I'll put up results when I have time to edit the images for something practical. The lenses compared were (1) FA28-105 (pz) (2) 18-55WF (3) K50/1.4 (4) 70/2.4LTD (5) A50/1.7.
First off, at 50mm, I was surprised how well the 28-105 compared to 2,3, & 5. The full frame was well-rendered. The A50/1.7's cool cast coatings made for a bit more contrast. Sharpness was not a lot different across the range. But that's at the center of the range of the 28-105 -- which ought to be expected. At 70mm it is clearly inferior to the 70. But it was still quite good. At 35mm the image rendering was good but there was a lot of color fringing. Though the FA35/2 also showed some (this was from white flowers in bright sunshine), it we a fraction of what the 28-105 produced. While the 18-55 is very good it isn't quite long enough for my work. 28-105 will allow me to shoot in the lens' strong area of 40mm-80mm for best results. Recommendation: The FA28-105 (pz) is a very good lens. At the selling price of around $80 on eBay I can highly recommend it in terms bang-for-buck. And if/when FF comes you'll be happy you've got it. ;-) Would I use it on a pro shoot? Yes. And at the price having a backup copy is not out of the question. Also, for the dancers I've been shooting the 105mm reach works well. I need to go out to about 70mm or there about and this will make the shoots go better. -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
