Manual extension tubes

I want to do a little macro photography, not spending a fortune, and I was looking at a set of three manual extension tubes to go with my f50 lens. The price quoted is very low (6.99) so I am tempted just to buy a set and experiment, however if anybody has any comments or advice this would be appreciated

I hope that this question has not been asked many times


Roger

Re: Manual extension tubes

You will lose all electronics on the lens so they only work with fully manual lenses. This means you can't set focus or aperture on ZD lenses. OM lenses are fine.

For easy macro work you could do worse than buy something like a Raynox 150 or 250 adaptor. This works on many lenses, including the kit lens, retains all controls and costs about 35 from Amazon.

This is with Panasonic G1 and kit tele lens, could just as well be with Olympus equivalent.

Re: Manual extension tubes

Milke,

Thanks for the advice - I had not realised that I would lose all the controls - which is a downer, however thinking about it I think that my 12-60 lens (which has mechanical linkage) might only lose the aperture control so I will try the 6.99 version first and then graduate to the Raynox if that does not work

Thanks again

Roger

Re: Manual extension tubes

I'm all manual with my 50mm f1.8 OM and I have no complaints so far. Some of my macro photos can be seen on my Flickr

Re: Manual extension tubes

Thanks Mike and Radar,

I have ordered the cheap adaptor, and will experiment with my present range of lenses - at that price it possible to use it as part of a learning curve and discard it if it's not good enough.

Re: Manual extension tubes

You may have to set "shoot without lens" or similar in the menu as the camera won't know that your lens is there. Probably someone with the appropriate camera can advise.

Re: Manual extension tubes

I thought I should give a progress report:

The adaptor arrived today and my first comment was that it is impossible to use the 12-60 on it , even though the it has mechanical focussing, as the specimen needs to be closer to the camera than the front of the lens.
I tried the F50 which worked well except that the lack of focus ring also made this unusable (just as you predicted Mike) I was about to give up until I remembered that I had some old canon FD lenses in the cupboard, and although I had no suitable adaptor they could be butted up to the tubes and held in place with tape. Worked beautifully and here is a test image of a 16 million year old ant.



Canon FD 50mm lens




Thanks for all your advice

Roger

Re: Manual extension tubes

On the 12-60 I think you will have to use only the 2 end-bits. I don't think you'll be able to get much result from the wide end of the lens. I have to use at least 50mm to be able to get a decent focus distance. 14mm on my 14-42 - Forget it! Just have a play with various rings and see what the best setup is for you.

But; if you've got problems with your 12-60 I can buy it cheap from you ;-) Receiving one on hire on monday but I am afraid that I have to buy it afterwards

Sorry NFS. That lens is on my camera about 95% of the time, I only take it off when I have a need for a specialist lens of one sort or another. In fact it's the one thing that has stopped me (so far) getting a mFT system as I would miss its resolution and quick response.
