Functions well but not perfect
I'm pleased with this app in general, audio measurement is a great way to measure shutter speeds. Its plenty sensitive and had no trouble clocking my old RB. Love the camera list stuff, my only complaint is the confusing measurement of amount off. Number of stops off is fine but the odd mix of fractions and decimals is just weird. Would much prefer if it was just decimals in the measurement.Show lessJohn.Bob
Great app for shutter estimation on old cameras
This app made it very clear that the shutter was twice as long on all speeds under 1/100 sec. Easy to use. Accurate even at 1/50 using sound. I like the control of doing the analysis yourself instead of the app using some algorithm.
I have not tried with the light adapter. That could very well extend the usefulness past 1/50.Show lessdg13
Wonderful product
This app (plus the Fototransistor-Plug) is great. It makes shutter testing of old lenses very easy. No messing around with oscilloscopes or sound-recording programs on the PC like I had to do before. Once you have done it a few times it becomes very quick and simple.Torkn
Useful for testing analog cameras
A good idea for folks who work with older, analog cameras - the simple idea here is that you can listen to the shutter or, with a simple light sensor available from the author, examine the light coming through the shutter and determine the shutter speed. The app provides a database for you to store results by camera.
There are room for improvements (the application doesn't try and do its own analysis of the data, it's up to you; the application makes assumptions about possible shutter speeds) but those of us who need this kind of application will probably find it useful nonetheless.Show lessEben O
Great App! Finally Something I Can Really Use!
Excellent first version. Audio measurement is excellent for slower shutter speeds. Waiting on the next batch of photo-electric eyes so I can throw away my oscilloscope!
Thanks!!!
Feature request: I would like to be able to adjust the recording duration, as I find the three second window a little bit tight.Show lessWilliamBooth
Waste of money
Crashes when you try to save the waveform. Completely useless.Hbaltz
Brilliant -- get the light sensor plug with it
This is a deceptively simple but brilliant little app. I have used it to measure and plot the shutter speeds on my Mamiya 6 lenses as well as on my large-format lenses. I have also used it on my older SLR focal plane shutters up to the flash sync speed. The best thing I did was to contact the developer to buy one of his little plugs that allows the app to respond to the light through the shutter rather than its sound -- don't hesitate to get one as it makes it a lot easier to make the measurements and to assess them with confidence.Show less__brad_
Awful
Perfect waist of £2. Tried it on 4 cameras didn't work on any of them.rdjackson87
And a Calibration table to boot!
This is an ingenious iPhone App. It does what it says and I've gotten credible readings for a Rollie Twin and a vintage Voigtlander. The interface is fine, but you need to add a camera first. Saving to no camera causes a soft exit from the program. I now have correction tables automatically generated for both cameras. I'll probably add the $16 light sensor for more accurate readings, but I am delighted with what I have. Best, JimShow lessCarharty
