focussing to infinity

Hi guys,

I'm shooting a fireworks display tonight, and I need to know how to get the kit 14-42 lens to focus to infinity - am I right in thinking its all the way to the right?

Help greatly appreciated!

Danny

Re: focussing to infinity

Isn't the 14-42 focus by wire, in which case twiddling the ring merely tells a the focus motor which way to go, it wont tell you when you get there.

But at f2.8 and 14mm if you focus on something 20ft away then everything from there to infinity, will be in focus. Even closer at smaller apertures. At 42 mm and F2.8 then you will need to focus on something about 150ft away for the same to apply ('bout 80ft at 5.6).

So I'd set your focus on a convenient window/streetlight etc, swith to mf and keep your fingers off the focus ring.

Good luck

Nick

Re: focussing to infinity

Whether it is to the right (clockwise) or left with a "focus by wire" depends on the settings in the camera which can be accessed within the menu - usually as "dial direction".

Re: focussing to infinity

Focus at infinity (AF or MF) in daylight, turn the camera off, tape the focusing collar on the lens to the body to stop it getting moved, turn the camera back on and set if to MF only.

Re: focussing to infinity

A control on the camera body or on any of the autofocus lenses which simply set the focus on infinity and left it there would be very useful.

In the old days for landscapes it was easy - all you had to do usually was turn the focus onto the stop and there you were.

This would be particularly useful on, for example, the 70-300 which will hunt around all over the place unless it has something bright and "meaty" to lock onto!

Of course if you set the camera to reset the lens on switch off and then set focus to MF then when you switch on again the lens will be set to infinity, so just keeep away from the focus ring and you are there.
