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.

Wow.. you are great. But the info in the link does not answer my doubt.. quite unuseful as they are more to marketing info. I need more in-depth review of the lens..

Hmm.. Then what is the difference between T vDSLR lens with normal camera lenses that we have?? For instance t1.5 vs f/1.4 ?

My Question is still unanswered.. : "Is this lens great for still-life photo shot?"? Ty
Reason of asking: The t1.5 lenses looks extremely cheap..

Question 1: What is the Samyang T1.5 vDSLR lens?
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.

Spend another $100 and get the Nikon f/1.8 lens (G or D) Or buy it used for less than the Samyang.
