Hello Good People!

I will be getting some bday gifts soon & wanted to steer people towards getting me something I can actually use.
I wanted to get an external flash for my 300D, perferably the 550 (not sure if there is a specific one made for the 300D) & was looking into getting a macro extender for my sigma 105mm for those super jacko close ups.
Any advie out there in dpcland?
Thanks in advance
ooh, yeah, links would greatly be appreciated if possible!

Hiya,

don't know if this is what you're looking for but i got a 58MM AML filter for my Sigma 70-300MM Macro Super II lens and am very impressed with it. It brings my macro focal distance down from 1 meter to under half a meter and the pics are amazing.

It came free with my lens so don't know the cheapest place and couldn't find it on Kelkoo. Sorry!

I am also looking for a flash meter. Any thoughts out there?
Thanks Bio!

or if your looking for economical
try polaris

There is no specific flash for 300D. I´ve very lite experience with flashes but Canon 550 is probably the best hotshue flash you can get. But maybe it would be worth it to take a look at the Sigma flash (dont rember the type name but I think it is 500 something). Almost all the same settings as in the Canon flash for half the price.

Sekonic L-358. Add it to your cart to get an even better price that what is shown... I just got one and it is quite nice. One thing that is cool is that it will measure both the ambient and flash lighting and show you the percentage that the flash is contributing to the total exposure.

And yes, the 550EX is the "big daddy" of flashes for the Digital Rebel. The 420EX is also a very nice flash; you can always add a 550EX later and use the 420EX as a wireless slave in an E-TTL compatible multi-flash setup.

Note that a light meter is typically most useful in a "manual flash" situation (i.e., a 550EX in manual mode or when when working with studio lighting). In E-TTL mode (like when using the on-board or a shoe-mounted Canon Speedlight), the flash power is controlled by the camera for a "proper" exposure -- you typically don't need a light meter to know what aperture to set like you do with strudio strobes, for example.

If you are not worried about budget, check out the Sekonic meters.

L-558 would be an excellent choice. :)

EDIT: Eddy is a few steps ahead of me as always 8-)

All that's missing is a decent spot meter. I'd love to get a decent light meter, but I'm currently struggling with the idea of paying $500 for it...

Although that would be nice (and the L-558 does add a spot meter), I figured I would see how useful the L-358 was and see if I really need the spot meter. I was mostly interested in an incident meter (one that would measure the light as it arrives at the subject -- regardless of the tone of the subject -- since my camera already has a reflected light meter built-in, as does just about every other auto-exposure camera out there...) Plus, the 1D Mark II has a 2.4% spot metering mode, as well as a multi-spot metering mode that allows you to average up to 8 readings...

Spot meter is one of the few things I'd really be interested in it for, the control of a 1 degree spot meter is a whole level above anything in camera, even with a camera with an actual working spot meter. More particularly, being able to use that spot meter with a decent manual flash unit (synced through a PC port)

some good stuff guys.ill look into all the suggestions. I am definitely leaning towards the more economical path as my need for equipment is not professionally based.
Any other ideas would be good.
Any info out there about a good macro filter for the sigma 105mm?

Do you own extension tubes? How about a teleconverter, 1.4x or 2.0x? A 50mm lens? If you have any of these, you already have the means to increase your magnification beyond the 1:1 that the 105 is capable of. I made a chart for max. magnification for my Canon 100mm macro:

It should be valid for the Sigma 105mm macro as well. The stated magnifications are all a little high, maybe 5% or so, because of the method I used to determine magnification. It affected all results uniformly, though, so the munbers are accurate relative to each other.
You can see that with a 2x teleconverter, you can bump you magnification to 2.0x! Add extension tubes, and you're up to 3.0x. You'll find that magnification much beyond 3x gets very hard to manage. If you want outrageous magnification, go to the reversed 50mm (you'll need a "macro coupling ring", available for about $10).
Hope this helps...
07/21/2004 11:30:22 PM · #15
thanks kirbic! Thats perfect. I think I couldnt remember the coupling ring part. I have a 50mm but its ring size is 52mm & the sigma 105 is 58mm. does this make a difference?
07/21/2004 11:45:46 PM · #16
You should be OK with that. You'll need to find a coupling ring with the right thread sizes, or get a 52mm-58mm step-up-ring and a 58mm-58mm coupler. I know the 58-58 coupler is available, I have one.

52mm to 58mm Macro Coupler =]

Wouldn't the smaller ring size on the outer lens be more likely to cause vignetting? I know the difference is only 6mm, but at macro scales those things do multiply quickly.

I bought the Speedlite 420EX for my 300D due to cost considerations. I'll probably end up getting a 550 later on when I neew two flashes for studio shots. The 420EX has been wonderful with the hacked firmware for the 300D. And I still have an arm and a leg.
