|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!
|Sigma APO Tele Macro 400mm F5.6 Canon
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!
|Rokinon 14mm F2.8 Canon DSLR Lens
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!
