How essential is Digital Speed 100MB/s Class 10 500X high speed standard on HX100V?
The store I bought my DSC-HX100V called me after I ordered to tell me the 8 GB media I ordered which was 100MB/s was not high quality enough,and that I'd have to pay $30 more for a 4 GB card with the standard in the subject line to ensure I don't get blurry pictures every 7th to 8th photo. They even went as far as to say, that the preview would not show the problem. Well along I went and figured well if I must, I must. I get the camera, and tested a PNY SDHC card just for kicks to see what happens. 12th photo no problem. Am I home free with this card, or might I not see a blurry picture in 20, 30, 40, 50 pictures? How soon can I know for certain that it is error free enough to avoid blurry pictures? Or must I spend 3 times as much for the card to ensure that I don't get blurry pictures? Has anyone with the above "better" standard still gotten as frequent blurry pictures through no fault of the camera setting or stability of the photographer's place?
Please only photographers who have tested this camera who know the media world chime in, as I'd really like to have some scientific basis for spending more in the future before I do so.
