What is the difference contained by SLR camera mm lens sizes?
What do the two numbers mean in a lens for SLR digital cameras? For example 8-200mm , 24-85mm, etc.
Is the smaller number or larger number better?
I am looking for a lens which I can zoom really far away, but I am afraid it will be so sensitive, that it would be too shaky.
I also saw some are AF lenses, which I wasnt sure if those be better to go with.
Answers: Basically, they are the minimum and maximum distances. The smaller the number, the more you can gain in your picture. Higher numbers have more zoom. 8-200mm vehicle that at the widest it is an 8mm lens and you can zoom up to a 200mm focal point. Need depends on what kind of photos you will be taking. A good all-around lens could be a 28-300. That let you do wide angle and zoom with a single lense. However, those kind of lenses typically have smaller apetures and let contained by less light.
Consider more than one lens as a single lens does not other serve all needs.
A lens of 300+ typically starts to bring shakey so a tripod would be helpfull, but it is not a necessity if you have a fast shutter speed.
AF is other nice to have.
The differences in the numbers describes the adjustable focal length of the lens. The smaller the low number, the better it is for close-up detail shots, close to getting drips of dew on flowers. The larger the high number, the better it is for getting a close-up of something a long way away. The problem is the focal length of the lenses don't tell the whole story. There's also the lens speed and the aperture settings (both of which are inter-relateecstaticn your case, since you're looking for something to bring far-away objects close-up, you'd want the 80-200mm lens. BE WARNED: Those lenses can be strictly heavy, and your concern about shakiness is well-founded. Best bet is to use a tripod when using that lens. Source(s): Air Force Combat Camera for 3+ years
The numbers refer to the "focal length" of the lens. In other words, how long the "zoom" is. 18 mm would be a wide-angle lens, and 200 mm would be a long telephoto. Stop contained by a store or find a friend that will let you spend just a few minutes zoom around to get a feel for this.
Which is best? There is no right answer. Wide angle is apposite for landscapes and getting everyone in the photo indoors. Telephoto is obedient for, well, zooming far away.
I use a Tamron 18-250mm zoom and approaching it a lot. I have other lenses, but this is the one that's on my camera 75% of the time. If I have to keep just one, this is it!
You're right to verbs about shakiness at long focal lengths. At 250mm on a modern DSLR, you collectively should be using a shutter speed of at least 1/400, preferably faster. This can be a problem in some situations so it's virtuous to find a way to stabilize your lens/camera.
There's always a tripod, but they're a aching most of the time.
If you're looking for a new DSLR, please note that Pentax and Sony enjoy the image stabilization built into the camera, so you get that power with every lens, even the older ones.
Otherwise, you'll be looking for lenses near built-in image stabilization, called Anti-Shake or Vibration Reduction or something similar. These lenses are hot and more expensive than their unstabilized counterparts.
Good luck with your choices!
