Hi All, I had some other questions about this TC :

1. I assume that macro teleconverter means an ordinary teleconverter for macro lens/ macro photography. Or is it a dedicated teleconverter designed for macro photo?

2. If I want to convert front & rear mount of this TC to EOS (so I don't have to buy multi mount TC Smile ), which mount is the easiest one to convert?
Or should I buy another TC such as Kenko instead?

Thanks.


1. The Vivitar is a teleconverter that can be used for both infinity and close-up photography. The helical allows you to focus closer than you would with the lens used on its own. I don't know whether it is optimised optically for close-up work. A similar looking Panagor macroconverter only allows close-up work, no infinity.

2. Buying an EF TC is much easier. Converting the front mount of a Vivitar 2x TC Macro will be a serious challenge.


Thanks a lot for the explanation and advices.

Sorry, I press the Submit button to fast Smile

The story is this, at first I bought Vivitar 90/2.5 macro lens but stupid me I didn't check the mount and it's Minolta mount.
But I have no heart to convert it because it's a rare lens Smile
Then I read this thread and got an idea to buy a Vivitar 2x TC with Minolta mount and modify the rear mount of the TC to EOS.

On the other hand I also need a 2x TC for my MF Nikkor tele lens.
The Canon EF TC can only be used with certain EF lenses, due it's proturing rear elemen. So, I thought that maybe this Vivitar TC could be modified to EOS mount TC Smile

Is your Vivitar 90/2.5 the Komine made (serial number starting with 2Cool or the Tokina made (serial number starting with 37) version? The Tokina made version has a specially designed macroconverter for it to get to 1:1.

If you want to the M/SR mount lens on your Canon, you could use a Rollei/EF adapter with it. With my Tokina 90/2.5 in SR mount I can focus to about 5 meters this way. Its disadvantage is the friction fix between lens and adapter - you need to be fairly careful when handling this lens/camera combination. If you use this adapter only on this single lens, you can use some teflon tape to make the connection more secure. Alternatively there is a glassless Minolta SR - EF adapter available on eBay, but it adds about 10mm extension, so it is only useful for close-up work with a 90mm lens.

It should be possible to convert the rear of a Minolta mount Vivitar 2x macroTC to EF, but I haven't tried it yet. The combination of Tokina 90/2.5, Vivitar 2x TC macro and Rollei/ef adapter gets me a maximum focus distance of about 20 meters, but the connection between Rollei adapter and TC is less secure than between Rollei adapter and Tokina lens.

It's Tokina made version. The most sought after version Smile
Is there any specific name for this special macroconverter? as a guideline if I search them on eBay.

Thanks for the tips of Rollei-EF mount.
By the way I just ordered the optic-less Minolta-EF adapter from eBay that you mentioned. Well, I know it will function as a short extension tube dan will have short focus distance, but I can't wait to try the lens any longer Smile

I will give a try to the Vivitar+TC+Rollei-EF adapter combo as soon as I get the TC later.

Anyway, I just realize a stupid flaw in my plan. If I modify the front part of the Vivitar TC to EOS then how could I mount it to the Vivitar lens with Minolta mount ... Very Happy Very Happy

So I need 2 TCs, one is specific for the Vivitar 90/2.5 lens (mount it to camera using Rollei-EOS or modify the rear part to EOS),
and one for "general purpose" EOS mount lens or any lens which has adapter to EOS (modified both front and rear part).

For the second TC, does anybody have experience comparing the Vivitar TC vs Kenko 2x DGX TC? If the difference is not noticable or the Kenko is better, I think I should get the Kenko to eliminate the conversion problem.

On the Vivitar version it says: "Vivitar Series 1 90mm f2.5 MACRO ADAPTER". This version has a rotating tripod mount, the Tokina branded one hasn't. The Tokina version reads: Tokina AT-X MACRO EXTENDER. Both versions appear very similar (I don't have them in the same mount though) apart from the coating, which is more cyan on the Vivitar and orange/purple on the Tokina.

How important is it to you to be able to focus past 6 meters with this lens? If it is, my suggestion is to sell the SR mount lens to someone shooting a NEX. If it isn't, get a Rollei adapter and fix it non-permanently with teflon tape.

Using an adapted or modified TC results in a 180mm f/5.0, which is great for chasing butterflies but not fast enough for shallow DoF portraits.

