    F/1.8 lenses. Do they hire lobbyists?

    What is so special about f/1.8 that there are so many f/1.8 lenses? Tamron, for example, just came out with new 35mm, 45mm, and 85mm "Vi DC" lenses in 1.8. Why not f/2? We never hear from f/2?

    I'm waiting for an f/0.7 but just to drool over.

    The f/1.8 lenses have long been the fastest lenses aimed at serious amateur photographers. The major players often also have f/1.4 lenses of the same focal lengths aimed at the pro market. The f/1.8 50mm lens has been the "normal" lens for (D)SLRs for decades, and it is 1/3 stop faster than the f/2 lens.

    I actually do own two f/2 lenses - my rather ancient Leica f/2 50mm Summicaron-R and the recently discontinued Nikkor f/2 105mm DC lens. Both are incredibly sharp lenses, not blazingly fast but then I rarely shot them wide open.

    B&H indicates they are selling five f/2 lenses for Nikon cameras made by Nikon (their 35mm f/2 is an old standby still being made), Yongnuo, Zeiss, Mitakon Zhongyi and Sigma (included in their widely regarded and reasonably new Art line).

    Could it be that f1.8 sounds better that f2 in the same way as £1.99 sounds better value than £2

    Joking aside f1.8 has just become a standard' over the years and so is easily recognised for what it offers by anyone getting into photography. Oddly enough I only have one 50mm left in regular use and that is a Pentax which is a f1.7.
