Can someone clarify for me what type of camera lens this is? And is it a good deal?

nipsy3

This Tamron AF 18-250mm F/3.5-6.3 Di-II lens is described as a macro and zoom lens. Aren't macro lenses for close-up photography only? Is this some type of all-purpose lens that works well for both? If so would it make sense to have this type of lens rather than seperate macro and telephoto lenses?

Thanks.

Answer
Macro lenses are not just for close up work only. They are good for portraits & other general photography as well, its just that they have the ability to close focus.

The lens you linked to is not a true macro lens as it only magnifies in a 1:3.5 ratio. A true macro lens will reproduce an image in a 1:1 ratio on the film or sensor.

The focal length range would make this lens a good all purpose general lens, but you'll find its image quality will not be as good as say a prime lens for a specific focal length.

Help me with a camera choice! ?

Attention Yahoo users I need some help choosing a new digital camera.

I am limited by several factors so it has come down to 2 choices.

Canon PowerShot A590IS 8MP Digital Camera

or

Kodak 5x Zoom 14.0 Mega pixel Digital Camera w/ Smart Capture

What brand do you prefer for your digital camera use? Would you recommend a Kodak or Canon? Any experience with the above cameras?

Thanks!

Answer
Just saw this Canon A590IS camera at Best Buy and Radio Shack. Think it is a great camera and a best buy. It has a viewfinder, optical image stabilizer, auto focus, and uses NiMH rechargeable batteries.

For expanded wide angle or telephoto capabilities, the A590 IS is compatible with Canon's accessory lens adapters: A small button next to the lens bezel is actually a latch; press it and you can remove the bezel ring, exposing a bayonet mount for accessory lenses. Canon offers the WC-DC52 0.7x wide-angle lens, the TC-DC52A telephoto lens, the 250D 52mm closeup lens separately, along with the LA-DC52G adapter to mount them on the camera. (Note that the wide, tele, and macro lenses all need the LA-DC52G adapter to mount them to the camera. The lenses won't work by themselves.)

There is no one particular place to get great buys, but you may see something above that really helps you find the best buy. Click on the second link in the information above for an example then search for your camera of choice at the upper left. Camera prices at this link change often.

In new cameras, look for a viewfinder (LCD invisible in bright sun), optical (not CCD) image stabilizer, and check battery prices. High mega pixel settings take longer to process and may not be needed unless required for very large pictures. Maximum print size for a 3 mega pixel setting is 8 x 10 inches.

CAUTION Do not overcharge! Batteries can be damaged. Use an automatic two or more hour Energizer Compact smart charger with temperature monitor, trickle charge technology, and safety timer ($9.76) at Walmart. Use pre-charged 2000mAh Duracell ($12.97) or RayOVac ($5.97) batteries (hold charge one year) and a full cycle charge. To preserve battery charge, use the viewfinder.

There are so many cameras out there it is difficult to say which is best, but the second source link will be very helpful as it list most of the cameras out there with prices. The following information should help you know what to look for in a camera.

What gives a camera its picture quality?
The short answer is that it is mostly the skill of the photographer that produces high quality pictures. The lens and camera are very important, but the ability to set the scene, adjust the cameras settings, and hold the camera very still or use a tripod with auto or remote shutter actuation when required is what gets the great pictures.

Lots of great camera tips in this link.

My camera has 5.2 mega pixel, but I use 3 most of the time because it gives great results, is faster, and takes less memory. Also, it only has a 3 x optical zoom and 7 x digital zoom. I never use the digital zoom because making pictures larger works better on the computer. This is an old camera, but everyone is impressed with the quality pictures it takes ... like magic.

Check with the Geeks in several stores and compare prices. Once you select a camera, read all about it in the owner's manual. You can view owners manuals at this link, but will need to Login. http://www.retrevo.com/s/digital+camera ...

The source links show most of the cameras out there with prices and make digital cameras work better with help on cleaning camera and battery electrical contacts.

what do numbers on 35 mm nikon camera lens mean?

best camera lens deals image

Rico

I am confused by what all the numbers mean on a 35 mm nikon camera lens .. for example . .Nikon mount 28-75 2.8 tamron lens .. what do all the numbers mean and what is the difference .. this is very confusing .. thank you

Answer
OK I'll break it down for you, and I'll try to explain everything
So lets hold up our imaginary lens, the Nikon Mount 28-75 2.8 made by Tamron:

Nikon Mount: the technical name for this is called the "F-Mount" and has been in use by Nikon for many years, so you can get great deals on used older lenses

28-75: That is the "focal range" of the lens (in terms of millimeters). It is telling you how wide the pictures can be (28 mm in this case) and how zoomed in they can be (75 mm). Of course, that means that, on this particular lens, you can take pictures anywhere between 28 and 75 mm.

2.8: that is called the "Æ-stop". This part is a little counter-intuitive, but the smaller the number, the bigger the aperture hole is. The aperture hole is what controls light amount of light entering the camera. So a little Æ'ing math:
Æ2.8 will let in more light than Æ4, and Æ4 will let in more light than Æ5.6

However, there is a catch: the smaller the Æ-stop is, the amount of the picture that will be in focus drops off quickly. So on a picture shot at Æ2.8, there will be a very Shallow Depth of Field
[example: http://en.wikipedia.org/wiki/File:Shallow_Depth_of_Field_with_Bokeh.jpg ]
On the flipside, a picture shot at Æ32 will have a much bigger Depth of Field [example: http://en.wikipedia.org/wiki/File:Jonquil_flowers_at_f32.jpg ] <-- that is the 28-75 tamron lens, but on a canon instead.

Tamron: the lens maker.

Hope that helps a little bit :)

Why do my glasses look like a fish eye?

Tyler

I barely ever wear my glasses because I can't stand this. I don't know what kind of glasses I have or anything. I usually wear contacts. When I put them on for the first time, I tripped down the stairs (lol). My contacts seem normal, but it looks like I'm looking through a fish eye camera lens with my glasses.

Answer
BK is right. If you wear your glasses often enough your brain will learn how to deal with the strange distortion. Even glasses of moderate strength will initially give a noticeably different perspective until the visual processing centre of the brain becomes accustomed to them. Contacts give less distortion because they sit directly on the eyes.
