I have the std 40-150 zoom on my E1 and whilst its a great zoom the closest focus distance is very long at 5ft ish so I was wondering is there a filter/lens that can be added to bring the focus down to maybe 12" so I can take better and larger close ups shots .

You can add a macro extension tube (EX25).

Hi everyone!

If you are a philistine like me you could find a cheaper option is an add on "Macro lens filter" which screw on the front of you lens - I have one which came as part of a cheap wide-angle kit which is a +10diopter lens - which should bring the focussing down to that sort of region, you just won't be able to focus to infinity with it still on. I have somewhere got some trial pictures take with it fitted to my 4/3 14-42mm kit lens where it would allow me to have the lens about 3" away from the object and it would autofocus correctly.

The listing below is for a kit of 4 different macro lenses for under 10, which look similar to the one I've used.

Item number:
130647719555

If I get chance I'll chuck mine on the 40mm - 150mm tomorrow and post up a picture and a detail from it to give you an idea of image quality.

Cheers,

Ralph.

From my experience, It's likely to be pretty poor IQ wise as it's a single element design, but on the other hand if you keep an eye on ebay or similar, you might be able to pick up an Achromatic one by Sigma, Dorr or Canon.
Sigma certainly do a 58mm Achromatic close up lens as I've got one. It's some time since I used it but it was remarkably good at the time.

Here's one now http://www.ebay.co.uk/itm/Sigma-Achromatic-Macro-Lens-58mm-Thread-/221217195637?pt=UK_Photography_Conversion_Lenses&hash=item3381928675 (http://www.ebay.co.uk/itm/Sigma-Achromatic-Macro-Lens-58mm-Thread-/221217195637?pt=UK_Photography_Conversion_Lenses&hash=item3381928675)

There's some usually some useful info HERE (http://fuzzcraft.com/achromats.html) , but it seems to be offline at the moment.

I'll put in a vote for the ex-25, too. It turns the 40-150 into a very capable close up lens.

Hi everyone!

I've just had a quick look through my photos and found some I took with my cheap macro lens and my 14-42mm kit lens on my e-510.

The first is my OM 50mm f1.8 taken from about 2" away (hence inexcusably poor lighting)

http://e-group.uk.net/forum/picture.php?albumid=316&pictureid=1601

With an untouched pixel for pixel crop from the middle of the picture :-

And another attempt this time on a pepsi can, again from around 2"

http://e-group.uk.net/forum/picture.php?albumid=316&pictureid=1599

and again a crop from the middle of the picture :-

http://e-group.uk.net/forum/picture.php?albumid=316&pictureid=1598

In both the crops there are some signs of chromatic aberations, but to my eyes they are not too visible in the full size versions, especially when shown at the resolutions used on here (but as I said earlier, I'm a philistine!)

I would certainly have the EX-25 if I had the means, as well as a 50mm f2.0 Macro, but at the moment they are both well out of reach (at least until a lottery win:))

Cheers,

Ralph

Hi there Grissely!

I had a quick try with the +10 diopter macro lens on my 40-150mm this evening but found that it really needed to be very close to focus - around 2-4" away! At this distance with the lens set yo 150mm you got very high magnification, however the depth of field even at f11 was about 1mm! I'll post an image when i get a chance - I didn't have my tripod out this evening and getting a good image without moving backwards or forwards 1mm was tricky!

Cheers,

Ralph.

I have that very Sigma one and found it useful last year on my E-PL3 and 40-150mm

Taken with the above set up and very little cropping.
