Dear DPR staff, this may be nitpicking, but: 1/4000th sec is not maximum but minimum shutter speed. Please.
yabokkie: I use EF40/2.8 as "lens cap" that almost as good as some f/2.8 zooms. if this lens delivers as good resolution it could be a good lens cap for XF cameras.
since f/2.8 on APS-C is about 1.3 stops darker than f/2.8 on 35mm full-frame, the price should also be about 1.3 stops lower, or at least at half price of EF40/2.8.
yabokkie,you are confusing the effects of converters (e.g., a 2x converter decreases the aperture two full stops as it doubles the focal length - an f5 100mm lens has a full aperture of 20mm diameter, whereas the same 20mm is only 1/10th of the 200mm focal length you get with a 2x converter, hence you end up with a f10 lens at said 200mm - 4x 'dimmer'). but the same lens used for different sensor-sizes retains the same aperture in all cases as its focal lenght doesn't change. the only thing you do, in effect, is crop your image when you go to a smaller sensor. when you crop an image on your computer, it doesn't get darker, does it? the cause of your confusion lies in your misunderstanding of the recalculation of focus lenghts to full frame. but this is entirely virtual and only done to arrive at an intuitive standard for angle of view. it would be better if we got used to thinking in terms of angle of view directly and skip the full frame reference, but that is another matter.
i see no mentioning of any kind of lens hood for the 18-55mm zoom at all. unavoidably a lens hood would block more of the OVF image than the lens itself does, but i still think a little, nifty lens hood (with length wise 'see through' sides like the one on the X-100) would be nice. especially at the tele end, where there is more reason to restrict the bundle of light reaching the lens to the light that actually reaches the sensor and less blockage of the OVF within the framelines.
DPreview: 'The camera can show framelines in its unique hybrid viewfinder ... (though not, oddly for 50mm).'Fuji announcement for the M-Mount Adapter: '...the OVF displays a bright frame corresponding to the focal lenght in use.'And: 'There are four presets .... plus two optional settings for additional optics.'Putting two and two together, I would say that when one creates a preset for a 50 mm, the corresponding frame will show in the OVF?
