Using Ultra-Fast Lenses on DSLR Cameras

Step 6Take Photos!

Take Photos!
Put the camera on your lens -- yes, it is a lot heavier than most DSLRs -- and find something to photograph. There's probably something small nearby.

Depending on your camera and the adapter you used, you might need to tell your camera something about your homebrew lens. For example, some Sony cameras need you to tell them it's ok to take pictures when the body doesn't know a lens is attached.

Without focus, always shooting wide open, there's not much to do. You can vary exposure by changing the shutter speed and ISO "film speed."  The really bright finder image makes it easy to see what you're doing and enough light is admitted to allow fairly fast shutter speeds and low ISOs. You'll be able to take extreme macros handheld in most lighting conditions.

The catch is the images will look like the one shown here -- kind of gray. Yuck!
