I will be looking forward to learning from all of you - I was surprised by husband and kids with a Canon Rebel XS - and I admit it is VERY overwhelming!
Question:
Looking to buy my second lens sometime soon. Right now all I have is the 18-55 3.5-5.6 VR kit lens.
For the next lens, I'd like to buy something to replace my kit lens as a walkaround lens--but with more zoom
OR
Something that will perform better in low light (faster)
I'd love the 18-200 VR Nikkor but it's a little pricey for me right now. Was looking at this Sigma as an alternative:

Anyone have this lens? Is it vastly inferior to the Nikkor 18-200? I know the Sigma is slower--how much of a problem would this be for a general walk-around lens?
Should I just save up for the Nikkor?

As far as low-light: I know about the 50 mm f/1.8 but it won't autofocus on my D60. Not sure I want to buy something right now that will only manual focus. I'd really love the AF-S NIKKOR 50mm f/1.4G, but again that's getting pricey.
What would you do? Save up, or buy a Sigma?
Thank you very much for the review and info, annewjerz.![]()
I guess I just have to do some pondering and decide for myself... leaning towards getting the 50 mm 1.8 now (might be good for me to learn to manual focus, anyway?) and then saving up for the Nikkor 18-200.
Still mulling it over.
Exposure compensation is not always an easy one to grasp and I still have trouble with it sometimes. The way I try to think about it is this: The camera is going to always expose for 18% grey so if you have a subject that is mostly light tones such as a white sandy beach or snow covered field the reflection of the light will fool the meter that there is way more light than there really is. Consequently it will underexpose the picture so you have to compensate by adding more light by +1/3EV, 2/3EV, +1EV or more in some cases. If you have a subject that is mostly dark tones the camera is exposing for less light than there really is so it will overexpose the picture making your dark tones look washed out and not as saturated as they should. In this case you have to compensate by -1/3EV -2/3EV -1EV or more depending on the compensation. The really tricky part comes when you have for instance a very bright sky and a dark subject. The brightness of the sky will cause the lens to stop down and it will expose for the sky leaving your subject in the shadows. You can compensate for it but in most cases you will end up with a blown out sky. One way to work around that is with a graduated neutral density filter that makes half the frame darker and lets you expose for the subject.
I hope some of that is helpful to you. I am by no means an expert but I recently took an online class and we had to do an assignment for compensation. Experiment with your camera. Find a subject with mostly light or white tones and take a picture. Then adjust your compensation to +1/3EV and take another and keep taking pictures by increasing your EV by 1/3 stop. Take 4 or 5 shots this way and compare them.
Here are the shots I took for the class for white or light subjects. The white door looks grey and dingy the way the camera saw it. But when I compensated by +2/3EV the door appeared as it really was, a bright white...
...You can do the same experiment with a mostly dark tone subject and compensating to the -EV side in several shots and see how the darker tones in your pictures with compensation are more saturated and less washed out.
Sorry this got a little long but I hope it helps you a little with compensation.
Thanks for all that great info! It makes it a lot easier to understand. I'll go reread those links now to make sure I'm understanding this right. It seems to be the opposite of what I thought it should be. Spinetnglr, what online photography class did you take? I've been thinking of taking one too. I'm just not sure I have the time...
The course I took was at betterphoto.com.
You might be able to pick up some useful information on the D90 from Ken Rockwell's site. Some of the things he writes you have to take with a grain of salt
Thanks, I checked it out. It had some pretty decent info regarding the D90 settings.You might be able to pick up some useful information on the D90 from Ken Rockwell's site. Some of the things he writes you have to take with a grain of salt but for the most part the facts he gives are right on and I have learned some things about the D300 by reading his pages on the camera. You can find his version of the D90 users guide here:

He has a very large site with lots to look at and read including comparisons of cameras and such.
Thanks Bob100. I'm thinking maybe he's into Scientology or something?also keep in mind
(1) Ken Rockwell is paid to recommend certain cameras, equipment and websites
(2) Ken Rockwell believes space aliens and their spaceships are here on earth
e.g. http://www.kenrockwell.com/nm/aliens/index.htm
of course (1) and (2) are not mutually exclusive and if you get a good pic of a UFO alien with his advice - big bucks !!

Scientology teaches that a space warlord named Xenu was battling thetans, imprisoned them in a volcano on Earth, etc - I don't remember the exact details, but the basic gist of it is that when you join, they start "auditing" you and the higher you get, the more "engrams" (repressed memories that suck away your powers) you release, and you are ranked at an OT (Operating Thetan) level. Eventually, theoretically, you are "clear" and are told the very secret Xenu story. Your wallet is also pretty clear by now, too!Thanks Bob100. I'm thinking maybe he's into Scientology or something?(Don't they believe in Aliens and that they inhabited Earth or something like that?)
They were nice photos though...
Regarding the exposure compensation thing... basically, you use it when the camera is not able to choose the correct exposure on its own. This usually happens when the photo is mostly black or mostly white, and it tries to over- or under-expose to bring out detail in the black or white area, meanwhile losing detail in other areas of the photo.
EC is necessary sometimes but it's also kind of a "band aid solution" - sometimes you can fix the problem better by getting the camera to do a better job metering right off the bat rather than telling it that it's always wrong. You do this by changing the metering mode; most DSLRs let you choose between spot metering, center-weighted, and the entire frame. Spot metering is best when you're focusing on one bright object surrounded by darkness (like on a Disney dark ride, for example), center-weighted is a good overall choice, entire frame is kind of like the "auto" mode - it does all the thinking itself.
So, spot metering is best for certain situations, but not so good where you might have a variety of brightnesses, like in an outdoor shot. This can sometimes lead to an overall underexposed photo if it metered off one small relatively bright object in the frame.

My memory is a little fuzzy as it's been a little while since I was really keeping tabs on them, but it's a morass of doublespeak and crazy science fiction notions. Check www.xenu.net to see lots of information. Scientology tends to focus on getting celebrities to join as a way to evangelize - plus, celebrities tend to have a lot of money and often are pretty accepting of whatever people tell them, so they're easy marks! Needless to say, IMHO it's all pretty bonkers.
