Lens info

[Hi-Jack]

Hi All,
I bought me a Sony F828 a few weeks ago but i want to sell it and buy a canon;
As i was reviewing the internet a little i came across loads of lenses...

The one i'm looking for has a decent zoom range...
I've been looking at Canon Zoom Wide Angle-Telephoto EF 28-135mm but how in the hell should i know how much zoom it has...

5X 8X 14X ???
How does one calculate the optical zoom on a lens based on the info above...
Would be great if anyone can shed a lite on that for me...

Thanks in advance.

Hi Jack,
You divide the long end(135) by the short end(28), gives you 4.8x zoom.
We really don't judge zoom by the X factor with an SLR, that figure is kind of a throw-back to video cameras.
It does give you an idea of the range of the zoom, but it doesn't tell you if the zoom is wide angle or telephoto in scope.

Thanks for the info. That helps alot already.
I can see the Canon is one of the most desired camera's...

Thanks allot and congrats on this forum.
Always nice to see people help eachother.
(i have a forum like these for DivX DvD players :-) )

sony F828 has the lens that cover 28-200mm range (in 35mm equiv.)
Canon 10D and Digital Rebel have 1.6x cropping factor, so 28-135mm behaves as ~45-216mm. You won't have the wide angle range compared to your Sony. But that's the advantage of an interchangable lens camera: you can have more than one lens to cover the focal lengths that you need ;)

I bought a DRebel with a kit lens. It gives me wide angle to small telephoto. I also bought a 135mm (fixed focal lenght) lens.

... so even with the relatively "short" 135mm you will have better magnification than you currently have with the Sony.. :wink:

Not Bad.. it is a great lens too (28-135mm)

You did not metnion which Canon you are looking at, but if you get the Digital Rebel with the included 18-55mm lens and the 28-135mm... you'll have longer reach with the 135mm AND a wide lens at 18mm X 1.6 = 28.8 :)


Then you'll need to get that 100-400mm for the LONG LONG stuff :shock: :shock: :shock: :mrgreen:

[Hi-Jack]

Yes, it's the digital EOS 300D i'm looking for.

So, i should buy the EOS 300D with the lens (standard)
and buy the Canon lens with 18-135mm to have
28.8 zoom... correct?

Now you also got me interested in the 100-400 but it sounds expensive :-)
Let's check prizes....

I made another post, what to buy with budget 2.000 Euro.
Let's see what comes out.
This is going to be my 4th Digital Camera so i hope to make the right choice now.... (especially for zoom)

Thanks guys.

because the EFS 18-55 that comes with it is a crappy lens. I tested it at 50mm against my old Canon EF 50 mm 1.8 II and I was shocked.
Get yourself the EF 28-135 mm USM IS instead or anything else you can afford. Take a look at http://www.photodo.com/nav/prodindex.html and at http://www.luminous-landscape.com/reviews/lenses/canon_lenses.shtml before you buy anything.

I would not call it crappy. It is not as sharp as 50mm 1.8, but still okay. Its biggest problem, IMHO, is that it's not fast having only f/3.5-5.6 largest aperture.

Considering the cost of the wide angle lenses --even the cheap ones-- the 18-55 is a heck of a bargain. IMHO it is easily worth the $100.00. Maybe image quality isn't the equal of a 50mm prime, but you will find a day when you'll be kicking yourself for giving up that lens just to save $100.00.

A little update.
I bought the DRebel finally and still looking for lenses.
I got the standard 18-55mm and bought a second one 90-300mm (EF).

good choice?
I'm pretty satisfied with the zoom.

Any other lens is a must have for normal pictures (hillidays and stuff)

thx :-)
