Other people have said it all before. GREAT camera!!!

A fun piece of glass. Probably not necessary as long as you have the kit lens but will take some great shots at the 10mm focal length. Still some distortion to be seen at 17mm, but they DO call it a fish-eye. If you are expecting to use this as a super wide angle, you will be disappointed.

A lot of bang for the buck. Not the fastest or clearest piece of glass. I am using this as a learning tool/stop-gap lens until I can afford/justify buying something higher grade. Macro function works well. Good value and you won't be disappointed if you keep in mind that this is only a $140 piece of glass.

Ok flash. Probably worth the $ at current price. I bought mine at a higher price and if I had it to do all over I would go for the higher power 540. This does not come with a stand and does not swivel. Works great wirelessly using built in flash on K10d as trigger. I plan to get a 540 and relegate this to slave duty.

Got this to take the spot of ny 2gig card. i now have this 8 gig which lives in the camera and a 4g that lives in the battery grip. I would recommend getting no smaller that a 4g card if you plan on taking any amount of pictures at all. Especially if you shoot in RAW.

Cheap insurance. Haven't noticed any change in pictures using this filter.

These work well. I think if I continue to enjoy shooting this tight I will invest in a rai system. Focusing hand held is nigh impossible and the tripod is to slow to set up. I've got some good results using my monopod, but have stil discarded way more photos than I've kept due to focus. This filter set seems to prefer good strong lighting.
