Wayne.


I cannot remember now whether t'was you or Dennis who lined up a row of new first generation adaptors, took a happy snap and posted it here before sending them off to war in the marketplace. Time doth fly doesn't it.

Hey Phill are you getting one of those?
It would be interesting to see a review of the SGblade vs the Letus Extreme.
By the way, have you used the newly resurrected Cinemek G35?

I guess that's disadvantage of living in the US. Even though my SGBlade has been "dispatched" it will probably be two weeks before I recieve it :(

Crazy question:
I wonder if the Letus Extreme flip module can be rigged up on the Blade?

I have same question... I've got a Letus flip module with 72mm thread. I attach it on old Letus 35. I removed achromat and condenser from the 35a to make it all work. Seems the flip does its own achromat thing. May have to take any achromat out..

Chris.


If there is a glass lens in back of the flip module where the camera lens fits up, it will be likely the appopriate achromat. I don't know whether the brothers put one in the after-market flip module or if it is a separate item the customer orders for a given camera type.

This achromat will likely be in the ballpark of 4+ to 5+ power. Your original achromat in back of the non-flip adaptor would likely have to come out as it will be for a shorter setback, ballpark of 7+ to 10+ power and will focus sharp on some point about halfway through the second prism, well back from the groundglass.

I think the condenser might be able to stay in on the SG's if it is close to the power Quyen and Hien chose for the Extreme/Ultimate.

You might need to set the camera back a little furthur from the flip module or preferably add space in between the front of the flip module and the back of the SG. Then again, Wayne's condenser might have the effect of "drawing in" the camera focus point closer in which case the condenser might need to come out.

Suck it and see is the only remedy here unless Wayne can be persuaded to disclose his design secrets.

On the web images, the SG front-to-back seems slightly smaller but that could be my inferior eyesight at play too.

The brothers' original condenser in the first flip Letus XL was a single element BCX, mounted close-up lens reversed as a condenser. Their whole design scheme, whilst faithful to the original concept, is now a universe of sophistication away from the original Letus flip with its mirrors (no smoke) and adhesive joints.
