The DOF may be comparable to f12 on the larger cameras, but f1.9 will always give f1.9's worth of exposure regardless of the format. The criticism is an invalid claim where exposure performance is concerned, which is the usual measure of "low light photographic ability". However, if dpreview actually mean ~aesthetic~ low light performance then they're engaging in sloppy and tautologous journalism. In that situation they referred four times, in different words, to a single item of complaint; 1. "...in terms of DOF..." 2. "...and low light photographic ability..." 3. "...No shallow DOF..." 4. "...no nice bokeh..." Turning one complaint into four still only equals one complaint. Just because dpreview is, photographically speaking, a major internet presence doesn't mean their claims needn't be taken with a grain of salt. They have a tradition of being biased against innovation and non-conformity. Just read their reviews of Foveon and Fuji SuperCCD. regards, Anthony "Of what use is lens and light to those who lack in mind and sight" (Anon) -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
