Which lenses do you recommend for my Cannon AE-1 program camera should I buy?

Tuesday, March 9th, 2010

I recently purchased this camera. It comes with three lenses. FD 50 mm 1:1.8, 2x teleconverter FD and a 200 mm Macro zoom lenses. Which other lenses would you recommend I purchase? I really know nothing about the camera or lenses. I bought them for a gift for my friend. I want to be sure I have the lenses he will need for all types of picture taking. HELP please!

Personally, I’d want a zoom lens for convenience. You can get something like the 35-70mm for under $30: http://www.keh.com/OnLineStore/ProductDetail.aspx?groupsku=CA070090188650&brandcategoryname=35MM&Mode=searchproducts&item=0&ActivateTOC2=false&ID=&BC=&BCC=&CC=&CCC=&BCL=&GBC=&GCC=&KW=fd%2035-70mm

The AE1 is a good camera but it’s also fairly old. Make sure that you get Canon FD lenses – not Canon EF lenses (which only work on newer Canon models and digital SLR bodies).

In the old photos, in taking their portraits, why do people need to look anywhere but the camera lenses?

Sunday, March 7th, 2010

I don’t get the point on not looking at the camera :P Don’t you just wonder? peopl in the 1800s-1900’s look anywhere but the camera lenses. I find it funny

Styles and looks have trends that come and go. However, the main reason for not looking directly into the camera in those days was that the camera equipment was no where near as sophisticated and fast as today. LONG exposure times were required. The subject had to remain as motionless as possible for a few seconds. It was probably much more natural feeling for a person to be looking at another object rather than directly at the camera during a long exposure. That is also the reason you seldom see anyone smiling in older photos. Trying to hold a smile like that was very difficult and unnatural for the relatively long period of time in which the camera was taking the photo.

What is the history of Vemar camera lenses?

Friday, March 5th, 2010

I think it was a post-WWII Japanese company. They mainly made screw mount lenses. I don’t think the company still exists or possibly it was bought out.

I was able to find a few lenses for sale in a couple places, however, no company info whatsoever anywhere on the web.

What is the difference in Digital camera lenses?

Monday, March 1st, 2010

I want to buy digital camara but an confused about the lenses, Leica (Panasomic), Zeiss, etc. I was looking at Olympus Stylus model but there was no specs on the lens. Someone told me some lenses are glass (Leica & Zeiss) and they are the best. Olympus doesn’t specify if theirs is glass or plastic. Thanks for your time.

Yes, the best lenses are glass, however in a compact digital camera the sensor may not be high quality enough that you could even tell the difference between glass or plastic. The best thing you could do to test image quality is either go to a shop where you can shoot pictures yourself and compare the images to other similarly priced cameras, or look at the reviews on dpreview.com

To answer your question directly, Olympus does not specify whether or not their lenses are glass, however on their website (http://www.olympusamerica.com) they do specify if the lenses are rated ED or not. ED (or Extra-low Dispersion) lenses are likely glass, as there would be little point to coating a plastic lens with ED fluid.

Have scientists ever used trilobite eyes as camera lenses?

Saturday, February 27th, 2010

Trilobites have unique eyes formed from calcite prisms. I heard a rumor that some of these lenses are so well presevered that they could be used for camera lenses.
I should make clear that I am refering to their fossilized eyes.

Well you could but you don’t normally get that kind of detail and if I recall calcite replacement is not likely to occur for soft parts like eyes. There are some amazing looking trilobite eyes in the fossil record but you don’t as a rule use them for more than studying trilobites. Besides they’re so tiny why would you use them for that? (I’m going for an average trilobite. I know some were larger)

who made kitstar camera lenses and filters and what happened to the company?

Thursday, February 25th, 2010

I last purchased kitstar products in the early 80’s.
The camera filters were availible in square and round configurations. They resemble the coken filter line.
I need more than 2 answers

Kitstar is a trademark used by a company that markets camera accessories. It’s hard telling who manufactured said camera since Kitstar is basically just a marketer’s trade name. There’s not much info found on the net about Kitstar.

Will my manual lenses from my old 35mm non-working camera work on a digital slr body camera?

Tuesday, February 23rd, 2010

I have three great working manual lenses from my old Sears SLR 35MM camera. These lenses are Pentex K mount. Will they work on a digital SLR camera body as long as it is also a K mount digital camera.

Yes as long as you get a Pentax dSLR it will work seamlessly. You will be using the lens at manual focus in aperture-priority or manual modes only. Great for those used to the old film SLRs. There is a crop factor to consider due to the digital sensor’s smaller size (compared to a frame of film)so that 50mm is no longer normal but short tele and 35mm is just above normal.

Just one warning though. Check (and research about it) if your K-mount lens has the Ricoh pin. That pin may or may not get stuck in the newer dSLR mount while mounting (it will not mount completely if it gets stuck). Do not force the lens out in case it happens. Just look for the thinnest but sturdy plastic sheet you can find and use it to coax the pin down while you twist the lens out. It would be best to find a way to remove that pin or glue it permanently so it won’t get in the way.

Do the Myspace kids know that camera lenses are supposed to face away from you?

Sunday, February 21st, 2010

I’m sure this question will shock and amaze some people, but it is a fact! Lenses are meant to face away from the photographer!
Wow, Sappy, down girl! I’m not running a photographer breeding program here!

EXACTLY! I’m so annyoyed and completely fed up with all the meaningless "kewl pics" on MySpace. And I don’t know why they post them here. If you’ve seen one MySpace picture, you’ve seen them all. They all look the same. Horrible, pixelated, grainy, underexposed pictures of themselves. Some emo kid takes a horrible pixelated snapshot of himself or herself, then they edit it to death on their computer and have the nerve to call it "photography."

Isn’t it sad? This is what photography is degrading into. Some people don’t like it when I say this, but the truth is that I think a lot of this is because of point and shoot digital cameras becoming popular. People are forgetting how to use a camera. With film, you have to take more time and be more careful with your pictures and get the right exposure, the right lighting and composition, etc. But with cheap point and shoot digital cameras, the emo \ MySpace kids think that an underexposed, grainy picture is just normal. As proof, look at how many questions you see here, where they ask "how do you fix a blurry picture?"

Or actually, they post it like this: "how do u fix a blurry pic?" because they can’t spell either.

Then you add the narcissism, and you get a hundred horrible pictures of themselves. A bunch of horrible pictures of some emo kid in front of a bathroom mirror with the camera tilted, or the camera held at arm’s length above them. Usually because they don’t even know how to set the self-timer on their camera, or because somehow they think those pictures look cool. oops…I mean "kewl." You gotta write and spell like them too.

One of these days, those of us who are into real photography might just have to give up and join them. Let’s all take "kewl pics for MySpace." You have to say it in a whiney teenage emo kid\ valley girl voice too…."kewl pics for myspaaaaace."

I’m on MySpace, but I use it for networking and to keep in touch with my friends. The only picture I even have of myself is just for my profile. Everything else is mostly landscape photos I’ve taken. I don’t take "kewl pics." In fact, I despise that term "pics" because of the fact that it reminds me of the typical MySpace pictures. I only take real pictures or PHOTOGRAPHS. I also love shooting in black and white film, and I develop the film and pictures myself at home. I have a blast with it…definitely a lot more fun than standing in front of a bathroom mirror and taking horrible snapshots of myself.

Okay, I’m finished with my rant. Thanks for giving the chance to get this off my chest :)

EDIT: LOL…Thanks, SappyGoLucky! I call it like I see it! :)
