Sorry but I think you ' re wrong . Yes , testing can ' t tell us how well people will go in the championship for real next season , but its huge that Vinales has just jumped on the Yamaha and is already as fast and sometimes faster than Rossi . Its less about the times itself and more that he has the character , skill and adaptability to do that successfully . <| sep |> Plus $ 15 year is highway robbery . Pissing on the customer because you can ' t negotiatefind lower server costs is bad business . <| sep |> You don ' t have to buy OIS lenses , but if you don ' t , you won ' t have image stabilization . The question really is how much you think not having stabilization matters . Stabilization becomes more important with longer lenses . Longer lenses are harder to keep stable and often they might also have smaller relative apertures in the first place , resulting in longer shutter speeds . That said , stabilization can also be useful at low light even with shorter lenses , though in those cases you ' re photographic stationary objects most likely since the shutter speeds will be too long to capture movement . Panasonic 25 mm f 1 . 7 is good as long as it is cheapest of the four Oly 25 mm f 1 . 8 , Oly 25 mm f 1 . 2 and PL 25 mm f 1 . 4 being the other three . The Oly f 1 . 8 is supposedly a bit better and the other two options are just better and generally far more expensive . That said , the 25 mm f 1 . 7 is a good deal at the prices it often is sold at I paid 150 , cheapest after cashbacks I ' ve seen has been 90 I think . It does vignette noticeably wide open , but it ' s not something you cannot correct in post processing . The 20 mm f 1 . 7 is supposedly great and it ' s small , but it has noticeably slower AF than other options I hear . For portraits there ' s the Olympus 45 mm f 1 . 8 and the better and more expensive Panasonic 42 . 5 mm f 1 . 7 . The latter does have OIS and is a bit better lens from what I hear , but the Olympus has been heralded as one of the best deals in MFT so it ' s not a bad lens by any means . David Thorpe said , if I recall correctly , that the Panasonic is worth it if you need OIS or if the price difference is negligible , but otherwise you might just as well use the Olympus one . For wider there aren ' t really too cheap alternatives . The SamyangRokinonwhatever 12 mm are relatively cheap and the Laowa 7 . 5 mm f 2 might be cheap when it comes next year . There is the old Panasonic 14 mm f 2 . 5 which is tiny and can be gotten quite cheaply from Ebay . I think it ' s a passable lens .
