Close up filter on Macro Lens

[smtan24]

Just curious what happens if you put a close up lens on a macro lens. Would that mean you can focus even closer to the object of intrest.

well hopefully... i ordered a close up filter from the MO done by hptay for my sigma 105mm macro =D

Thinking of purchasing a Tamron Lenses: SP AF90MM F/2.8 Di and using my +4 close up filter on it. Since the minimum focus distance is 30cm with the close what would the new focus distance be.

I have a feeling that close up filter will magnify with longer focal length, so a 300mm lens + close up filter will magnify a lot, but the depth of view is really so small.

technically it lets you go closer... then when closer, it will look bigger... same like a extension tube

i have a +4 for my 70-300mm sigma (with macro between 200 - 300). was advised by the lady at seng cheong (i think - hoya distributor) NOT to buy it but did anyway. it works fine, i.e. prob can call it super-duper macro, but then you'll have to get REALLY close to your subject. not recommended...

The minimum focus distance of the SP90mm is 11~12cm izzit??

True macro lens is 1:1. Magnifying it further by using close up diopter will make it greater than 1:1. E.g. 2:1, 3:1 and so on. Also after attaching a close up diopter on a SP90mm you have a minumum focusing distance shorter than the original liao.

Question is, do you wanna shoot a hornet that close?? :bigeyes:

my exact sentiments.. i tried it with my 300mm zoom and ended up so close (without realising it) to the iguana whose eye i was trying to shoot, that our faces nearly touched... :sweat: never again! :bsmilie: :bsmilie:

I did some test on the extension tubes as well as the macro lens.. here is the result

Although the extension tube with 50mm f1.4 lens is sharp in the center (taken at f11 for both), the side suffers a lot for the 50mm f1.4 (50mm f1.4 +12+20+36 ext tubes)

Look at the 100mm f2.8 D.. it is nice and sharp.

Both taken handheld using 5600HS flash.

Actually for Tamron 90mm, if you are using manual focus, you can get much closer than 30cm. Just extend the lens all the way out and you can get as close as 1cm, I think. Focusing is done by moving the whole camera. The DOF is very shallow so using tripod with macro slider is recommended.

Of course, it will not be practical for bug/ insect photography. So getting 180mm would be better. Of course, the price is much more expensive. Or cheaper option is using reverse 50mm method.

Anybody has auto focus problem with the Tamaron 90mm F2.8. My lens can't focus properly. I'll have to press the button again to try to auto focus than it would work. I'm using a Dynax 5D.

OT a bit... was considering the reverse 50mm method..but since Minolta lens has no aperture ring... how do we select the aperture size when we reverse-mount the 50mm? Thanx in advance! =)

You buy an old minolta rokkor 50mm f1.7 or 50mm f1.4. You can set the aperture manually.

Or if you already have a AF 50mm, then just use a piece of paper to stuck it on the aperture control lever at the back of the lens.

OR... he...he... make a hole in the middle of the rear cap (can only work with Minolta or KM rear cap). The rear cap opens the aperture to the widest when it is screwed to the lens. It also works as the lens hood:thumbsup: Do this only when you have extra lens cap!!

 

[rOnGrEn]

:thumbsup: :thumbsup: both are good ideas to work around things...

rear lens cap can choose the degree u want to open the aperture too.. haha.. thanx for the input!!
