Canon EF 70-300mm f/4-5.6 IS USM
Not compatible with the Canon 1.4X and 2X extenders
Rotating Front element -If planning to use a polarizer you wouldn't want this.
IS - The IS is 3rd generation and will achieve 3 stop adv - Good for hand held shots. Esp at the telephoto end.
300mm at telephoto end.
Canon EF 70-200mm f/4.0 L USM Lens
Fixed size - Size does not change while zooming - I personally like this feature.
Non rotating front element.
L quality glass.
Fixed wide aperture (4) - Good if you use zoom a lot. Other wise after zooming, you might need to change the settings (recompose).
Compatible with Canon 1.4X and 2X converters (With 2X no autofocus unless you want to do the 'tape tricks')
Compared to 70-300mm f/4-5.6 IS USM,
Auto focus is faster.
No IS. (IS version is available - for more $$ :-))
Only till 200mm at telephoto side. Have to use extenders.
Weight is same for both the lenses.
If you use a 1.4X extender, the L lens will become 98-280 f/5.6 which is almost same as the other lens.
It is used mostly in point & shoot cameras which is meant for 'all-purpose'.
The zoom for the point and shoot camera is considered as max telephoto/max wide angle.
Most of the p&s camera max wide angle starts at 28mm. So a 10X p&s means 28-280mm.(280/28 = 10x).
Now for an SLR lenses, term nX is not used. Coz not every lenses are general purpose lenses.
Assume there is a lens 10-40mm is 4X
similarly a 100-400mm is also 4X.
These lenses will be used for different purposes. First one is a super wide angle lens and will be used mostly for landscape photography. Second one is a super telephoto lens and will be used mostly for bird/insect photography.
In a nutshell the X notation is a relative term where as A-Bmm is an absolute term.

So I thought of upgrading my 28-135. I started my research and finaly ended up buying a new lens. Its the Canon EF 17-40mm f/4.0 L USM!!!
Yes.. Now I am a proud owner of a canon famed "L" lens.
The options I had for a general purpose lens were
1. Canon EF 17-40mm f/4.0 L USM (outdoor) + EF 50mm f/1.4 USM (indoor)
2. EF-S 17-55mm f/2.8 IS USM
3. EF 24-105mm f/4 L IS USM
The decision was very hard to make - I would say one of the toughest 'photography' decisions I have made ever :D..
I have read so many reviews, which if I would have spent on my certification materials, I would have scored 200% :-)... Something I learned - (Don't read lot of reviews... You will end up shedding money.) :D
My new lens on my 40D.
--- Factors I considered ---
1. Canon EF 17-40mm f/4.0 L USM (outdoor)
+ -> Color/Contrast, L, Build, Sharpness.
- -> Less zoom range (40mm only), No IS, Low light (Am getting another lens for low light.. oh not now!!!)
2. EF-S 17-55mm f/2.8 IS USM
+ -> zoom range, IS!!!, f/2.8, Sharp
- -> DUST!!!!, Not tt great colors, Very exp and not an L, EF-S.
3. EF 24-105mm f/4 L IS USM
+ -> Dream Lens!, L , Build, Sharpness, Zoom Range, IS
- -> Price, 24 is not wide enough & there aren't much wide options.

Decided to go for Sigma coz of
* Slight price adv (~50$)
* Extra 2mm
Now the next step was to get it from a local store.
I called around 20 stores today including
Wolf Camera, San Jose Camera, Ritz Camera, Kamera Korner, Keeble & Shuchat.
Only in one Wolf Camera, the camera was available. But it was 570$!
Now the options are
* Buy the lens for 570 whose actual cost is 480$
* Get it online - This is the last thing I want to do.
So again I am rethinking of Tokina.
Advantages of Tokina are
* Fixed focal length
* Almost 'L' Quality
Tokina vs Sigma
Current decision is.
If I get Tokina for <500 in any local store, I will buy it.
I have to call all stores again. Oh.. Not today!

Photoshopz there.. but its not free :(. I have been using iPhoto, Graphic Converter and some 'simpler' image editors I got from Download.com. iPhoto is good, but not gr8 as a photo-editor. Graphic Converter has lot of functionalities, but I used to get lost in the middle.
Recently only I discovered Gimp.
Its good for 'advanced' photo editing, its not that complicated and above all its FREE!!!
But not everything with Gimp I like.
Gimp is a X-Windows application and it launches X11. Not very happy about it as I want to keep my Mac clean n fast.
The UI and controls are not superior to Photoshop(But again photoshop isn't free..)
Still, I am very happy with my discovery!
Get Gimp here.

So thought of spending some effort to refine my photographic skills..
Thought of restarting from basics..
Read some where that the best way to improve your photography (Composition mainly) is to switch to black & white photography.. The reason being the errors we make will be more noticeable ( Yeah thats true, Some times colors save you from some one saying aaaah! :) - With Exceptions).
Here is one of the outputs...
Nothing ground breaking. One simple image.
The subject is 'my Piano'.
The topic is Low DOF...
I have tried to keep the rule of 2/3s also...
EXIF Info: Exp 1/8,f/5.6,ISO 1000
I am looking for a wide angle lens... The shortlisted options are..
Sigma 10-20mm f/4-5.6
Tokina 12-24mm f/4
I read good reviews about all three lens...
Canon is removed from the list because of its price (~700$).
Now I have to choose from Sigma and Tokina..
Sigma is wide(10mm) but Tokina has fixed focal length..
I am a bit towards Sigma as of now. But still undecided....
My Current Photography Equipments are -->
- Canon EOS 40D
- Canon EF 28-135mm f/3.5-5.6 IS USM
- PlatinumPlus 6200DX
- Hoya Polarizer
- UV Filter
- Canon S2IS
- Olympus Stylus 850 SW
