Slightly wrong there from what Ive heard there is only one aussie one brit and the others Kiwis. Both boats are NZ made except the hull. Hardly any Americans have even heard of the americas cup. Its all about a rich boys sport. I also find it strange that the last 7 races that they would blitz NZ. Could it be the automated gadget they installed to operate something that would free up a man to help with grinding? I don't think they could just become super humans after one night and then go on to win every race. something is not right there. Some would call it cheating others would call it within the rules I guess.

Best answer!
I use a 70-200l series on a 7d for sports, 7d as its a crop comes eith a built in converter (basically turns it into (105-300).but to get serious you cant beat a prime lense like a 300 or 400mm problem is theyre big dollars!:(
Sigma make dome great lenses for a budget, ie the 50-500 gor around $1000 but u need a monobar just to carry same with the big l series lenses.the lense ur using is gd for convenious but u suffer in picture quality n u will wonder why ur pics dont come out as gd as u see from others.
Ur only as gd as ur equipment will let u be.like driving a 4 cylinder car againt v8s (still goes well just doe

Actually forty years ago I was using a bellows then too to do tiny subjects on 35mm film so this kind of gear has always been part of my kit. At the time it was a different brand as well.

As to an average shot of a flower, I just grabbed what was first at hand to illustrate what the gear can do. I suppose I should have selected something more artistic, smaller and with greater impact, sorry. I'll consider that next time.

I would add too though, that there's not much value to getting too excited about this technology, Nikon no longer makes a bellows and the odd one that still exists made by others is hellishly expensive and used bellows are often hard to find. Today with the increasing resolution of the cameras the bellows is rapidly becoming obsolete it seems. I still have one and use one more out of tradition than out of necessity.

That average picture of the flower in fact could have been done without a bellows. But I often also photograph something like this to illustrate scale when I go really small. Since the bellows is set up already it's easier to use it to quickly do the snapshot.

Still though, it does allow me to capture the odd thing I can't do with just a lens and a few extension tubes.

In terms of macro, this is my macro set up. I use a Nikon D3 or a D800 depending on the subject. Light comes from my Nikon Macro flash, I place two flash heads on the lens and another on a surface usually behind my subject though that also depends on the subject. The flash heads are controlled through the flash commander on the top of the camera. The bellows is a Nikon PB6. The lens is the Nikon 105mm macro. It's all mounted on a Manfrotto tripod with a ball head.

There is no electrical connection between the lens and the camera so everything has to be done manually. I usually set the camera to M and I control exposures by individually adjusting flash intensity and/or adjusting ISO. I have two old Nikon macro lenses that still have an aperture ring, the old 60mm and the 200mm. For those I can set the camera to A and adjust exposure using the aperture ring though even then manual is often less hassle.

As the bellows is extended more and more I also lose a lot of light so sometimes I'll use a mirror to shine sunlight at my subject so that I can focus the rig before taking a picture.

Below is a front and side view of the set up and a resulting image.
