Look Up Your Camera’s Lifespan with the Shutter Life Expectancy Database

actuationdb1

When it comes to figuring out our car’s life expectancy, we’ve come to expect a little bit of community involvement. Sure, the car company will tell you that your truck is supposed to last X-number of miles, but if the majority of real owners online disagree, we tend to side with them. But why stop at your car? Why not see what users are reporting about your camera’s life expectancy?

Protect Your Photos by Learning the Sounds of a Failing Hard Drive

External hard drives are a convenient way to store your digital photographs, but they have finite lifetimes and eventually fail. Failing drives have a number of distinctive sounds that can warn you and give you some time to start a data-exodus to a healthier hard drive. Datacent, a data recovery company, has a useful page on which you can listen to some of the most common “bad drive sounds”. These are categorized by manufacturer, and include things like stuck spindles, disk heads crashing, accessing bad sectors, and bad bearings. If your drive makes any of these sounds while your photographs are still accessible, begin evasive maneuversimmediately!

Checklist for Buying Used Cameras and Lenses on Craigslist

Editor’s note: The checklist presented in this post is also available as a text file for you to print out and carry along for reference. This post was first published here.

Almost all of the camera equipment I have ever owned was purchased used. While this isn’t something to be proud of, I do like to think I know a thing or two about cameras and lenses. I have run into the occasional problems with lenses, but I made sure I had the option to return them if they had issues. I have also purchased a few lenses and cameras from people on Craigslist as well and as long as you know what you’re getting and tried it out when you made the purchase, you should be covered. There are a few things that I always check and I’m putting them up here in the hope that you might find some of it useful.

Using SLRGear for Lens Research

slrgearlogoHere’s a useful resource I found a while back that many of you might find helpful. SLRGear.com is a website that conducts comprehensive tests on camera lenses, and publishes them in the form of diagrams and illustrations.

One of the features my friends and I have found most useful is the blur index illustration that it provides. This interactive chart helps you find the “sweet spot” for your lens, showing you where the lens is sharpest as you choose a specific focal length and aperture.

blurindex

From the screenshot above of the Canon 24-70mm blur index chart, you can see that there is a sizable “sweet spot” of sharpness in the center of the frame at 35mm f/2.8. As you move towards the outer edges of the frame, there is less sharpness and more blur. Most of the time you will find that lenses have the largest sweet spot at f/4.0 to f/5.6. If you increase the f-number beyond that, you start losing sharpness again.
