[QUOTE="Don Kuykendall_RIP, post: 554878, member: 6277"] There are other variables that you are not addressing. The longer the lens the faster the shutter speed needs to be. That is a fact that many people miss. There is one rule that many miss and it is a good rule. [h=1]Reciprocal Rule[/h][COLOR=#000000][FONT=Roboto]The basic premise of the reciprocal rule is that [/FONT][/COLOR][I]the shutter speed of your camera should be at least the reciprocal of the effective focal length of the lens[/I][COLOR=#000000][FONT=Roboto]. If you are confused by what this means, don’t worry – it is really easy to understand once you see it in an example. [/FONT][/COLOR]The difference with DX is the you have to go 1.5 times the length of the lens instead of 1 times. Many shooters go twice the shutter speed and find the results are better. so when you are using the 300mm lens you need to shoot at least 1/450 sec and better at 1/600 sec.
