(FT5) An Olympus 15mm f/8.0 super small lens is coming…really f/8.0! http://tinyurl.com/9jbtvoe We just heard from our top sources that Olympus super cheap m43 lens will be a 15mm f/8.0 fixed aperture prime! It has a length of 9mm only!!! ... 鏡長9mm, 我開始感興趣了以下摘錄回覆, 不喜英文者可從此離開 : This rumor reminds me of the 1960′es Zeiss Hologon 8.0/15mm, that was also : made for Leica mount: http://tinyurl.com/8aj98mt : I own the second one, the Zeiss Contax G 16mm F8, but alas can’t mount it on : mft cameras because they have a deep protruding part in the back, which : interferes with the sensor :( : But apart of the fixed aperture and the very light and small design, really : those two lenses will be world apart : it was a 16mm full frame while the : rumored Olympus will be a 15mm, aka a 30mm equivalent. It was the most : expensive Contax G lenses, costing as much as a Leica lens, while the rumored : one is supposed to be the cheapest mft lens. : At F8 and given the large mft DOF, it may also have a fixed focus ? The hyper : focal distance will be at 1.9m, meaning that if you aim at a subject standing : at 1.9m, everything will be infocus from 0.95m up to infinite.. In : compensation, they could make it extremely sharp and it would be a perfect : lens for street photography ! 如果對焦是超焦距固定, 從0.95公尺到無限遠都在對焦內 : I see that you are getting it. f/8 for 30mm eq. is the perfect street : shooting lens. Obviously the aim should be to make a pocketable m4/3, with : good IQ and small price, a daytime outdoors lens. With improved IBIS and high : sensitivity ‘f/8 and be there’. Auto ISO will take care of the rest. : In fact I already use an I-69 28/2.8 always at f/8. All lenses before : multicoating, being prone to flare and lack of contrast, were optimised for : f/8. : Oly has an historical knowledge of lenses you can only dream of, Booo 用機身影像穩定器加上Auto ISO, 可以隨時從口袋拿出來照完美的口袋怪獸?!(笑) : What a great idea! Such a lens can do something not even the pancakes are : good at: Make a truly pocket-able Pen camera! Something you could put in your : shirt pocket, or jeans pocket. Use ISO instead of aperture. Makes sense if : you think about it. : I’ve used fixed aperture lenses before, as long as the glass is good, it’s : no big deal. On Olympus kit lenses, I usually have them glued to f/8 anyway. : I’d buy one. Maybe two. : “f/8 and be there.” I’m in. This has the potential as a awesome, daylight : street photographers lens. Cheap, tiny, pocketable, good focal length, huge : DOF, likely to be fixed focus. Autofocus and shallow DOF is often worthless : for street photography since most street photographers use zone or hyperfocal : focusing to ensure they don’t miss the shot. Slap it on a cheap, small body : like a GF3. You now have the advantages of a fixed-focus P&S you can shoot : from the hip, but with a m43 sensor. --
