EOS Lens reversing adaptor

[lost]

Ok a WHILE back I came across a thread that had a link to a store that carried these in the States. I can't seem to find it again. I have also tried google with no luck.

If you know of a store that carries this please post a link.

I am not talking about the one with electrical contacts.

The only one I could find was on ebay.ie here. http://cgi.ebay.ie/ws/eBayISAPI.dll?ViewItem&category=4687&item=7523901386&rd=1&ssPageName=WDVW

It sure would be nice to find one on this side of the pond. I already have the perfect lens for it.

This one maybe?

OK, it ships from Asia ... but so did your Canon camera, right :wink:

Another option I have heard about is gluing a 52 mm filter to a hollowed-out Canon body cap or rear lens cover ... if you don't mind tinkering.

EDIT ... just read your remark about fixing the sink drain yourself in your sig.line ... what you want is the body cap+filter solution :lol:

THIS is the link (http://www.photo.net/bboard/q-and-a-fetch-msg?msg_id=007m6Z) to the home-made Rolls-Royce of macro adapters :lol:
will even indicate when you have focus lock :shock:
But you will need the reversing adapter as well.

Thanks I wanted something quick and easy before I dump the time into building/rigging the AF version.

The US shipping is more a support your Country thing than anything else. So if noone in the US has it I will go elsewhere.

That's the same one I bought from this seller a few weeks ago. Works like a charm and arrived from China (like most Walmart products) in around 10 days.

While I commend you on your patriotism, I really suspect that most adapters for sale either from US or non-US sellers are actually made in China or Japan:lol:

Sid, does that adapter work both with 52 and 58 mm threads?
Hmm, I might get one myself ... although I haven't been a real Macro fan so far.

No, with that particular one, you have the option of getting an adapter with either 52 or 58 mm threads. I got the 58mm one and have been using a step down ring to reverse an old manual focus canon lens to the camera body. Sometimes I wish I had ordered the 52mm just to avoid using the step down ring. Either way, it's a good product and for $13 (with shipping), it doesnt burn a huge hole in the pocket :)

You forgot Phillipines and Taiwan :D

HEHE I know that 90% of the stuff I buy is from over seas. I just would prefer to buy from a reseller in the states to contribute the 10% markup or whatever it is.

I also believe it is futile and Walmart will be responsible for the demise of America. But then again I don't resent Microsoft for their OS. So I guess I could be considered a little crazy!

Thanks for all the help and I will order the one from ebay for $13.00 with shipping.

I placed the order I will update with pictures.

i just put my 50 lens to lens on my 80-200 and i like the results for the price. shallow dof, though.

Yes, but that would be a different approach ... using a Macro Coupler ring to mount the 50 mm in reversed position on top of another lens.

The reversing lens in this thread does not need another lens, only the 50/1.8 or EF-S 18-55.

Don't know which approach is better, though :confused:

When you reverse the 50mm (or any other) lens to another lens (instead of the body), you are adding that much extension too. With this kind of setup, the working distance is very small (one or two inches IIRC). If you reverse the 50mm direct to the camera body the working distance is around 5-6 inches.
So, I'd say, considering the working distance, reversing direct to camera is a better option.

[Andy_T]

Quite interesting is that you can try this out very easily ... just hold your 50/1.8 or EF-S 18-55 in reversed position in front of your camera (with no lens mounted) and take a shot. Focus by moving closer to the subject.

I can only say that the EF-S 18-55 gives some insane enlargement in the 18 mm setting :shock:

thanks for that. it's good to know.

Ok I decided I couldn't wait for the adaptor so I held my k-mount 50 2.8 in front of my 20D and here is what came out. PS all hand held at 1/125 400 ISO f11.

I think the detail is great. BTW that is the metric side of the ruler. So while not exactly 1:1 it is pretty close. (did metric so us mericans would have to hear you uropeens complain.:lol: )

It was SOOO easy to hold the lens in front because the front rim of the 50mm lens fits EXACTLY into the EF mount. It is actually tight enough that I don't think any light could get through. Pure coincidence though.

[Andy_T]

Not too shabby at all :D

Advantage of using a NON-EF lens for this is that you can actually step it down. Doesn't work with EF lenses (aperture is controlled electronic), so you can only use them wide open.

Good thing I have that NOINK 50/1.8 sitting around somewhere ... :lol:

Andythaler,

You can actually. You have to put the lens on normally. Use AV mode and select the desired Aperature. Press and hold the DOF Preview button while removing the lens. The aperature will stay at the selected f stop.

Is that safe for the lens and/or camera ? :confused:

I have seen it posted many times on different forums and no reports of any problems. I have also done it with my 50 1.8.


The previous statement is no gurantee that damage to the camera, lens, person holding, or building containing the camera will not occur. The user gurantee's not to sue, threaten, or fire bomb the person giving advice.

Interesting procedure, thanks for sharing :D
Still, I might just go with the NOINK lens (they have the same 52 mm thread)

I ordered the 58mm reversing adapter yesterday to play with. Im sure it will take at least a week to arive. In the meantime would anyone like to post some examples using this method and give the distance from the subject to the lense.

Also I have 3 lenses I could probably use, the 18-55 kit, the 50 1.8 and the 28 2.8, what lense do you think would work the best?

[sid]

Here's one I took with an old 50mm FD lens reversed direct to camera:

Ok it came in and here is my first attempt.

What lens did you use and what was your aperature.

I also have one of these adapters on the way and hope I can get more depth of field.

[Andy_T]

He mentioned a K-mount (that would be Pentax, then) 50/2.8 lens.

Andy

man.. I love this forum.. you learn stuff every day!!!
(disconnecting big lens from camera.. turning lens around.. trying not to drop either one while attempting to focus on small object......)

I have a reversing adapter for my old 1967 vintage Nikon F's, and have used it with the 50mm and 105mm lenses with great success. Fortunately, I had a Photomic N prism that would do the metering for me (it's the only part of my old Nikon system that doesn't work now). In reading this thread, I think those old lenses would be the perfect lenses to use on my 20D if I could find a reversing adapter.

What I'm wondering about is how to set the 20D to meter the light coming through the lens. The camera would not, of course, know anything about the lens or the physical setting of the diaphragm (f-stop) on the lens. Any ideas?

[Headcase650]

I believe you use AV mode and it will meter with the available light thats coming through your chosen lens.

[Andy_T]

What headcase said. Works the same way as using, e.g., an M42 adapter (which also doesn't transfer any information about the lens to the camera).

Best regards,
Andy

Yes, It was a pentax k-mount 50 f2, That was at 2.0 because it was handheld. I have not had time to deal with it due to the storm in the gulf.

I will setup a tripod and do a little testing tonight and post the results.
