Originally posted by bigdavephoto I don't know about the 35, but the DA 50 does have a dedicated hood. The part number is RH-RA52. It is a rubber screw on hood. Good luck finding one though.
To everybody saying you don't need a filter to protect the front of the lens; First off, I use a lens hood and a filter to protect the front of my lenses, all of them except maybe one, which is lens hood only. Two, I have been in the desert southwest shooting photos on very windy days and I would prefer to loose a filter then a lens. Third, when is your income is basically 0, yes, zero, you do everything to protect what you have invested in over the years. Forth, I think I have had only one time since moving to digital where the filter on the front of the lens made the photo bad.
Yet the front of our camera lenses are multi coated and rather hard. With a lens hood, scratches on the front element are really difficult to achieve from knocking the lens around..
I used to spend oodles on protective UV filters for my lenses.. I noticed there is a slight (but noticeable sharpness decrease with using them -- more glass, more problems) so I tried without it... that was several years ago. I still haven't scratched a lens. They're more durable than I think many of us give credit.
But really if it works for you go for it! It is your money and your photos.
That said, for testing/comparing IQ of lenses, please remove the filters to see what the lens can really do.. and fasten a lens hood on it!
