Do watch out when you use the TLA200 as you can get photographs that tend to be overexposed. Furthermore, manually working with the flash can be very difficult, and I have not come across one single method that works everytime. One method that was suggested, and I have actually tried this, is to set the focal length of the flash one step lower than the lens that is used e.g. if you are using the 45mm, set the flash to 35mm or 28mm. Excellent conditioned TLA200's can be obtained for less than SGD250 off eBay if you are lucky. The TLA140 is not much of an option, but fairly good for fill in flash. It seems that the TLA280 or TLA360 are the only usable Contax flashes, but they look kinda big on the G2. Alternatives are Yashica flashes, and Nikon flashes set to auto mode.
