Yo, camera guys, I need some help understanding why my pictures are coming out SO grainy when viewing them on my computer. In general is this a "sensor needs to be cleaned" issue?

Canon XTi w/ 18-55 IS lens
Don't shoot above ISO 100. XTi's so noisy, haha

Yeah its not black dots, it gets progressively worse if you crank up the saturation at all. but even without editing the pics, they're really grainy when i zoom in.

yeah i gotta check to see what settings i shot those pics at. i expect better.
Ehh you can't expect super crisp shots out of the equipment. It's a cheap camera and a cheap lens (both of which I own). Better glass would help out a ton, I never use my 18-55 IS for that reason.

I've seen some of the amazing shots you've taken with an XTi..... so I haven't lost all hope. haha

thanks

*** I should also mention, this is in direct comparison to the shots I used to take with my dad's XTi and older kit lens (non-IS). Those pictures seemed so much better than what these are... I'll check the ISO next time.

Lol, he's gonna need a tripod for that, or fast lenses.

18-55 IS is actually a decently sharp lens, just not necessarily indoors w/o flash.

ISO plays a huge role. Noise reduction in post can help, but generally use as low an ISO as possible. On a sunny day, no need to go above 200 really. When the sun starts going down, past 400 might get you some grain.

Nifty Fifty time Kev!

And why do you have that silver accord in your sig....

be like it is
there are certainly limits, practically speaking, but like the saying goes: "only a bad carpenter blames his tools."

Looking into getting some new lenses with graduation money. I have a Rebel XS, and right now I have the kit 18-55 IS and an EF 75-300. So I'm probably selling the 75-300 and getting a nifty fifty and a 55-200 IS, as seen below.
Canon EF 50mm
Canon 55-250mm IS
Thoughts?
One alternative to the 55-250 IS is anything in the 70-200 range, L glass. f/4 can be gotten for around $600-700.

Another alternative is to search for the 70-210 line of lenses. Better build, faster (lower aperture). The one I had was the 70-210 f/3.5/4.5 Macro. Same filter size as the 18-55.

There's also a 70-210 f/4 that's an older push/pull type zoom.

lol deciding between good lenses and IS at the same price point :lawl:
This^^ I wish I had the money to drop on better glass, IS is what I'm looking at now. Any thoughts on the lenses I mentioned? I know they're not close to the ones Nismode mentioned but I'm mostly just a hobbyist

18-55 IS and the 55-250 IS (nifty two-fifty) are both kit lenses. Good for starting out, you can get pretty good images out of em. Never used the latter, but from when I was using my 70-210, it's the same price practically and it has a better build, focusing window and USM focusing (smooth, full-time manual focusing), not to mention can mount on FF bodies and not just EF-S crop bodies. People who have used both have said they prefer the 70-210. It's the poor man's 70-200 f/4 L (similar range, similar aperture).

Could prob find it for cheaper too. Search online.

As for the 50mm f/1.8, can't go wrong with it. Cheap (in price and build), amazing quality. If you can someone selling the Mark I version, go for it. It'll cost you more, but the metal mount, build quality, better focusing ring, and focus window might be worth it.

^People tend to take advantage and charge an extra hefty premium for it, but there's no reason why you shouldn't be able to find it for less than $200. Over that, you may as well put on another $100-$150 and get the 50mm f/1.4.

Thanks for the input, I really appreciate it. I'll definitely look into the 70-210, hopefully I can get a hold of one before I leave for Mexico on Saturday
