Beyond 1:1 macro

[Dogfish_magnet]

I have started to find small insects and spiders that still appear very small even when using 1:1 on my sigma 105 lens, if i were to use a 1.4x converter would i get 1.4:1?.

Anybody tried a ranox on a macro lens and if so what were the results like ?

Thanks
Paul.

Paul,

A t/c will work but you'd be better off buying a set of extension tubes. They'll reduce the minimum focus distance and allow you to get greater magnification without any perceived loss og sharpness....the t/c will undoubtably nobble the IQ a little bit and is far more expensive.

:thinking: My next door neighbour has a set of extension tubes.....i feel a plan coming together.

Thanks Bob.

Paul,

A full set of Kenko tubes will give you approximately double the native magnification (1:1) when you are at the minimum focus distance.

50mm f1.4 held on to the front of a sigma 150mm macro with pvc electrical tape (lenses are face to face so back of 50mm to subject)...

RObert those are AMAZING! Is it possible we can get a few more details, possibly a photo of your setup and how you attatched the 50mm in front of the sigma?
Thanks!

A sigma 1.4x tc will not work on a sigma 105 due to the rear element. Im not sure if other converters will work.

Extension tubes might be a better bet.

Looking at that shot Stan, it seems you've got what's needed now.
