It shouldn't be too much of an issue. The exposure should be fairly forgiving in terms of sharpness, the bulk of the light coming from moving cars after all. It's not the action of the mirror, but camera movement when the button is depressed. A release cable or IR remote would be useful if you have one; otherwise just make sure the tripod is fairly well locked down and be gentle with the shutter release. Oh, and no filters, 'cos they'll cause refraction and generally suck.
I use the self timer for this. Hit the shutter button, camera shakes, timer begins to count down, and by the time the shutter actually opens, the camera's stopped moving.
True i do that also if its for a long exposure shot and even some 1/10 shots as there quite long exposures compared to the other speeds that the cameras can do
Yep, that works too. The only drawback is that if something interesting happens, you're waiting 12 seconds before the camera stars recording. IMGP3910 by silverfish51, on Flickr
Nice what lens you using there , ive got mine set to 2 seconds , i sometimes use it on light streams just click and run away from the camera
It's a Pentax smc FA 50mm 1.4, reverse mounted, paired up with a hot shoe cable, off camera flash and a diffuser. There's a spot on the Towans where the bugs hang out; and carrying your own light means that you can shoot outdoors even when it's overcast.
Very nice. Reverse ring. Screws into the filter thred and allows you to mount the lens backwards. IMG_0288 by silverfish51, on Flickr
