Best lens for macro electronic components

<< < (3/11) > >>

Zucca:
Similar setup here Pat...
Manfrotto are a must!

I used the Canon EF 100mm f/2.8L IS macro a lot but I am looking for a x2, just because sometime I need to go beyond the 1:1 barrier.
Moreover the Laowa 100mm f/2.8 2X is much cheaper. And since I am on a tripod anyway for macro I do not need too much IS.

Cubdriver:
If you want crazy close, the MP-E 65mm goes 1:1 to 5:1.  That one is definitely a challenge to use, and a focus rail is a necessity









Above displays taken with the 100mm for size reference:

Here's another site for more exotic close up lenses.

Best,

Zucca:
Those pics are stellar!
2:1 is just for 1%, 99% I will stay 1:1.

No need to go 5:1, but you are temping me!

A superb macro lens that was used in 9600DPI dia scanners:

A comment on http://extreme-macro.co.uk/extreme-macro-closeup-lenses/ said interestingly:

A far cheaper solution is to get hold of a damaged pair of 10x50 binoculars and use its objective lens, which typically is c. 51 mm diameter and c. 200mm focal length (+5D)
Glue it into an appropriate 52mm step-up or step-down ring (e.g. Kood) but with the original INNER face that was towards the eyepiece NOW facing outwards.
It should be that way round because that was the correction for which the objective lens was originally computed.
You'll find the image quality and flatness off field are very close to those of the original prime lens.
You can make a "hood" by glueing a 20 mm wide ring of thin cardboard around the exposed part of the objective and painting the inside black.


And a lot of information on achromatic add-on macro lenses:
