I have some Canon lenses (70-200 f2.8 and 24-70 f2.8) that I want to clean
(optical surface) and want some thoughts on the best way to do it.  They are
regularly brushed before use, have no obvious finger or other marks, but are
showing a slight "haze" when held to a bright light ...

Only one month (but obviously there's only one month's data anyway!)
Seems Canon has taken a far bigger hit from Sony than Nikon in the
Japanese market.  The 400d launch price is apparently $US50 less than
the current 350d price.  Margins are the first casualty of true

I just got a DSLR camera and am finding that frequently when a picture
looks clear at full screen on a 1280 x 1024 average quality LCD monitor,
its flaws quickly become evident once one magnifies it a bit.  I've been
using the Opera internet browser because its the only program ...

I see 3x telephoto and wide angle Tele-Conversion lenses are cheap.
Why dont a lot of people use them?
How does their quality compare to real lenses?
If I get a Canon rebel XT($750) or Nikon D50($700) w/kit, and attach

Using a Canon Rebel XT and was wondering if this is difficult?  Can I
burn out the sensor if the solar filter doesn't work properly?  Are
there solar filters one can buy that are reasonably priced?  Could one
make one?  I'm just using the 17-55 mm lens.  But I thought if I could

I have a D70 (not a D70S) and I can afford to part ex & upgrade to the D80.
Question is, is it worth the expense, I tend to do landscapes & as I'm due
to retire I hope to spend far more time doing photography. What is the
general feeling on the upgrade.

I noted that Zeiss is now making some slr lens for Nikon. Are
those lens still made in Germany, and if so, where? I gather that the
Contact cameras are no longer made; but do you think that they might be
once again made? I think that Nikon copied Zeiss when it made cameras,

Anyone have the EW-83J lens hood for this lens, who could measure the
outside diameter of the hood for me?...would like to purchase the hood
and also a Lowepro lens case that fits lens with the hood inverted on
the lens, so I need to know the diameter the case needs to accomodate!

Take a full frame camera and a 1.6 crop digital.
Put a F2.8L lens on both. Set both cameras to automatic and same ISO and
take exactly the same shot. Will the shutter speed on the 1.6 crop camera
be the same as the other, or do camera manufacturers "tune" the internal

What are your thoughts on Smugmug?
I've subscribed for the 14 day trial. So far I'm enjoying, but I'm trying to
weight if it is worthy to pay for the year subscription.
Also, if you are a member, it would be nice if you could tell what is your

I recently received a replacement *ist DL after I returned my old one
for a non-functioning flash.
However, I'm now seeing (or rather hearing) some behavior from my new
*ist's flash that makes me wonder whether everything is okay.

The rest more little silver consumer P&S models.  Too bad.
