hey guys annex myth here and today I'm gonna be doing a review of the Sony 100-millimeter 2.8 STF [Music] this lens is a maximum aperture of f28 and a minimum aperture of f28 sin 10 different groups including one IDI element and one has spherical element along with an STF element which is basically a neutral density filter which darkens from the outside and then transfers into clear in the middle what this does is it allows for a smoother transition in bokeh elements now because of the STF element what happens is you lose about two stops of light so instead of a 2.8 lens this actually functions more like 5.6 so what you're gonna have to do is you have enough to raise your ISO up or you're gonna have to lower your shutter speed but luckily this lens has is so it makes it a lot easier to still get a tack sharp image with less shutter so this is a full frame lens but on aps-c would be equa
