Here is a report on the lenses that I own
and use with my Canon DSLR camera.
|
CANON
BRAND LENSES
|
These lenses either were 'kit' lenses that
came with my Canon DSLR camera, or were purchased because
of their reasonable prices for popular use.
|
|
Canon 18-55mm F3.5-5.6 Zoom Lens
This was the 'kit' lens that came with
my Canon DSLR. It is a great general-purpose zoom
moderate-wide-angle to moderate-telephoto autofocus
stabilized lens!
|
|
Canon 55-250mm F4-5.6 Zoom Lens
This was the first extra lens that I
purchased for my Canon DSLR. It is a great
general-purpose zoom telephoto autofocus stabilized lens
-- one that I used quite a bit for astrophotography
before acquiring my Sigma lens!
|
3RD PARTY LENSES
These lenses were picked specifically
because they were specialized for certain purposes, and
because they offer those abilities for a price
significantly less expensive than Canon-brand
equivalents, and sometimes even with superior optical
qualities!

Sigma APO Tele Macro 400mm F5.6 Canon
DSLR Lens
My lens was probably manufactured in
1996 or so, and purchased used from eBay. Due to a
firmware communication change introduced by Canon years
ago, the common for changing the F/stop of attached
lenses was changed from 0x12 to 0x13 --
which meant that all 3rd party lenses like Sigma now
were slightly incompatible with Canon's line of DSLR
cameras from that point on. On my Canon T1i/500D,
this means that I get an error whenever I try to change
the F/stop of my Sigma lens to anything other than
wide-open (F/5.6). Since this lens is superior to
Canon's own 400mm telephono -- especially for
astrophotography -- and is much less expensive, this
trade-off is worth this downside.

Rokinon 85mm F1.4 Canon DSLR Lens
I chose this lens because of its
remarkable speed (F/1.4), and sharpness and lack of
'coma' wide open -- great for astrophotography,
especially moderate telephoto shots like constellations!

I chose this lens because of its
remarkable speed (F/2.8), and sharpness and lack of
'coma' wide open -- great for astrophotography,
especially for wide shots like the Milky Way!

Samyang 8mm F3.5 Fisheye Canon DSLR
Lens
|
I chose this lens because of its extreme
wide-angle 'fisheye' capabilities at a very low cost --
good for astrophotography, especially for wide shots like
the Milky Way!
