The 40mm works well for outdoors shots:

The DA40 is essentially the M40 without aperture ring.
Just to clarify, it might have the same focal length and similar physical characteristics, but it's a different (superior) optical design, and also has about the fastest AF in the Pentax system.

Part of what I find attractive about 40mm on APS-C is that it helps one focus on just the heart of a scene, cutting out some of extraneous stuff. But not so much that it seems like much of a "telephoto".

Interesting thoughts on the 40 -

I second Marc's sentiments on the isolation factor of the DA 40 on digital. It does not feel tele, but it's certainly more selective than a "normal" like 35mm, or more, 28mm.

It allows for a more selective composition, which can enhance your photography. IQ is pretty much perfect and AF speed means you will never miss a shot.

To add to Marc's comments, the layout and formula are similar but the elements were re-designed for the DA and the rear element of the DA 40 has Ghostless Coating.

M 40/2.8


The re-designed elements of the DA 40/2.8



Compliments of Dimitrov.

Thanks for the clarification, guys. My point was that the 40 (whether M or DA) is by no means a tele design, yet on APS-C cameras it fills the role of what are called "short teles" on FF. So it's rather like using a Helios-44 on a Spotty, but twice as slow (for DOF equivalence). Oops, did I just open another can of worms? Nice, juicy worms...

I was just out with the kit using it at 40. It's a little tight for a "normal", but it's certainly not tele. I suppose it's at 50mm that things begin to feel tele.

I agree with you there. Plus, I bet that when the development of the DA 40 started, Pentax was working on the MZ-D.

Bite, bite.

I'm still stuck on the fact I can shoot through a chain link fence without interference.
Works really well on a micro 4/3 body too.
Would that be sacrilege?

I have done that. How can you control the aperture? It does pretty good wide open.

Courtesy of a fotodiox pk/m43 adapter (which was suggested courtesy of JohnmFlores). All of $30.
The stops aren't marked - its a slide on the adapter body over an internal screw that pokes out and activates the diaphram lever on the lens, but I found I can approximate F4.0 pretty well (compared with stop down aperture on the K-7), and as it is LV, can see the DOF in the monitor. Pretty cool, and a nice tele effect.
But sacrilege for sure.

Holy flip, I forgot about that feature. :BrownBag: Woo hoo. I had used the A 50/1.2 and FA 77 on there so much since I got the Fotodiox, I totally forgot about that feature.

DA 40mm

The DA 40 is AMAZING!!!!
I only have this and the kit lens but I have barely touched the 18-55 since I bought it!
Images are perfect perfect perfect, amazing sharpness, colours, no fringing.
A bit of vignetting at f2.8 but to be honest, I like it!
If the other Limiteds are this good, I think I might just buy all of them!
Some photos I have taken in the week I have had this lens:


Angel Up Above


White


Rainbow Bokeh


Choo Choo


Japanese Garden
I also found it perfect for panoramas! Thanks for viewing!

Nice pics.... but I have bad news for you, not only are the other limiteds as good, a few are even better....

From the limiteds I have I think the IQ pecking order goes DA21 < DA40 = DA15 < DA70 = FA77 < FA31.
