Re: Eclair Cameras: Zeiss Zoom T3 vs. Zeiss T2

Q: I've noticed a lot of these lenses on Ebay recently. Naturally the T2's
cost more.  But why?

A: Speed! One and 1/4 stop more light.
The extra price you have to pay for the T2.0 Zeiss zoom comp. to the T3.0
zoom comes from the more complicated construction with more glass and higher

Q: Is the Zeiss 10-100 T2 a superior lens in terms of image quality as
compared to the 10-100 T3 and T3.3?

A: No, the optical quality of the T3.0 version with the red  * is excellent.
The T3.3 version is not multicoated and therefore giving a lower contrast.
