-Manual and auto modes(unlike some new fangled flashes that just have auto settings only) -Great exposure consistency from onflash electronics. -Head tilts up and down and side to side for bounce flash -The auto mode does not get fooled as easily as the 20d's onboard flash. A white surface will always trick the onboard flash into underexposing calling for exposure compensation. The sunpak gets the same exposures wether the subject is dark, light, or neutral with no fuss. -Low price

-No communication with modern camera's like Canon 20d -No off camera ability like the Sunpak 383(which includes PC cord) -Be careful of voltage output at the hotshoe. The high voltages of older flashes could be a problem with new cameras. My 433D measures just under 4 volts which is under the unofficial 6 volt max. for the EOS line. -

This Flash works great on my Canon 20d DSLR, alot more power and better red-eye control than the onboard pop-up flash. I usually run this flash in auto mode and the camera in manual. I take a few test shots to set the proper Lens aperature value to get a good exposure reading on the histogram, than shoot away. The flash compensates very well under different lighting and subject brightness to get consistent exposures without fuss(unlike the onboard E-TTL pop-up flash). The only downside to this flash is it doesn't communicate with the 20d at all even though it is a Canon dedicated flash. All of the Automatic functions are built into the flash so you have to manually tell the flash ISO and to some degree distance info with the 3 auto settings. This is a great buy for someone who doesn't use flash alot and does not want to spend $170-$400 on a dedicated E-TTL flash or someone who only uses flash in manual mode.

-on camera flash -Just bought a second flash, a Sunpak 383 off ebay to use as the main flash. I will use the 433d as a remote flash, triggered by a remote slave trigger.

Powerful, fast recycling, standard lens covers 35mm - 105mm with ease. Flash output is very well balanced with close up shots not showing excessive flash.

The 433D does an excellent job on my Pentax Super Program. Also use it on a Pentax LX. Very good balance whether the exposure is close up or at a distance. Provides perfect coverage for my Pentax SMC-A 35mm - 105mm f3.5 zoom lens. I do not have the attachment for wide angle coverage and have not had any light fall off on shots taken at 35mm.

Easy to use. Simple calculator. Accurate light sensor.

No zoomhead (unless you get the Tl-8 which is an accessory). BUt never felt that I really needed one though. Shots at 28mm looks OK!

Great flash. Powerful and affordable. Works everytime!

I've used the 433D on my Canon A-1 for 14 years and loved it. It has worked every time! Doesn't wash out close ups and has the punch needed for most distant photo's.

Best value manual camera flash around. Find one used and it will serve you well. It does require a dedicated module to work with the different brands so be sure to get the one you need.

Powerful, reliable TTL metering performance (my version is dedicated for Nikon and used with FE2)

Good for outdoor use and the power allows great depth of field and bounce capabilities indoors, but overkill (size & weight) if to be used for indoor snapshots. Fully recycles in <7 seconds with fully charged nicads, but almost instantly available in most indoor flash situations (requires less than full discharge).
