What are the best camera lenses to use for portraits and concerts?

Wednesday, January 12th, 2011

I just want to hear your suggestions about what camera lenses to use use if you want to…

Take sharp portraits. A lense that captures face and body well. When you photograph outfits or fashion and makeup pictures.

Secondly, I wonder if there’s any good lense for concert photography? I guess I should look for a tele-zoom. Some people say they make pictures more blurry. Is this true or just a myth?

Thank you.

Good portraits can be taken with any quality lens, however something in the 50mm-85mm range is good on a APS-C sized sensor (ie entry levels & prosumer DSLR’s). I use either a 50mm f1.8, a 50mm f2.8 macro or an 85mm f1.8.

Concert work – well depends on how close you are & how much light there is. If you’re some distance from the stage you’ll need something with some reach – a good general purpose lens would be something like the 18-200mm. If its dark, you’ll need a lens which is capable of wide apertures (ie f2.8). Unfortunately, to get a combination of long reach AND wide aperture costs a great deal!

Tuesday, December 21st, 2010

I just got the Canon EOS 20D from my cousin and she said that I have to buy a lense for it.What camera lenses are recomended for the camera?
What I’m looking for:
Long Zoom
Easy Focus

have a look at Canon EF 70-200mm f/4L USM Telephoto Zoom Lens
- Cheap, compared to other L class lenses.
- Can take in 1.4x extender with little impact on image quality (IQ).
- Very sharp, similar sharpness to its more expensive brothers.
- Very light weight! Other 70-200mm lenses in Canon’s line are heavy

How do you get fungus inside your camera lenses?

Sunday, December 19th, 2010

Hi on e bay on some of the camera Lens wright ups alot of the time it says no fungus or little fungus. My question may be strange but I want to know how do you get fungus on the camera lenses in the first place so I know not to make that mistake with my camera equipment thanks

Fungus comes from warm, damp, dark environments, places like the cupboard under your stairs, or the boot of your car.

To avoid fungus getting on your gear, don’t get it wet. Don’t keep it in the boot of your car or under the stairs. Occasionally shoot without a UV filter, fungi don’t like sunlight.

If you have to store a camera, pack it with a lot of silica gel packs which will absorb moisture, and don’t leave it there for too long.

What is the best way to store camera lenses?

Friday, December 17th, 2010

Hi I want to know what is the best way to store all my camera lenses so I don’t get fungus or damage them in any way. What are the best containers etc to do this with thanks for any advice.

I wouldn’t think fungus would be a factor unless you live in a very wet climate. If you do the same storage as I do should be sufficient.

I keep all my lenses in my camera bag with two cameras. If you can’t keep them there buy a separate bag for each or a larger bag for all. Keep it zipped and in a room temperature location, in the house will work fine.

If you don’t use them often take them out every so often, look them over, perhaps give them a quick dust off and put them back in the zipped case.

By the way I keep a large size women’s makeup brush in my bag. It’s very soft and is great for quick dust offs for camera and lens.

Dyskinesia and Blue Lenses

Thursday, July 8th, 2010

Dyskinesias are uncontrollable involuntary movements particularly affecting some people with Parkinson’s Disease (PD).

This video has been made available in order to widen the awareness of PD sufferers experiencing dyskinesia that blue lens glasses may provide a certain degree of relief for some sufferers.

This video was recorded under medical supervision whilst the person was having a UPDRS assessment in 2003.

Blue glasses do not work effectively for everyone however may be worth trying by anyone suffering with l-dopa induced dyskinesias.

The exact specification for the blue lenses follows. Any optician should be able to make the lenses for you.

TINT — BPI BLUE (2 bottles to 1 quart of water. Must be freshly mixed!!! Tint even
2 days old will not give the appropriate results!!)

LENSES– CR39 PLASTIC (These are standard plastic lenses. You cannot use those light weight lenses -Hi Index or Polycarbonate for this tint! They will not tint properly.)

TIMING–2 HOURS (It will take right at 2 hours in the tint solution for these to be dark enough to be effective.) ***They will be DARK***

INTENSITY–50 % LIGHT TRANSMISSION (These would be classified as sunglasses in the optical industry. This degree of tint **#3 Blue** is dark and may be too dark for individuals with cataracts. Hopefully your optician will be willing to work with you in achieving the intensity you need.)

This specification was extracted from the following website (it is recommended that you visit this website to get some differing experiences/views of blue glasses):

http://www.parkinsons-information-exchange-network-online.com/archive/220.html

As can be seen in the video, staring hard at bright blue paper also helped control dyskinesia for this person.

These are not sun glasses and offer no protection against ultra violet rays. Great care must be taken whist wearing them when moving around as they cut out a substantial proportion of available light. Depth perception may be affected and they should not be used when driving.
