been playing around with my 75-300 lens. mounted on some tripod and noticed that the whole setup (lens and cam) shakes (very slightly) when the shutter opens n closes.
1) at 300mm, will the slight 'vibration' caused by the shutter blur pictures?
2) i dont have a remote release yet, so i used timer instead... any use?
3) will more expensive tripods prevent this? "note the vibration is caused by shutter movement and not by shaky tripod - i think!"
any comments or suggestions are greatly appreciated.
