So now I have added the Canon 40D to my photography tools.
I am quite impressed w/ its high ISO performance and AF speed. No wonder it's always
compared to its PRO brother the Canon 1D series and 5D(classic). (Remember the Sacred Cow??? :D)

Now I am wondering if I should use it as a main camera for my sidelines specially when covering wedding events. The 40D's AF is fast and accurate and doesn't hesitate even in low light. It gives me better confidence when shooting people. I have compared it against my Sony A700 last night and it's slightly better. Now, the problem is which lens to use during events. W/ the Alpha system, I am using the A700 w/ the SAL16-80/3.5-4.5 (80mm@4.5!) [price @ ~PHP33T] and the closest range I can find available on the Canon mount is the 17-85 IS USM [price @ ~PHP28T]. Fortunately, I was able to borrow my officemate's unit. To cut the long story short, the Canon can't match the SonyCZ lens =( But the 40D body continues to impress me specially on its high ISO capability. With lesser noise, it is indeed better than A700's 1600.
The Canon EF-S 17-85 (shot w/ A700|SAL1680):
The reviews in FredMiranda's site is quite conclusive.

The next candidate is the Sigma 17-70... but Sigma is another story :D
I think I have to give it to the A700/SAL1680 combo - it's a combo that is quite hard to beat.

So I guess I'll just have to get the Tokina 11-16 (or 12-24) and delegate the 40D for UWA duty ;-)

On fps, here's an excerpt from e-fotografija's review of Canon 40D

"As said before, the rapid fire mode won't be used that often by the camera's target public. Sure, it's fun to play with it and show off in front of your mates, but how often do you really need it? You might go all Tim Page (this translator's favourite war photographer ever) and leave the camera on 6.5 fps all the time, just in case Elvis pops up from somewhere. On the other hand, this means that you'll probably take two shots instead of one, which isn't all that good for the shutter. But then again, the shutter has a life expectancy of about 100,000 shots, so it's not too much of a worry. And in any case, you still have the option of using the sane speed, 3 fps."

Lately, I've been itching on another scope. GAS! Must not give in :D

So I decided to revisit my old Meade ETX90RA which I actually have not used to its full potential yet.

As a terrestrial scope, it has an effective FL (folcal length) of 1250mm. But with an opening of 90mm (3.5in), the effective aperture is a dim f/13. This is the source of my 'itch'. I want experience a scope with a wider aperture. The 'down' side is I have to settle for a shorter eff. FL.
An Orion refractor w/ an eff FL/f of 714mm/7.0 w/ D=102mm(4in) costs about USD900 so I have to stop on my tracks and go the more practical path :D

Here's a sample shot using the ETX90 as a lens, The Moon on APS-C sensor w/o crop.

My plan is to improve the electronic drive of the ETX. Information on how to do it abound @ Mike's Might ETX site. This will keep myself busy and take my mind off those refractors.
In due time, I will get my refractor so I can star hop with my kids. But for now, I'll save some cash :D
