Shutter speed testing

[macandal]

I am in San Francisco, CA. Is there a local place to have the shutter speeds of my lenses checked? Thanks.

Don't know of hand, but if you have an iPhone you should check out this thread. http://www.largeformatphotography.in...r+speed+tester

Thanks. I sent Gassers an email. Waiting to hear.

Roger, I don't have an iPhone (or a smart phone for that matter).

Thanks.

The guy who wrote that iPhone app is in Germany, but he is also producing phototransistor plugs that you should be able to run into any decent computer's microphone jack and get a reasonably (if not very) accurate shutter speed reading. I have one on the way from Germany now and will follow up in the original thread when it arrives. Well worth the 20-odd bucks he's selling them for if it turns out to be accurate.

Mario,
since you don't have an iPhone, My comemnt in the aforementioned thread may be of interest to you:
"The DIYers amongst you can make your own using e.g. Audacity software and any microphone, or your own simple photoelectric circuit; I made myself one about ten years ago from this: http://www.davidrichert.com/sound_ca...ter_tester.htm
Still works like a charm, although very short speeds can get a bit hard to read."

Or you can still buy the plug if you're not into soldering and just use it with the Audacity software on your computer;
I've been running mine on both Macs and Windows PCs and its straightforward. But I've also just set shutters on my computer's built-in mic (which still works, although with limitations) and that way you don't have to buy anything.

I built my own using parts from Home Depot and Digikey, with the limitations on accuracy described above. Now I use a Calumet tester. It should be accurate, and it's certainly more convenient than the audacity route. They're not inexpensive though.

Is this what you were linking to?

The Calumet testers show up used on Ebay from time to time. Like you said they are not inexpensive. I have found that they usually go for $100.00 to $150.00. Mine works great!
