I just got Xti and have no experiences with DSLR camera before. What do you guys think of this lense? It has good ratings.

 

That lens doesn't exist.

Do you mean the 28-135 f/3.5-5.6 IS?

What other lenses do you have, or is this your first?

 

lol this thread got me all excited

 

I thought the same thing, but that would be one BIG A lens.

 

I'd put the over/under at 6 pounds and about $4500 if Canon released such a thing.

 

If I could make up a lens, I'd want it to be at LEAST 17-135 F/2L and maybe throw some IS on there.

i guess what i'm trying to say is I don't think 28mm is very wide for a crop body. But at least the 28-135mm f/3.5-4.6 has IS, but isn't an L.

 

I want a 10-500, F1.8 with IS. And a truck to carry it with.

 

This show i know nothing about lenses so i appreciate if you guys can help me decide.

I have the kit lense but i want a new lense and i found this lense with great ratings/reviews from http://www.fredmiranda.com/reviews/s...7&cat=2&page=1.
I'll be using this as a walk around lense.

 

And Bill Gates to buy it for you.

 

What in particular about the kit lens would you like to improve?

The 28-135 is a halfway decent lens but it's not very wide on your XTi. It's not the usual upgrade path for people looking to improve their kit.

If you're looking to replace the kit lens, look at the Tamron 17-50 f/2.8 or maybe even the Canon 17-85. If you want to shoot longer than the kit can reach, look at the new Canon 55-250 IS to add to your 18-55. There are a ton of options, depending on what you're trying to improve...

 

I looked up Tamron 17-50 and it doesn't have IS. Since i'm a noob, do i really need IS lens even though my XTi already have that function?

i don't think i'll need long range lenses but i think the most i'll need is 135mm lens.

 

On Canons, IS is built into the lens, not the camera body.

 

wish i had one of those.

 

No it doesn't. Canon puts it in the lenses, not the bodies.

Stick with the kit lens until you find it lacking in some respect, then get a lens to fill that gap. That's what I learned from the gurus here

 

as stated in previous posts, the 28 turns into 28*1.6 = 45mm, which is lacking on the wide side. However, if you have one of the kit lenses, you are semi covered on the long end anyway, so it's not so bad.

 

also just to clarify...

28mm on the XTi is still 28mm, but your field of view (what you will see through the viewfinder) will be as if you were looking through a 45mm lens.

 

i used a 100mm lens...god, it's too telephoto for me...i can only imagine at 135....i think my next lens is gonna be a 24-70mm 2.8....i think that'd be the PERFECT walk around lens...it goes wide, it goes zoom...

 

I think you should shoot with your kit lens a while longer until you feel like its really holding you back and you know why it's holding you back.

 

these are good advice but i think i'll rent lenses instead. This way i'll find the lenses i like.

 

I'm looking for a faster lense due to the blurry pix that i took. It might be blurry 'cause i didn't use tripod. I just want a lense that takes sharp, in focus and great image quality.

 

some things for you to consider.

the blur is because the shutter speed is less than the focal length. the only way to keep a subject from blurring is to use a faster shutter speed.

are you shooting stationary or moving objects/subjects?

if they are stationary, then for the most part, you need an IS lens to let you get away with shooting at lower light and slower shutter speeds.

now if they are moving subjects, you need a "fast" lens (with apertures at 2.8 or faster). a fast lens lets you stop action by allowing more light in, thereby letting you use a faster shutter speed.



remember, IS doesnt "freeze" motion, it simply cancels any shake due to handholding the lens at slow shutter speeds. if your subject moves, you will have a blurry subject. a faster lens will let you "freeze" or stop motion, giving you sharper pictures.

the best would be an IS lens with a fast aperture, but they get really expensive.

 

Yeah, let's be a bit more specific about motion blur.
The shutter opens, and closes. Motion blur happens because something in the image moves while the shutter is open. The more it moves while the shutter is open, the more blur you have.

As stated in above posts, it's important to separate motion of camera vs motion of subject or both. IS only helps the former.

You should experiment:
Try shorter shutters - the shorter the shutter is open, the less chance of blur.
Check your posture! Posture is very important! Lean on something stable when you can.

Use higher ISOs! Don't hesitate to crank it up if you have to.
Take a look at this gallery: http://lishutterbug.com/08-05-04-chunhui/
Those are ISO 1600 and 3200 pictures. Are they noisy? Yes. But hell, it's freakin'
ISO 1600 and 3200! They are very acceptable pictures.

shutter = 1/focal length is a traditional guideline. That's the old film formula.
Decent starting point, but see what works for you.

That's a great starter/upgrade lens on your XTi if you want to stay in the ~$300 price range. It won't be super wide on youe 1.6 crop camera.

You should be able to find those at the canon forums or craigslist. Usually people that buy the 40D kit part with the lens. That's what I did.

 

I don't think the XTi has 3200 ISO to relate back to the OP.

My 40D is a lot of noise at 3200, it's acceptable at 1600 especially when I shink it down for web publishing, I'd just never imagine doing a large print with those settings.

Those that have D300's and D3's are lucky, ISO 6400 and it looks good

 

ISO3200 on my 40D is fine. sure its not fantastic like the D3, but its still very usable.

 

i dont usually go beyond 400 for personal reasons. plus, if need be i add fill flash at 1/32 power

 

D3 has pseudo 12800.. right? I've seen those pics at a large prints, and it was unbelievable..

 

really? for me i couldn't imagine just limiting myself to ISO100-400.

then again i prefer to shoot with available light before having to use flash.

 

I think ISO 1600 is great on the 40D, and I'd have no problem printing large, say 16x20.

 

its just personal preference. i try to set limits when i shoot, forcing me to be more creative.

here is a shot i took at mid ISO with low power fill. dont trust the EXIF (its masked by the EXIF of the frame I use). i will dig the actual ones when i get home.

i try to blend the available light with the flash by balancing it out with the ISO. then i fine tune it in post

 

I have this lens and I like it a lot