If you use a non-chipped lens on an EF teleconverter, you may get problems, with the electronics in the converter telling the camera there is a lens that doesn't communicate with it. My 1.4x Kenko 300 Pro DG doesn't work, neither do my EF extension tubes. You can get around it by taping the electronic contacts of the converter. Other converters appear to be of the non-reporting kind and won't clash with non-chipped lenses.

Someone mentioned a Panagor Macro focussing converter.

I just found one I didn't know I had, came as part of a job lot of lenses.

It is labelled 'Panagor Auto Macro Converter' and inlike the Vivitar turning the focus moves the internal optical group back and forth.

It is in Konica bayonet mount so I can't use it on my EOS I think.

I have a Hexanon 3.5/135 and it fits the converter, but I suspect it needs to be used with a 50mm lens.

So I'm wondering, is it worth me getting a 50mm Hexanon to use with this converter and then modifying it to Canon EF to use on my EOS?

Or would it be better to sell it on to a Konica user?

I wasn't too impressed with my Panagor Auto Macro Converter. It takes a lot of light and only with a 50mm did I have reasonable results. That was a long time ago though, search this forum for more positive comments.


PostPosted: Mon Aug 01, 2011 6:44 pm    Post subject: Reply with quote

Looking on ebay there are several listed in the 30-40ukp range, this one is almost mint so I think it would be better to pass it onto a Hexanon user than chop it up to modify it.

Anyone want an excellent condition Panagor Auto Macro Converter in Konica mount? Going cheap to the right home!

Thanks for the TC tips.

It came up in my mind too at first place, but I want to try this lens so bad Smile
But, yeah, I think it's better to sell this lens and wait for the M42/Nikon mount.

By the way, just for curiosity, what is the optical & functional difference between Vivitar 2X Macro Focusing Teleconverter MC and Vivitar Series 1 90mm f/2.5 Macro Adapter?

These are completely different animals. The Vivitar 2X Macro Focusing Teleconverter MC is a 7 element (if I remember correctly) 2x teleconverter with a built-in focussing helicoid for additional macro capability, designed to be used on a wide range of lenses for infinity focus and close-up. The Vivitar Series 1 90mm f/2.5 Macro Adapter is a 3 element (if the diagram on the Tokina AT-X box is to be trusted) macro adapter, designed for use with the Vivitar Series 1 90mm specifically, and shifting the range of focus of this lens from infinity-1:2 to 1:2-1:1. It has no moving parts, no helicoid. Its teleconversion is less than 2x.

So for use with the 90/2.5 the macro adapter/extender should result in the best IQ in the 1:2 to 1:1 range (I'm too lazy to test this right now). The Macro Focusing Teleconverter will give you a wide focussing range (infinity to 1:1 for the 90/2.5) on a lot of lenses.

I see. Thanks a lot for the complete explanation. Very useful guideline.

After a few more sessions with the Vivitar macro, I'd say it's pretty darn good. It seems well matched with lenses 105mm and below. Not so impressed with those above that, but I'll need some more tests. The first image is with a 28mm Series E. The next two are with a 100mm Series E.

Gaeger, I'd say your examples came out excellent. I find that I seldom use my Vivitar 2x macro for macro work -- more's the pity because it really does work well for this -- but typically I'm using mine with telephoto lenses to achieve even more reach. I've conducted extensive tests with my Vivitar 2x and my various telephotos and I've determined to my satisfaction that it does not deteriorate the images at all, and in some cases it clearly shows that the Vivitar 2x macro TC added to the resolution I was able to capture with my telephotos.


PostPosted: Thu Aug 04, 2011 2:00 pm    Post subject: Reply with quote

After four pages of threads on the Vivitar I'm surprised that no one's mentioned the Teleplus which is also a 7 element macro focusing doubler looking virtually identical to the Vivitar branded version. It seems the Teleplus arrived in camera stores soon after the Vivitar disappeared from them. I'm fairly certain they came from the same manufacturer and I suspect that that was Tokina-Kenko.

I had both versions in Pentax K mount, so a shoot out ensued and I decided the Teleplus had the edge so off to eBay went the Vivitar.

I later picked up a 2x KAX macro Teleplus MC7 which is the KA version, while the manual aperture has 2x APK Macro TELEPLUS MC7 printed upon it.

