With regard to UV protective filters I recommend the following...
- don't skimp on cheap glass on top of expensive L lenses. Consider
the filter to be an extra element on your L lenses so try to get
the highest quality you can afford
- at a minimum make sure you buy multi-coated filters to minimize
internal reflection from the front element of your lens to the
inside surface of the filters. Typically the best ones from Hoya
and B+W allow 99.5-99.7% light transmission through the filter so
less than 0.5% is reflected out. I find this just incredible.
- I used to use Hoya SMC (Super multi-coated) but have recently
decided to switch to B+W MRC F-Pro (4mm thin). I switched because
the German glass is the highest optical quality around (perhaps
overkill for Japanese lenses!), the Hoya are also a little
difficult to clean (they tend to smear and stain with some cleaning
fluids), I prefer the B+W brass rings to the soft aluminium rings
that Hoya use. You can just hear the quality as your screw in the
B+W filter and if you plan to attach other filters on top of the
B+W UV filter the brass threads will probably stand the test of
time.
- every B+W filter is interferometrically tested for plane
parallelism. This process is used routinely by the world’s leading
lens makers, but only rarely by filter manufacturers. They are cut
from a cylinder of Schlott [sic] optical glass (same as is used for
German lenses).
- for your 16-35 you probably want a very slim filter and there are
a few brands that are also have threads on the front so that you
can use your lens cap or add a polarizer. Hoya have a new 3mm
double-threaded filter called the 'Super Pro 1' which is the
slimmest double-theaded filter you can buy. I use a 'B+W MRC
Multicoat' which is 4mm thin and I see no vignetting whatsoever at
16mm but I wouldn't expect to see any an a D60 as it only uses the
centre of the lens anyway. However, when digital goes to full-frame
(1:1) you may be happy you bought a slim filter.
- B+W are typically about 20% more expensive that the SMC Hoya.
Good Multi-coated filters are not cheap: I recently paid $97 for a
77mm B+W UV but I could live with this considering the lens cost
almost $2000. If you're the type of person who only buys L lenses
then you may share the twisted quest for perfection in your UV
filters too.
I buy all my filters from

They have the best prices, excellent service and fast delivery.
Hope this information helps ... sorry for the long winded reply.

I have been out of Photography for 15 years, so please be patient
with my ignorance.
The lenses I am using are as follows:
EF 50 1.4
EF16-35 2.8L
EF 28-70 2.8L
EF 70-200 2.8L IS
I need protective filters for these.
1) Are all UV Protection filters the same or should I only buy
expensive brands?
2) Can I use a circular polarizer on the 70-210
