Hi,
Still no news yet. Check the company forums... seem like the company are waiting for a US company to place a bulk order before announcing the price... wondering which US company??

Anyway, base on the forums, the external lens of the doublet is make of fluorite with hard coating which is similar to Tak APO.

Have a nice day.

denebman, any more news on this tianlang's 90mm f6.7 fluorite doublet? is it released yet? how much is it selling? where to buy?
Not available yet. my friend checked a prototype and found the lens cell still has something to improve, such as the accuracy and the mechanism to fix the lens, you'd better wait some time until they get customer satisfaction. In fact, Tianlang used to be a lousy brand, they began to improve only recently.

Well I really hope the Chinese manufacturers improve quickly to give the established American and Japanese companies a very hard run for their money! :)

Hi,
I think it best for the McGill to post the price list himself... just in case he decided to change the price... :P

Have a nice day.
