If you Google "difference f-stop t-stop" you'll find plenty of pages which explain the difference.
In short, f-stops are calculated based on the design of the lens. t-stops are measuring the actual light coming through the lens. So, any lens used at t-1.5 will transmit the same amount of light to the sensor, and thus achieve the same exposure for an image.My flickr

Answer (directly from the link): The Samyang 85mm T1.5 is a manual focus prime lens, this VDSLR (Video DSLR) version has been developed primarily for professional cine / movie making purposes.
Question 2: Are they suitable for photography?
Answer (directly from the link, next paragraph): The Samyang 85mm T1.5 is a manual focus prime lens, designed to give exceptional results at wide apertures. At T1.5 great images can be obtained, which is perfect for portraiture and low light shooting, particularly when mounted on a full frame DSLRs.
Your questions were asking general information, and the link I gave you (first hit from google) provided the information you requested. If you were looking for a review of a specific lens, then you might have mentioned that, not asking what it was.Chris
