Hi, Pentaxians

In combination with my K-7 kit (18-55WR) +DA* 200mm, I'm planning to use the: DA 15mm, 40mm, 70mm and 35mm(macro) limited edition. (40mm I already have)

Simply because they have some kind of “jewellery quality” very compact & discrete!

I just love them, contrast, colour & IQ are superb, but one FL is missing though, at least for me and my needs!!
So in the future, I'm hoping for a "super wide-angle" DA 10mm Limited!

My question is actually, is it possible to make it, that compact and at such a high quality standard, because mostly SPW's are very big and bulky?
But with Pentax you (we) never know. :D

Best regards
Stone

Never thought of them as jewelry, but that is a fitting name for them :) Esquisite feeling lenses, not totally necessary, but very nice and pleasant to look at the results.

It is possible. I imagine a 10mm f/5.6 could be fairly small still, but f/5.6 is getting fairly small aperture and people might not like that. At f/4, it would be bigger, maybe the size of a DA 14mm f/2.8? But probably a bit smaller than a Sigma 10-20mm f/4-5.6.

This would be out of the "compact" range. I would just as soon see them forgo a compact 10mm, and make either a DA* 10mm f/2.8, or the Tokina 11-16mm f/2.8 in Pentax mount as a DA* lens to go along with the 16-50, 50-135 or 60-250). The zoom would likely be more pratical, and the quality of that zoom is very high.

I would go along with the other two posters. A 10mm prime would be tough to make pancake size and so should be a DA* instead.

I would like to see a line up like this to go with what we have:

DA*: 10mm f2.8, 18mm f2.8, 28mm f1.4, 85 or 90mm f1.8, and a 150mm macro f2.0, all sealed all TOP quality optically.

DA Limited as presently constituted but with the addition of the "Muffin" lens as it was dubbed a while ago: 120-135mm f3.5 as small as possible and with 49mm filter ring. (Similar to the M-135 f3.5)

But that is just me.

It could probably be made smaller if it was a fisheye lens, the analogue of the 17mm fisheye from film days. That would be interesting and could probably be de-fished in the computer.Perhaps Pentax could include the software with the lens.

I agree. Nikon's 10.5mm 2.8 DX Fish is very small. I am sure Pentax could do even smaller.

Btw, is it true that the lens cap of the DA 35mm macro doesn’t fit properly and has a tendency to come off?

I don't think it's optically possible to make a UWA pancake. The whole idea of the pancake lens is to have a very simple design, and that only works within certain bounds of FOV. As someone already stated, a fisheye version would be entirely doable, but to correct for perspective one needs a lot of lens elements, hence the size of, for instance, the 14mm lens.

T'was actually a man reason why I chose the 10-17mm instead of a conventional lens: I don't mind the fisheye effect, and it fits nicely into pockets etc...

It fits properly, but there is very little contact area for it to grip onto the lens collar with . So just catching the camera against your coat pocket, say, can flip it loose.

A couple of months ago this happened to me in the middle of a beechwood. Dry leaves all over the ground, so it should have been hopeless. But it's an area I know well, so when I realised a few minutes later, I could exactly retrace my steps (helped by referring to the pictures I had taken). Found it :-)

I also have a DA21 and DA70 with the exact same design of velvet lined cap, but in those cases it is much more secure, because there is more projection of the lens hood (always fitted) allowing a far deeper cap.

It sure does on my DA 35 and it's really annoying. It should be a tighter fit.

Would it be possible to attach a normal 49mm “snap-lens cap” on the 35mm, or isn’t that impossible due to the special design of the lens?
It want hold me back, buying one, though. :D

Wow, lucky man you are.
Would a normal 49mm Pentax cap ift?

Exactly, when putting the: 15mm and 14mm side by side, they did a great job on the 15mm, in terms of compactness.
Of course a 10mm (non fish-eye) would be another ballgame, though.
Maybe I’ll better say the rosary, than hoping or wishing 4it. :D

Of course, but in very densely populated places, like markets or shopping malls, it might come in handy, though!
A lost "original" one, would be worse and very expensive, I’ll guess! :|