I have the Minolta mount Series 1 90mm and have converted the matched 1/1 adapter to Sony mount. It was very easy as the mount is quite thick. I took material off and then attached an M42 - Sony-A adapter. But I still can't use the lens for dstance because it still has the Minolta mount and I don't have a NEX yet.

Very interesting! I've never heard of the macro-focusing Teleplus, but I have heard of Teleplus TCs -- didn't know anything about them, though.

Okay, now I'm gonna have to keep my eyes open for TP TCs I guess.

The panagor macro converter is a special converter optimized for macro work
When used with an good 50mm (canon , nikon , olympus , pentax...) the final result is equal or better than a dedicated 50mm macro
I remember a test on french "Phot-Argus" where Nikon 50mm + panagor macro converter result was equal or better than nikon micro-nikkor 55mm 3.5 which was the best macro lens in that period

The final quality is really fantastic


+ 2x other advantage
Maximal reproduction ratio is 1:1 when 50mm lens set at infinity (most macro lenses are 1:2 only)
When 50mm lens NOT set at infinity = Reproduction ratio is over 1:1

lf interested : i sell my om panagor macro converter in "as new" condition (100% mint) + 1.8 om 50mm if you wish (Om accessories/lenses can be easely used on eos)

In the past week I have purchased two of the Vivitar, one in Minolta MD and one in Canon FD. I received the Canon version yesterday. I have removed all the insides except the two helicoid guides and have male and female M42 adapters for it. Off to see an IndyCar Race this weekend. Tuesday I should be done with the work and giving it a test with my El Nikkor 135mm enlarger lens.

I paid $5US for each and S&H of $7.50US and $7.00US. A lot cheaper than the almost $100US + delivery for a new 14mm range helicoid from e*ay. The M42 adapters are simply cheap M42 macro tubes. The Vivitar has a range of ~20mm.

I went and purchased a Hexanon AR 1.8/50 to use with my Panagor converter.

Instead of buying some Vivitar focussing TCs to use as helicoids I've stripped the optics from some broken lenses to remount my enlarger lenses.

I have one of The Vivitar Macro Focusing Tele converters on the way. Looking foward to giving it a try.


PostPosted: Mon Feb 06, 2012 9:37 pm    Post subject: Reply with quote

Couple of days ago i was looking on ebay for some teleconverter for my Nikon D7000, and i hit on this item.The Vivitar 2x Macro teleconverter.I tried to get some info on the net, but i was unable to do so, and actually this is the best source of information i found around, so i decided to register and post on this thread.

So, i want to ask, if this item has more than one versions ( i think it is ) and what are the differences among them.

As far as i red this teleconv is also a fair choise for non macro work, and the samples posted above are fairly sharp i believe.

Also, if i use this teleconverter, on my D7000 (which is a DX Nikon camera) and the Sigma 150mm f2.8 Macro (1:1) , is there a way to estimate the magnification gained?

I see NikonD was selling one, if it is still available please let me know about the price etc.

Thanks in advance,

Theo Kondak

Welcome to the club!

This TC was manufactured in many different mounts, including mount variations (e.g. Pentax K and Pentax K/A with contacts). It was also sold under the "Teleplus" brand: I have two of these in Olympus OM mount, one labeled Vivitar, another Teleplus MC7 (hence we know it's a 7-element TC); they are identical in everything except the markings. In Nikon, I've only seen a single version so far, labeled N/AI (which means Nikon Ai). One thing to be vary of: on some of these units the Ai lug gets sticky and won't work for aperture info transmission. You'd have to disassemble the unit, flush old grease and re-lube it. I did it to mine, works like a charm now.

Thanks for the welcome and for the quick reply.So according to your knowledge, for Nikon there is only one version of this kind of TC right?I know that the old times mostly an item could be in trade under various labels, and vivitar was one of the brands that used to do that.

So as far as i know the Nikon version is 7elements one (a guy was saying about it clearly on ebay). Does that mean that it delivers a higher image quality?

I just received the teleconverter, but i face a really mean problem :S the Teleconverter, has no contacts at all, so the camera body will not recognize the aperture of the lens, so it will shoot on minimum aperture which is way too dark usually.Is there a way to "hack" this issue?
