I am seriously thinking about buying this lense but the fact you cannot attach filters puts me off a bit. Has anyone been using this lense and hand holding filters infront, and if so what sort of results are you getting?
For example, in bg2b's photo with the rock in the forground surrounded by yellow leaves (good shot by the way) a grad filter across the top of the shot would bring the foreground to life without loosing the colours in that brighter section.
I like to do stuff in camera.. so looking for any feedback on how people overcome this without getting into a photoshop discussion (you can't always bring back blown out highlights)?
I have just created an album with many 7-14mm shots here :
IMHO, one of the best lenses in the native µ4/3 family !
Hi Wilson and Rafael
Great shots! I'm thinking of buying the lens, but I'm wondering about the speed and size. There are other choices; I've been reading about the coming release of the 14mm/f2.5 pancake and of course there is the Oly 9-18mm both which I am also considering. Wilson mentioned that the lens is fast enough for interiors and that is demonstrated by a nice b&w by Rafael. Are there are reasons for a faster wide angle lens? Hard to judge from your photographs, Rafael, because the site doesn't list the technical settings--but for instance the nice view of the square. Was that shot 7mm? Any comments would be greatly appreciated. Thanks,
Traveler - when you get into wider focal lengths, the need for a faster aperture is diminished somewhat. The general rule to achieve in-focus, sharp photos is to use shutter speeds of 1/focal length (so a 50mm lens should be shot at 1/50th of a second - with the m4/3 format you would double it to 1/100th due to the crop factor as well).
with a longer focal length, a faster shutter speed is needed to achieve a sharp image, but this also contributes to the amount of light coming into the lens. If you were using the 45-200mm at 200mm, you need to shoot 1/400th to get a sharp image - there is no way you could shoot at 1/400th indoors though, the image will be dark.
with the 7-14mm, however, you only need shutter speeds of 1/15th-1/30th to achieve sharp images - these shutter speeds are also typical for a reasonably lit indoor scene.
So, having a constant f4 lens is nicer than the 4-5.6 that will be on the 9-18mm (constant aperture lenses also help with you are using flashes, especially off-camera flash which require additional setup). With that said, the fast speed is not AS important as it would be on say if there were an option to purchase the 45-200mm as the current f4-5.6 vs a (hypothetical) 45-200mm f2.8 constant aperture lens.
7-14mm is also smack in the ultra-wide category. It is equivalent to a 14-28mm lens in 35mm terms, while the 9-18mm is an 18-36mm equivalent. I have owned both a 10-20mm and 12-24mm lens on my pentax dslrs (which equal 15-30mm and 18-36mm in 35mm terms). I can tell you the 9-18mm would be a more practical focal length if you intend to get the occasional portrait, and would be more suited to use as a walk-around lens. The 7-14mm is definitely more of a specialty lens, designed to get up close while getting absolutely everything in the frame.
14mm pancake that is forthcoming is an entirely different category as well - alot of pentax shooters like to carry pancakes only, and if you enjoy the 20mm alot it is definitely another option, but 14mm (28mm equivalent focal length) is not extremely wide, especially compared to the 7-14 and 9-18 lenses.
