Hi, I've been at photoraphy for quite a while now and can't overcome a long term problem...often when shooting wide scenic photos the far distance is grainy, lacks definition and sharpness, might be hazy...basically lacks definition and looks crap. I always try to shoot to maximise my depth of field, I only shoot Velvia 50 slide film and nikon lenses so I'm not taking any cheapskate steps. I have never utilised filters and wonder if i) should I use a UV filter? ii) could it be the lens? the lens in question has always been inferior in sharpness compared to my others. The one mainly producing the crap results if a Nikon 28-80mm zoom made in Taiwan-it was the first of the lighter weight plastic series not actually made in Japan itself. It's still a Nikon. How do the pro's like :hailuncan, Dobre and so forth get those pin sharp backgrounds where the photo just seems to go on forever and forever??? P.S - I'd love some advice also on the use of UV filters and/or polarising filters. I have Nikkor 20mm wide angle, 105mm micro and the 28-80mm. Camera is an F90X. I use a tripod for every shot!
