Greetings! Was thinking of getting my second prime (already got one in my fav. focal length - 35mm DX ~ 52mm) but have no idea what to get (i use the same lens as wide angle by stitching 2-4 images together shot handheld with much higher total pixels). Maybe this questions might give me some ideas, and others in my position. If you were asked what is the one focal length that is your most favorite or the one that you most often use, what would it be? G'day! Stanley. P.S.: It would also be great if you can mention why it is your most favorite and what kind of shots you use it for. P.P.S.: Yeah, and do mention if it is the film equiv or full frame or DX. If it is DX, if possible mention your camera's crop factor too.
