Just got my 1st roll of Provia 100F back and excited to see my test results. Every shot was taken with the Z-1p mounted on an ARCA B1 ballhead/Gitzo 1349 tripod and focused very carefully (between 1-2 metres). Aperture was set on the lens. Inspection was done through Schneider 4X MC & Cabin PL-8M 8X loupes. Comparsion shots were taken without moving the camera, but switched the lens or filter only. And for the filter test shots, the set focus (almost infinite) was not disturbed at all when changing filters (aperture f8). Here is my observation.
FA100/2.8 Macro: Very very nice bokeh and pretty sharp even at wide open. FA43/1.9 vs M50/1.4: M50/1.4 produced nicer bokeh at f2 and f2.8, but still produce very very subtle bright-ring bokeh (almost non-exist, almost). FA43 had clearly more noticable bright-ring bokeh, and the difference is very obvious even under a 4X loupe. At f2, sharpness is pretty close. At f2.8, FA43 is sharper. FA77/1.8 vs SMC-A70-210/4: The zoom had the worst bright-ring bokeh here. FA77 had much nicer bokeh, and shaper too at f4 (zoom set to 70mm), but still produced subtle bright-ring bokeh (worse than the M50/1.4). B+W vs HOYA CIR-PL (regular): There is no difference in colour and sharpness, absolutely none under the 8X loupe. And the shot without filter is not any sharper either. regards, Alan Chan _________________________________________________________________ MSN Photos is the easiest way to share and print your photos: http://photos.msn.com/support/worldwide.aspx - This message is from the Pentax-Discuss Mail List.
