Canon EF 50mm f/1.4 USM Lens was introduced back in June 1993. It is an old lens but many photographers still like it included me. It is sharp, light, and fast. It contains two high-refraction lens elements and one Gaussian optics. It becomes 80mm equivalent with attach to 1.6x crop SLR camera with APS-C sensor like Canon EOS 400D Digital or his brother Canon EOS 40D Digital. It is a wonderful portrait lens.

Tired of a very slow transfer rate using Canon EOS 400D Digital USB 2.0 via EOS Utility (WIA)? Fear no more. Get yourself a generic USB 2.0 memory card reader. It costs me less than RM20. It will certainly faster than using Canon EOS 400D Digital USB 2.0 via EOS Utility (WIA).

There are some situations that you fail to focus in low light environment. And you do not want to use flash. With Canon Speedlite 580EX II, you can get focus lock on object in low light environment but it does flash too. How to enable AF-Assist Beam without flash on Canon Speedlite 580EX II with Canon EOS 400D Digital?

I searched online for quite some time and I got a solution. It is kind of a hack to the Canon Speedlite 580EX II. Anyway, it does the thick that I want. But it has limitation too. It cannot emit horizontal (periphery) AF-assist beam. Only vertical (center) AF-assist beam will be emitted.

How to disable flash and use AF-assist beam only on Canon Speedlite 580EX II with Canon EOS 400D Digital? Change the custom setting on Canon Speedlite 580EX II will do the trick. Change C.Fn-05 Flash metering mode from 0 (E-TTL II / E-TTL) to 1 (TTL). Canon Speedlite 580EX II will not able to perform properly with Canon EOS 400D Digital as TTL is used at film SLR camera. Therefore, it will emit AF-assist beam only without flash.
