Sigma 17-70 f2.8-4.5 Macro lens ( 1:2 ) with +4 close up filter

Sigma 17-70mm F2.8-4.5 DC Macro Lens Reviews - Sigma Lenses - Pentax Lens Review Database This one ....

Now the pictures are + a (+4) close up filter ...

I wanted to see if the +4 close up filter would make the lens more 1:1









Its a dark wet day , Camera is my K5 ...
Images have only been re sized , no PP ...

Last two images , the close up filter is actually pressed up against the bottom of each leaf ...
Yeah , looks like the lens will focus to contact now
Also you can pull back a reasonable distance , sorry didnt see how much exactly , and auto focus is working fine ...

Just need some nice weather ..

To get a sense of scale I used a Canadian dollar :

This is about as close as you can get @ 17mm


And @ 70mm ( About 10mm here , I could get closer , but Im blocking the light )


Images were re sized only , no cropping no PP

Unfortunately this lens is already listed in the database index.

You should have put your images in this thread.

https://www.pentaxforums.com/forums/lens-sample-photo-archive/156496-sigma-17...o-samples.html

There is only one thread per lens for the index to work

Thanks
