Any Users of this Lens ?

Silverfox1

Recently acquired the Canon 70-200 F2.8 MKII lens and was wondering if any of you folks use this lens with extension tubes for macro or know of persons i could speak to on the forum that does.

Not got that particular lens but I do/have used extension tubes on lenses upto 200mm, what's the issue ?

No issues, was going to purchase the Kenko 3 set extension tubes and was wanting to know beforehand which mm tube and at what FL within this range would provide the best IQ & working distance for finicky bugs.

Little tricky to answer. but think the tendency would be to use all the tubes with the lens at 70mm for the highest magnification (ie near 1:1) or use just the thinnest one or 2 tubes at 200mm to get just slightly closer focus distance (but not much magnification). The latter could be good for butterflies or dragonflies.
If the main requirement is just to get slightly closer focus distances at the longer focal lengths you may find it easier to use an add on diopter (eg canon 500D).
