What can I use to clean my camera lens?

First of all, DO NOT use Q-tips or any other product similar. The fine strands of cotton can scratch the lens surface. It is recommended that you purchase a camera cleaning kit. It is a good investment to keep your camera looking and taking pictures like new. ednote: one of the best investments one can make is to get a skylight or uv filter (if possible), and just keep it on all the time. If you mess up the filter, you can always replace it.

What camera lens is best to use on the flight?

Frequently Asked Questions - Helicopter Services Boston
We recommend a lens of around 35mm. This approximates the field of view of the human eye. As the lens becomes progressively wider the picture will appear further away. Conversely, a telephoto lens narrows field of view and is usually not what you want in your scenic, aerial photograph.

Question: -- What is a Barlow lens and how do I use it?

Telescopes FAQ - How to Setup & Use a Telescope
Answer: -- A Barlow lens is a lens that you use with your eyepiece. A Barlow lens will double (2x Barlow) or even triple (3x Barlow) the magnification of any eyepiece that you attach to it. To use a Barlow lens, remove the eyepiece from the focuser, insert the Barlow and then insert the eyepiece into the Barlow. Remember, though, that a Barlow is best used with low magnification (long focal length) eyepieces.

Can I put more than one filter on my camera lens?

Tiffen Filters FAQs - Tiffen.Com
Yes, you can. Our screw in filters ( except for the the WID types ), are double threaded and can be screwed together. Stacking filters can create different effects and bring out your creativity. The only caution is that as you put more filters on the lens you can create vignetting or the cutting off of the corners of your picture. This can happen more with wide angle lenses. We do not make every filter for this purpose.

A1: Fixed lens cameras have a set field of view and cannot be manipulated to produce a wider or narrower angle. These are generally found as 3.6mm, 4.3mm, 8mm, 12mm, etc.. The higher the number of the focal length, the more telephoto the effect. *However- this has nothing to do with the actual size of the lens itself.

How do different camera lens angles affect what I see?

Hidden Camera Surveillance Australia - Hidden Cameras, CCTV ...
A typical highway lane is about 3m wide. To see the full width of a four lane highway you will want a viewing width of about 50 feet. For the distance behind you, you will want to see at least 10 car lenghts in order to make safe lane changes. If we use a car lenght of 3m for the calculation, you will want to see an area of 15m wide at 30m back. All camera angles will suffice for back-up or rear-view systems. The width at 2m back should be wider than the width of the vehicle.
