Digital Camera Lenses
I need to know of a web page or book that would help me learn about lenses and filters. I only got into photography because I wanted a digital camera. Now I have a Kodak DC260 and going to by a Nikon Coolpix 990. I would like to learn about lenses and filters and the differences and also about using scopes and monoculars? Can you help me?..

Actually I think this site (Imaging-Resource) is among the best for information - but there are other sites that are good too. While there is no dedicated area to lenses & filters (good suggestion though) lens issues are being mentioned more and more in each of the reviews. What you want, however, is only now being recognized by the industry as an issue..

Up until recently the need for top quality lenses was minimal - because digital cameras resolution capabilities were limited. Many digital cameras are being built with very inexpensive plastic lenses built for the the video industry (video cameras just don't need super high quality lenses). The focal length requirements for digital cameras is also more along the lines of video cameras as well. The focal plane area of CCD's is much smaller than 35mm film - and the lenses must be of a much shorter focal length. Top quality short Focal Length lenses are much more difficult to manufacture. Also - many of the manufacturers of today's digital cameras didn't have simple access to higher quality lenses from companies like Zeiss, Canon, Minolta, Nikon.



Canon just announced a 10X zoom with stabilization for digital cameras - Canon makes excellent optics so I trust it will be on-par with their 35mm offerings. Other manufacturers are starting to show specific digital offerings. Digital Camera resolutions are now good enough to require better optics - and the CCD's are getting larger so the need for exremely short focal lengths is waning. Unfortunatly there isn't enough volume to get prices in-line. The Nikon D1 is my dream camera - but with a lens and a few basic accessories it's over 6-thousand US dollars! Eeeek. I have a Nikon F3 & 7 lenses ranging from 20mm to 300mm that's all in Mint condition - but not worth enough to even get the D1 body.



Here's a web site that sells filters..

Tiffen Filters.

I think a close examination of this site highlights the current thinking in the industry....

They have a page dedicated to "Filters for Digital Photography" - which is really a bit lame. While the current spate of digital cameras can benefit from wide-angle and telephoto adapters - the need for filters isn't really any different from conventional photography. In fact this site makes the ignorance-revealing mistake of offering close-up filters for the Sony FD-91 - which already can focus down to about .5 inch! This smacks of a marketing effort to create a need where none exists..

Filters can be used to create many of the spectacular effects heretofore only thought possible with film cameras. Here is an example of a web site that shows Near Infrared Photography with a Nikon Coolpix..

Eric Cheng's Near Infrared Photography.

Of course digital photographers can use polarizing filters, colored filters for B & W (even if the camera is color you can still get nearly the same effect by shooting with the colored filter then converting to grey scale in Photoshop.

This is an old message so I hope you are still around. Are maybe someone else will see and answer.

I have the Canon S3 IS. I added the Canon 1.5 X digital zoom and it was just great.

I just purchased a 3X zoom - it's heavy, not plastic, but metal. Ordered the black plastic (casing) one that looked like the Canon 1.5X - but I was sent this replacements lens - heavy lens - metal casing - digital innovations. I've only taken a few pictures - but they all come out tinged in blue and out of focus. The focus I'm sure is Me, but do I need to turn off the digital zoom or something when I use this 3X lens to get rid of the blue tinges? Any suggestions. I'm a point and shoot expert, beyond that just really want to learn, but reading and digesting is time consuming. Haven't had a lot of time for that.

Thanks for any suggestions...

The problem is the tcon, it's terrible. Most manufacturers limit tcons to x1.7, the only good one above that being the Raynox x2.2 (2020pro), http://www.raynox.co.jp/english/digital/S2is/index.htm Digital Innovations, Opteka, Crystal Optics, any brand that claims the tcon is Pro or High Def etc all are bargain bucket brands with poor quality.....

ION #1: I haven't shopped around, but I found that lens on 1 web site for $270. I didn't see a price on the company web site. Looking at the photo samples, I wonder, will I really get that much more out of the 2.2 than I get with the 1.5? QUESTION #2:..

I would like to buy a widr angle lens for my Mavica CD 200. Any suggestions? Frank Monroe..

Comment #6

I am the wrong person to ask, Frank. I am just beginning, a point and shoot kind of person until I learn more. I like taking pictures at the beach and thought a telephoto lens would bring the boats and birds closer, but other than that, I don't know much yet. I would email "MaxxPower" if I were you; he seems to be pretty savvy. Wish I could help. I hope one day to have time to learn more. I keep my camera instruction booklet out in hopes of that day coming soon! I have some nice shots, but I'd really like to know how to use a setting besides AUTO!..

I have a Canon PowerShot S1 IS 3.2 mega. I am looking to get a lens. I like taking landscape shots. There are sooo many wide angle lenes to choose, I am confused. Thanks, Kim..

Comment #8

Hi Kim, my knowledge is limited, and I have the S3. I wanted a zoom lens because I could never get close enough to what I wanted to shoot, like birds in the water, and boats in the ocean. PLus I am unsteady and cameras, even with built in stabilizers are unsteady to a degree, depending on the person shooting. I do not use a tripod. I bought the canon tele-converter TC-DC58B 1.5X. Very inexpensive and very good.

According to articles on the internet you need a really good wide/wide angle lens:.

Http://photoinf.com/General/Wim_van_Velzen/the_use_of_focal_length_in_landscape_photography.htm.

Http://www.twistedtreephoto.com/lenses%20for%20landscapes.html What I suggest, is see what you need from studying ictures on the web, then see what Canon has to offer. I think there lenses are best with there cameras. Someone who responded to my call for help recommended lenses made by Raynox, and I purchased one, although I haven't had great opportunities to use it yet. I traded in some other brand because that brand really was awful. So do a Raynox search as well. Looking at other work on the internet will give you an idea of what you like to shoot and tell you which type of lens you need.

My canon lens was a match made in heaven, of course, and the Raynox lenses are more expensive, but shop around, find the best price. In the near future I would like a wide angle lens as well simply because I looked at some sights for you and I really like what I see. I am going through a lot of personal stuff right now, but I can't wait to really get out there and play and shoot. Best Wishes to you. HAVE FUN!..
