K1 close ups with DA 35mm 2.4 / FF with ext-tube
10

This gets about a mag of 1:0.6

Some time ago I removed the lens from my SIGMA AF Tele Converter X1.4 resulting in an extension tube of ~17mm.

The PENTAX DA 35mm f/2.4 AL is known to be usable on FF. This is also true with this extension tube. Giving a not to close working distance and a ratio of ~ 1:0.6 for FF.

All images are untouched OOC-JPGs hand held with AF using the OVF.

I think Bokeh is very good.

Hexagons can be seen, but they are without onion rings - cool.

The following is without ext tube - about as close as possible:

and finally for comparison with ext-tube:

Nice set of images and good write up.  That 17mm tube really makes a difference!

Thanks Tom, Spyros, JCDoss and Dean

for your appreciation.

I was surprised by the quality delivered by this consumer lens in close distances. 

This lens seems to have the same optical formula as the (older) FA 35mm F2 AL (see PENTAXforums). It is a wolf in sheepskin.

Re: K1 close ups with DA 35mm 2.4 / FF with ext-tube

Hello Kerusker,

That are very nice pictures with this combination. It's also nice to see what very good resolution this lens has, so that the resolution with a extension tube combination is still very nice....and it's bokeh also.

beat regards. KPM2

Danke KPM2,

leider kommen keine Eichhörnchen um mit mir zu frühstücken 

I still have the Pentax A 28mm 2.8 and an Olympus IS/L A-Live Size Macro (f=130cm).

Just for comparison:

The M and A version have the same optics (I guess).

What's the focal length of the Pentax S40?

Thank you for this very nice pictures with your close up lens and your A 28mm. Very nice and tender transition into the out of focus area with this combination.

I don't know the focal length of the S40. It was made for the SMC 50mm lens, but I use it now with my 28mm. I only know the magnification I can get with the 28mm lens and it's ca. 1:5

best regards  KPM2

Re: K1 close ups with 'Bokina' 90mm for comparison

Today I received The 'Bokina II' (Tokina AT-X Macro 90mm 2.5) from Japan.

I may have to better fine adjust focus (indicator). On screen of the OVF focus pops in (on close distances). It's an A-lens so no AF (except catch in).

Hand hold shooting at closest distance (0.5 magn.) isn't easy.

So just for a rough comparison (unprofessional) three shots:

I have to learn how to make the best use of the Bokina.

Anyhow, I'm impressed by the DA 35mm 2.4 with AF-close-up ring.
