A couple of other photos from a lazy Sunday while waiting for iMovie to finish processing a project (only 3 hours to go). The night scene with the 28mm and the sunset with the 105mm. |

Ben, I have more than a few sensor spots... I really need to buy a pack of sensor swabs. |

Ray is right...the 24mm f2.8 ais and 28mm f2.8 ais are very close to performance twins. ![]() ![]() ![]() ![]() ![]() |

Very nice comparison James. The 24mm 2.8 ais is a great lens. It works well on a crop camera and as Leighton has shown is fantastic on a full frame! Usually the 28mm 2.8 ais costs about $100 more than the 24 in the used market. Now, James you have driven the price up |

I'm with Ray, very nice comparison, not much difference at all. I think perhaps the 28 is a tad sharper though. But if you had images side-by-side, you'd be hard pressed to distinguish which was which. |

Had to shoot this through the back door glass. Todays visitor with the 80-200 4.5 Auto. It was shot at 4.5 the exif was screwed up as I had to get the lens on pretty quick before he flew off. Notice the meal residue on the beak. |

I concentrated on a peak performance f-stop comparison. There is no sharpening, distortion correction, chromatic aberration removal, or any adjustments...just SOC. In general, the 28 has stronger contrast at every f-stop, and is sharper...particularly at wider f-stops. From f2.8 to f4 the 28mm ais has it's greatest advantage over the 24mm ais...at f5.6 to f11 it is pretty much a tie. I know I can bring peak performance to the wider apertures by correcting for the aforementioned items that I did not do for this comparison. |
