Hey you... Crops are not yet there!!
Today I was experimentig with focal length and minimum time for shots without tripod. A Friend told me that to know what is the minimum speed to be able to shot correctly should be 1/ N mm. there fore all the shots that I did today with 300mm I did them with 1/350.
It seems to be correct since this are the first sharp pictures I am able to take with it :-) Everything else was compensated with f-stop and ISO.
