first just for curioisity, then i couldn't resist: along the follow-focus stuff, which is kept for the next post, i bought a 135mm macro lens. I thought itwas a good choice, cause i knew that it came from a reputable lens maker, well know for its good repro glasses: Staeble. I also thought that the build was reasonably recent (Novoflex 60er Jahre), which should vouch for a decent coating.
The complete name/description of the lens is: Novoflex-Noflexar 1:4,5/135mm R in Novoflex Automatik mount (which is a mount with an A/M slider and a threaded socket for a mechanical cable release, which i think should be used with a double release, to close the iris at working aperture and trigger the shutter at the same time). As already said, it's the "60er Jahre" version.
The 135mm should be a M42 lens, that's what the vendor wrote in the text of the auction. Maybe it was made with different attachments, i don't remember... what i remember is that i have seen a similar lens in "Automatik" mount, it was a Schneider Xenar 135mm.
As we say in Italy, appetite comes eating, so i tried to buy other two Novoflex macro lenses: the Novoflex/Staeble Katagon 60mm and the small Novoflex 35mm Macro. I lost both auctions
There is another (more modern) macro lens, available with different mounts, it's the 105mm. I didn't try to win a M42 or P-K version cause i didn't find a decently priced example.
The 60mm katagon is an old lens, while the 105mm and the 35mm are not so old, they should still be good value. maybe sooner or later i'll buy one.
I find the 35mm wide-angle macro especially interesting, more so with APS-C digital cameras. It was made with mounts for all the main camera makes, IIRC, and at the time was one of the best, if not THE best, 35mm macro lens. It has a 1:1 focusing helicoid, which can be used separately, as far as i remember. At 1:1 the subject is close to the front glass, but the element is not recessed, as in some 50mm macro lenses, so the front lens should not be to close to the subject, even at 1:1.
When i'll be back home, i will try to find the time to test both 135mm and 200mm macro heads.
In the meantime, if somebody has some experience with the other three focals, i'd be very interested in your opinions.
There are no infos about them on this forum, i think many macro enthusiasts would be very interested.
At the moment, if i find a true bargain i'm considering to purchase a Novoflex M42 bellows. Often you can find a complete set on Ebay, with accessories, cheaply priced.
With one of the simple Novoflex M42 bellows, all i need would be a M42 to P-K adapter ring, which i already own.
The solution i'd prefer would be with the ring glued to the bellows (maybe the red semi permanent glue used in engine repairs would be perfect), with the small spring removed, and with the indent for the P-K retaining pin milled on the back surface of the bellows.
I never hada simple Novoflex bellows in my hands, from the pictures i've seen i couldn't realize if the mating surfeace at the back of the bellows is large enough to allow cutting such indent.
To complicate things even further, there are different kind of bellows, monorail and with two rails, with integrated or accessory focusing rail, and dedicated (for one brand) or multi-brand (using the same adapter rings used by PIGRIFF-C and PIGRIFF-D "machine guns", or by the BAL-U reversed bellows which allows close range shots with the older follow-focus PIGRIFF-B).
If somebody owns an M42 Novoflex bellows, i'd like to know if a semi-permanent M42 to P-K modification is at all possible. That way it would be "seen" by the camera body as a plain-vanilla M42 lens, but with the added advantage of having a bayonet mount (which allows quick mounting).
Of course a Pentax K bayonet adapter (without diaphragm simulator) would be a more elegant solution, but the Novoflex bellows with interchangeable adapters are usually more expensive, and not so easy to find.
For example, the super simple PENTA adapter ring for interchangeable Novoflex bellows (also usable on the BAL-U, the PIGRIFF-C and PIGRIFF-D) is practically impossible to find on Ebay, and is sold by Novoflex for 70 eruos plus shipment! For that money you can easily find a complete bellows set, with double rail, dia duplicator, adapter ring, and maybe even a macro lens and the double cable release!
Such bargains are not common, but i have seen that complete sets and bare bellows don't sell for very different prices...
My long blurb already contains a few questions, but i would be happy enough with ANY information about Novoflex macro stuff.
Are there other macro lenses?
Are some of the recent ones any good?
Are all the multi-brand bellows (BALCAST ?) fitted with the socket for the second cable release (for auto diaphragm)?
Are there chinese knock-offs of the original Novoflex adapters, like the COA or the PENTA?
For macro, would you prefer auto diaphragm + M/green button, or Av with preset slide or double shutter cable?
cheers
