I don't understand this at all; experience says otherwise.
Could you expand on this?
After 18-months of being used properly you generally have
maintenance issues
to contend with. It is worse if you wear out a shutter assembly
prematurely. I know Canon had a streak of bad shutters that were
taking a
dump just after 15k actuations. It all eats into your useable
lifecycle.
Here is my maintenance costs on my DSLRs:
D60 from 2002 to 2007: $0.00
10D from 2003 to 2007: $0.00
1DII from 2004 to 2007: $0.00
30D 2007: $0.00
You mean repair bills?
Any canned air or wipes for dust removal used?
It's not advisable to use canned air to clear dust out of a DSLR,
especially on the sensor.
The only problem with canned air is when you tip the can, or hold the tip
too close. In that case, it can come out still it its liquid form, which
can freeze things and leave residue. As long as you don't shake/tip the
can...and keep it a reasonable distance from the sensor, you won't have a
problem. I never have. Some people aren't familiar enough with canned air
to know when to expect liquid/freezing effects. Even the most casual of
care will avoid a problem. I usually have a smaller can of it to take on
trips. Be careful with brand new cans, as very little tipping is needed for
liquid to come out.
Interesting side note... I've had a grand total of 3 warts in my life...and
I actually froze each of them off my thumb and the palm of my hand by
dripping the frozen stuff from canned air onto it. You do this by turning
it completely upside down, and just barely pulling the "trigger" until a
drop of the liquid forms at the end of the tube. This way, you can very
carefully control where it goes. Then keep it frozen for a minute or two by
periodically dropping more so it stayes "frosted." It basically kills the
tissue, which then dries up over a period of days...and comes off about like
dried blood from a scrape (that's a nice way of saying, "scab"
). Works
a charm, and is a lot cheaper than having a doctor do the EXACT same thing.
He merely uses a fancier applicator, and perhaps a different chemical that
freezes via quick evaporation. The effect is exactly the same.
Try it...all your warty photography toads!
