Awais,

Especially for night photography I set infinity focus during the day and mark the focus ring against a fixed mark on the barrel of the lens. A little bit of tape makes the process easy to remove later if you mark only the tape.

Use a small flashlight to find your marks in the dark and use manual focus against the marks. You may need to bracket the focus slightly until you get used to what works for what lens.

This is a so totally cool and simple idea. I feel so stupid now after trying to figure this out on my own. Thanks!

Awais all i do is find a very distant light...or maybe the moon or a planet (which looks like a bright star) & let the camera do it for me. Its very rare that i cannot see one tiny spec of light somewhere off in the distance. I also use spot focus.

For lightning you should be out around (well thats my preference anyway) f22 which coincidently assists with getting most into focus.

Thank you for suggestions i will try them
i have to work with very limited Aperture as kit lens won't be good above f11 :scratch

Awais,

I must confess that I am pretty loose about focus at distance at night for landscape type shots. I focus the lens manually all the way to Infinity and then back off ever so slightly, maybe 1/8 turn or much less. At at a small aperture, smaller than f8, with a lens focal length shorter than 50mm, I think you will find everything is sharply in focus.

Ziggy's idea is great, but I rarely think of that ahead of the time:dunno

Ziggy's idea's great, but if you miss the daylight and can't find a spec of light like Gus says, simply use small aperture (larger f-numbers) and hyperfocal distance. Use www.DOFmaster.com (http://www.DOFmaster.com) to find exact value for your particular lens.

Thank you :wink
Much Appreciated

Taken with the cheap kit lens. I have found it to be fine. I will use it way smaller than the f11 this photo was taken.

Its the subject mate....NOT the equipment.
