Possible cheap birding glass

[Romy Ocon]

Just saw this ad at PiPho. I'm not in anyway connected with the seller nor do I know him, thus caveat emptor. For those looking for cheaper high quality glass (albeit MF only), this could be worth a look. Just make sure that the FD-EOS adapter will allow infinity focus.

My lenses are EF and I noticed these are FD. I am interested to buy the 25 and 50 extention tube. Will this work on my 180mm Macro 3.5 L lens with auto focus? Thanks.

Ely, FD lenses and accessories are manual focus only. The FD extension tubes won't work with the EF 180 macro.

Thank you Romy. It would have been a mistake to have bought those extention tubes. Is it advisable to buy the Kenko series extention tubes?

Extension tubes are just tubes without optics, and they move the lens farther from the sensor plane so the lens can focus closer, thereby increasing magnification, at the expense of infinity focus.

Some ETs have wiring that allows the lens and camera to communicate, hence AF sometimes work, and the aperture can be stopped down electronically by the camera (as the camera does with normal lenses). The Canon ETs, as well as the Kenko ETs (as far as I know), have such wiring and are usually preferred.

There are some cheap ETs available for as low as PHP 800 for a set (3 tubes of varying length than can be used separately or as a combo):

These have no wiring, hence strictly manual focus and the aperture needs to be stopped down manually. On EF lenses with no manual aperture control, one needs to mount the bare lens on the camera, stop down the aperture electronically, press the DOF button to make the aperture blades close, remove the lens while keeping the DOF button pressed, then attach the ET to the camera and lens. The aperture will stay at the setting it was stopped down to.

Bottom Line:

1. Go for Canon ETs if cost is no object, for functioning electronics and for gear aesthetics.

2. Go for Kenko ETs for functioning electronics at far less cost.

3. Go for the cheap unwired ETs if you want to save a lot and you're willing to manually adjust the aperture.

hi, it may not fit the mount of your DLSR. I'm not so sure but you may try to borrow first two FD-EF adapters and ext tube for experimentation. FD-ext tube-FD-EF. the length of the FDs will add a few inches/mm to your set up and possibly more magnification on a manual focus . Dont buy yet try it out.

another issue-- you may find you cannot set aperture normally. There used to be a trick with the old EOS EF lens when you need to use one as a reversed lens. You set the aperture first via Av and without turning/powering off the camera you then take out lens. The aperture that you set will be the one set on the detached EF lens. Try at your own risk though. I did try this without using a true reversing ring but only using improvised fittings. This is also the one I tried when I used a digital Kodak (and my powershot too) point and shoot camera with an EOS reverse lens lined up at the end of the zoom of the Kodak. Good magnification but tedious set-up without the reversing adapter
