Flower ( and advice please)
Canon 1D MKII, 300mm f4 IS, extension tube set, Manual focus, handheld, f5, 1/200, ISO 320.

Hi All,

I got my extension tubes in the week and today was the first time I have had a play with them (as the big warm thing in the sky decided to show :biggrin: ). I'm really after advice as to the best way to use them. I took this image in my garden with all three tubes stacked, is this the norm?? Will they give me a 1:1 with the 300mm on flies etc??

Any help/advice on the best way to use these tubes with a 300mm would be greatly appreciated, right I'm going over the road to watch the Barn Owl's :wavey:

TIA

Regards

Rob

Rob,

Your best bet is just to use whichever tube, or combination of tubes, give you the working distance/magnification that you require.
The more tubes that are attached the greater the light loss, so it's always preferable to use the minimum amount of extension needed.
I use the set of three 12mm, 20mm and 36mm Kenko tubes and use them singly,altogether or in various combinations really depending on the result I wish to achieve.

Nice vibrant flower image too.

Hi Rob,

Justin has put it well, chose whichever, or a combination that will give you the result you are after, I'm not sure on the close focus on the IS but I think you should be closish with the full set of tubes.

Nice image as well..... :wavey:
