terryreid: where do you buy one I have spent 30 minutes looking and all I can find is a 4x ISO 12233 test chart which cast $1,025.00 It states you need a 4x chart size to test upwards of 40 megapixel sensors. I shot a resolving power chart last night with several lenses at F4 F8 & F16 and my Sony 55 1.8 sucks at F4 very blurry I supposed I have a faulty lens or it needs to be sent in. Does anyone know if Sony Pro addressed a problem with a lens or what would my course of action be. Out of all the lenses I tested and I tested it numerous times the only one that was as blurry at F4 as my 55 1.8 was my 24-70 F4 zoom at F4 Many thanks for any input. Terry
Look for B.I.G. RES7.
