Sharpness of Digital Photos

[payn817]

Exactly Scooter. I had a sharpness problem with my 5D, it took an entire day to realize the 1.5 factor, and another half day to realize a filter on one lens was the culprit. Do you have a filter on this lens? It seems a few people have problems with certain filters, depending on the coating and thickness.

You can check out dyxum.com or dpreview.com on their forums for more help on issues, there's alot of KM D owners there, and a huge knowledge base.

Perhaps soon PJ will give us a KM/Sony forum to attract some of that knowledge this way.

I just have always kept a UV filter on it. It's only a 5.6 so a polariser would really make it a dog. I used this lens on my film bodies for 5 or 6 years and it's every bit as sharp on the 7D. I love it with the crop factor. People pay $10,000 for 600mm f4's. I have one stop slower for about $9,500 less. I can live with that. ;)

Don't get me wrong, I LOVE my 5D. It's just that I didn't figure the 1.5 thing into my shutter speed, and it was low light ( i was shooting in a mode). So, when i went and did things properly, razor sharp, just like my film body. The filter I was using was a cheap UV filter. It may need cleaning, I haven't looked at it since removal. Just throwing some ideas out there for the original poster.

Glad to see some more KM owners on here.

edit: Have you tried it with the "beercan" yet? WOAH!!

The beercan?....Behold.....One of the first lenses I bought way back in the day.
