The 135/F2 is $900 on Amazon.
It weighs 1.7 lbs and uses a 72 mm filter.
It also does not have IS.

The lens gets great reviews as others have mentioned.
What is your subject matter that you think this lens would suit better than what you have. It should be half the 2.9 lbs of the 70-200.

You have some great lens here some of which I also own.
How often do you use your Canon EF 100mm F/2.8 Macro?

Most inportantly will you use it enough to justify the $$$.

You could just rent one and see if you wanted to take the plunge?

I am just envious of your current collection!

Ray,

Thanks I downloaded the picture and could look at the info.

Wow I have tried to get shots of the moon and even read up on suggestions on how best to do it.

Hand Held great shot.

Thanks for the information, I usually set my Canon at -1/3 EV as well as a starting point.

I did enjoy your photos, such detail.

Cheers!

Thanks for taking the time to share that information.
It is such a dreamy shot.

The photo I am most interested in is the bottom or fourth one.

First it is good to know the Kit or equipment. Camera make and model same for the lens.

Second I like to understand how the shot was made, hand held or supported, f/stop, shutter speed, ISO and any filters used, are helpful information if available.

I am an engineer by education and have read extensivly photographic books so I am interested in these things.

Long night indeed in Portland.

Great shot, what kit did you use at what settings?

Great shots!
Share your Body & Lens along with settings!

It is wonderful how the shadows of thier heads connect!
Great shot, I love both GBH and Big Turtles.

Could you share your modle of body and lens along with the settings for the shot?

I have a 60D, did you get your problem resolved?

I should have read on to page to of this subject and seen that others have answered!

You can cycle through the "Info" button and get different displays.
Try pushing the button and you get the level, and then push again you get a different screen.
One such selection is no display, saves power.

Thanks Bob,

I was typing my 2cents and sent in apparently after your comments but before my computer/browser updated the page!

The top 1/4 could be cropped and the picture would be slightly better. All the color and detail are in the lower part.

are the darker courners intentional?

Wow what a great momemt, good enough to get out of bed for!!

You are correct, the buffer filling problem is camera specific and lessons some what when you get a new and expensive camera. Just in case you need justification for scratching an itch!
