I'm currently in the process of upgrading to an SLR from my Cannon S5 IS P&S and trying to get some initial gear.
I'm looking to get 3 filters a protection filter a polarized filter and a ND filter and was looking for suggestions.
for the protection filter it seems most people get a UV filter but i cant seem to find any photo results or users who can claim a significant enhancement on a digital camera. so seems a waste to spend extra on uv filtering i don't need. however i do want a multi-coated filter to prevent flare. Can anyone recommend a good quality protection filter. I'm looking for 77mm (i intend to get sizing rings rather than mes with multiple filters)
For the polarized filter I'm trying to figure out if getting a linear filter will affect the auto focus on the Rebel XSi (EOS 450D) I'm familiar with the physics behind polarized filters and have even been guilty of trying to hold my sunglasses in front of my point and shoot but i cant seem to find any consistent information about the AF issue on this model. i would just get a circular one but they are expensive and i figure i might e able to find a nice used linear one on the cheap. overall I'm looking for recommendations i intend to use this mostly for scenic views and in bright light.
last I'm looking for an ND filter. i do lots of hiking and have been fustrated with trying to achieve that "soft water" effect in brighter conditions. i have a few really nice ones from some very overcast days but i just dont have the aperature on that camera for bright light and on the SLR i think i could stop it down but most of the cheaper lenses (particularly the super zoom series) tend to get their best sharpness in the f/8-11 range (shallow DOF not the biggest issue) so i figure an ND filter would be a nice option. does anyone have recommendations for brands or levels of ND I'm looking for something that can get 1/10 - 1/4 shutter speeds in moderate to bright light around f/8 at ISO 100
all in all any help would be nice in tryign to balance cost with quality (id rather spend the extra few bucks to not have to buy new filters later)
