Mary asks…
Lens flare on digital camera?
I have the Canon SX30IS, and I’ve been seeing a blue lens flare from light sources like the sun and christmas lights. I’ve tried other ISO settings, and cleaning the lens with lens cloth, but there’s been no change. I’m not using a lens hood or any kind of filter. This camera is only two days opened
would a filter work too? if so, what kind?

rob answers:
Lens flare is possible under any condition were the light source is within the angle of view of the lens.
The amount of lens flare is effected by how wide the angle of view is of the lens, how clean the front element or lens filter is and the sophistication of the special lens coatings applied by the lens maker.
The most effective way to prevent lens flare is to 1) prevent light sources from striking the lens, 2) keep the lens perfectly clean, 3) use lenses that have the state of the art lens coating and 4) if you do have lens flare, try to use it artistically to add drama to the shot

Helen asks…
what size is the lens on the Canon Vixia hf s200?
I bought the camera and a accessories bundle and the bundle came with a few lens hoods and filter and it says there 58mm. is this correct, b/c i also ordered a few other lens filter and hoods
will they work?

rob answers:
In order:
Read the Filter Diameter spec:
http://www.usa.canon.com/cusa/consumer/products/camcorders/consumer_camcorders/vixia_hf_s200#Specifications
Yes.
Link to the manual:
http://gdlp01.c-wss.com/gds/6/0300003236/01/hfs20-s21-s200-nim-en.pdf
Refer to the optional accessories available from Canon on pages 205-206. Lens add-ons and filters all have a 58mm spec. Since we don’t know exactly what you ordered 9manufacturer), we can’t be 100%, but if you say you ordered 58mm fittings, then you should be good to go.
The Lens Filter spec is also listed near the end of the manual. See page 210.

Michael asks…
Canon Rebel K2 compatable lenses?
Will the “Tamron Autofocus 75-300mm f/4-5.6 LD with Hood for Canon SLR Cameras lens” work on a Canon Rebel K2?

rob answers:
Any EOS compatible lens will work, however if you stick with Canon lenses, they will still be performing flawlessly in twenty years.
If the lens in question was made before 1987, I will not work the Canon K2

Ken asks…
what brand of lens can be used for canon 400d? and what accesories are a must to buy for the camera?
accesories like uv filter, lens hood, blah blah blah.. etc.. hahaha and how much for the lens and the accesories? (i don’t want to be cheated when i buy them, i dont want to pay a large sum of money)

rob answers:
To answer your first question, I’d recommend buying just Canon brand lenses. Canon is the only camera manufacturer that still has not licensed their electronics technology to any of the independent lens makers. All the other brands have to “reverse engineer” the electronics to make them compatible. Unfortunately, if Canon makes a change on future DSLRs the lenses may not be 100% compatible. It has already happened on some of the older independent brand lenses that some of the early lenses won’t work on some of the newer cameras. If you plan on staying with the same body forever it might not make a difference but if you ever plan on upgrading (and who doesn’t?) you might get stuck with a lens that won’t work with your new camera.
As far as filters go, there has been quite a bit of discussion as to whether to use a UV filter on DSLRs. There are a lot of shooting situations where the flat surface of the filter can cause problems with the autofocus and image quality. This doesn’t happen with film camera because the film isn’t as reflective as the CCD sensors are.
Nikon even says in the D200 instruction manual:
quote…use of a filter is not recommended when the subject is framed against a bright light, or when a bright light source is in the frame. … End quote
If you are going to use a filter make sure it is a high quality, multi-coated filter to cut down on problems.
