Lens spanner and shutter tester

[prinz47]

Good evening I am lookin for a lens spanner like the one in the photo, long size and with five couples of pins. Once upon a time this tool was sold by Micro Tools, but now no more. I cannot find a seller who have this kind of tool. There is someone who knows where can I find it?
I am looking for a shutter tester too, I tried with vfmoto but the one I bought does not work, maybe I was unlucky. Someone knows if there is another "easy to use" shutter tester for sale?
Thank you very much.

Have you contacted the seller of the shutter tester? Last time I checked, his feedback was immaculate. I bought one of his earlier products several years ago and I was impressed with his communication and helpfulness. If you've had problems with his product, get in touch with him (if you have not already).
Regards,
Brett

Thank you all for informations. About VFmoto I have to specify he gave me a complete refound. He is a honest e bay seller.

If you want you can make a shutter tester to plug into the line-in socket on a PC. It would probably have to be a desktop PC as most laptops have only a microphone socket. I did this and use Audacity software to measure the time points.

I've used the shutter tester Ko.Fe. lists above and found it to work fine. I also have the spanner wrench you have pictured, the one that Micro-Tools used to sell, and I'm not too crazy about it. I find it hard to use and adjust properly, especially for smaller lenses.

I haven't tried it, and have no affiliation with the seller, but there's a light sensor hardware plug-in for the iPhone that supposedly gives accurate, optical-based shutter speeds, when used with the accompanying app. The sensor plugs into the phone's mic jack. Here's the link I found:

This seems more accurate than audio-based shutter speed testing, especially for leaf shutters or older rotary shutters, and would also work for things like the curtain shutter on a Speed Graphic, where there's a variation in slit width, rather than timing differences between first and second curtains.

I'd be interested to know of anyone's experience with this product.

PS: The app mentioned above can function independently of the hardware plug-in device as an audio-based shutter speed tester; the light sensor plug-in is what makes this interesting, and also unchains a person from a PC.

That's the one I was referring to. It works pretty well, especially for shutter speeds from like 1/15th to 1/250th.

Test Equipment by Henry Taber is an interesting source of information.... and he has instructions on a DIY shutter speed tester...

The one I made is a few components on a Veroboard, turns the light into sound - same as the photoplug.

If not this one then very similar, without the LED. You then use an audio program to make an accurate measurement of the timings of the shutter opening and closing, which appear as peaks as the level of light changes up then down again - Audacity measures this to 6 decimal places. So same thing but DIY. I just shine a lamp through the camera as the light source - nice and bright to give good peaks. The Taber one looks interesting but needs calibrating though - who has a known good shutter?
