pnoob101 · 02-27-2015, 02:46 AM

Hi,

I am new to DSLR and i wanted to get a reverse ring for this setup to see what I can do with that.

I need some help to find the right product to put this lens on reversed on the K3.

Hope someone will help

Kindly

Tim

Why would you want to use a lens that is mainly for birding to use for macro? It is going to be fairly heavy too.

What is the front thread diameter?

I believe there would be issues with reversing this lens. It's going to be harmful to mount such a heavy lens on its own filter thread...

Maybe lens stacking is s better approach.

Yeah, try lens stacking or macro filters maybe? Or even extension tubes?
But I would still suggest you try a dedicated macro lens. Those older manual lenses (f4) can be found for under $200, and they will serve you will. The f2.8 macro lenses with AF will cost a little more, but I think they have a very fair price, because they really deliver a lot. Great IQ.

I would recommend against extension tubes for a lens this long because it will have not much effect.
You can try this:
Canon 77mm 500D Close-up Lens 2824A001 B&H Photo Video
Don't worry that it says Canon, it just screws into your filter thread and with a 400mm lens you may get closer than 1:1 magnification

(depending on the len's native magnification).

What makes you think that particular lens would be in any way satisfactory?

Besides the wise warnings above, keep in mind that it is a very slow lens and the optics are middling at best (I had the lens relatively briefly in Canon mount). You would be far better off reversing a faster prime lens. Many great older manual focus lenses are available. Sharper, more light for focusing, and far less weight and stress on the mount. Take a close look in Marketplace. The lenses providing relatively close focusing (compared to similar focal lengths) will tend to work best reversed.
