Lens compatibility between XSand XT

[ullyn]

Hello,
I have a Rebel XS with Sigma 28-200 lens and Sunpak PZ4000 flash. If the lens and flash are compatible I wanted to get the Rebel XT. Are they compatible? Should I just get the body and buy a faster smaller zoom like the one in the kit, but faster? Or does it make more sense to just get the kit? Thanks for opinions and advice.

Not sure about the flash, but the lens is compatible. Focal length will be altered by the Rebel XT's crop factor so the lens will shoot like a 45-320mm lens.

It works great with the digital rebel xt.
After reading this i was willing to take the risk!

Just take a multimeter and measure the open cct trigger connector, if less than 250v @ fully charged new battery set (after charging several minutes) then you are ok.
I use my sunpak autozoom 4000 on automode, it has a hotshoe sensor, set the rebel xt to manual mode 1/200th sec and f stop as set ont he flash. Flash now has power and seems ok even at 18mm wide.

Chuck Westfall, Director/Media & Customer Relationship, Canon USA, advises as follows regarding the flash sync circuit of the EOS Digital Rebel XT (EOS 350D):

*****
The EOS Digital Rebel XT uses a modified version of the EOS 20D's shutter unit. Consequently, acceptable trigger circuit voltage for both cameras is the same, i.e., 250 volts. Except for the original Digital Rebel, all current EOS digital SLRs (i.e., EOS-1Ds Mark II, EOS-1D Mark II, EOS 20D and EOS Digital Rebel XT) generate their X-sync signals electronically rather than mechanically. This is why they have higher acceptable trigger circuit voltage ratings than earlier models like the D30, D60, 10D and original Digital Rebel. These older models cannot be modified to achieve a higher trigger circuit voltage rating, since such a modification would require a different shutter mechanism as well as a complete redesign of the supporting circuitry.
