Yeah, I’m gonna end this year with a blog entry about more camera pr0n. I tested the Sigma 70-300mm F4-5.6 APO Macro<\/b> for Konica Minolta\/Sony mount; the monster was thicker at the zoom ring and had magnification scales on the outermost barrel. It also had a very nice glittery uh… ribbed finish. APO means apochromatic, for lesser chromatic aberrations (but I wasn’t in a place to get that.)<\/p>\n
Sigma 70-300mm F4-5.6 APO Macro apertures:<\/b>
\n70mm onwards F4.0
\n135mm onwards F4.5
\n200mm onwards F5.0
\n230mm onwards F5.6<\/p>\n
This is way<\/b> brighter than the Sony 75-300mm F4.5-5.6 lens on all counts. At 135mm, the Sony’s brightest aperture is already at F5.6!<\/p>\n
It also had a macro focus switch, allowing close focus until 1:2 magnification between 200-300mm. It took almost 180 degrees of turning to get from close focus to infinity… which was a joy for manual focus, but a painfully slow auto focus. At this class, about every cheaper zoom lens will be slow (except the Sony 18-200mm, because its turn is only about 30 degrees.)<\/p>\n
I got a steady (but not crisp) shot at 1\/30s at 300mm. 4 stops! I then got a crisp shot at 1\/30s at 200mm. 3.5 stops! (Of course, you must cooperate with the camera and wait for the Super SteadyShot bars in the viewfinder to go down to 1.)<\/p>\n
At RM750 in Sg. Wang, it was much more promising than the plasticky Sony lens.<\/p>\n
I also found an all-metal monster, the Tokina 80-400mm F4.5-5.6<\/b> for the same mount.<\/p>\n
Tokina 80-400mm F4.5-5.6 apertures:<\/b>
\n80mm onwards F4.5
\n150mm onwards F5.0
\n280mm onwards F5.6<\/p>\n
It had a big throw (turning from close focus to infinity). It was RM2150 in Sg. Wang. The box was aged. However, seeing both lenses gave me new faith in the Sony Alpha mount.<\/p>\n
Anyway, Happy New Year!<\/p>\n

Okay, so it’s not 2007 yet, but the streets of Jalan Imbi are rife with sprayed confetti already! Okay, okay, so that was from Christmas.<\/p>\n
