So I was a bit bored today and got to thinking...

By now, just about anyone who's been on these forums for more than 3 months have heard or seen the terms "pixie dust" and "3d pop". Usually these terms are applied to fairly expensive hunks of glass (expensive is subjective, I know... but think expensive for people working low-average paying jobs for this basis). Which brings me about to the thought that popped up while I was playing with my F 35-80 during my lunch break. What cheap, sub-$100 usd used price range lenses might these terms be applicable towards? I'm certain there are a few out there in the wild... maybe sleeper gems, possibly. What, if any lenses do you think would qualify for this (the plastic fantastic is outside the price range for this topic)?

Seeing as the DA50 is now selling for stupidly low prices new (it seems to break new records every week), I think it definitely enters into the argument.

I thought 3D pop only happened with certain lenses, but I've seen the DA50 and a couple of other lenses do it at around f/3.5, and I think the secret is to have the subject sufficiently isolated from anything in the background that you can catch the subject in a narrow band of sharp DOF and have no significant sharpness left by the time the background comes into play.

This is not to say that there aren't lenses whose formulae are (for whatever reason) better at doing it consistently; there certainly are. But from time to time I think you will see the effect with any lens if conditions are right.

If you don't mind using M42 screw mount, I find (at least my copy in any event) of the Pentacon / Meyer-Optik Gorlitz Lydith 30mm f3.5 Lens is such a lens. It seems to have the same 3D pop as my FA limiteds

This is a highly subjective topic because I think a lot of the "pop" has to do with the shooting conditions. That's not to say I don't believe in it...because I do. I just think that for 99.9% of the things that we shoot, any Pentax lens is more than up to the task.

I've had fantastic shots with the da50 and the da35 and the pancake 40.

but, are all of these lenses being suggested under the price of $100 USD used (in workable condition)? I don't recall seeing a used pancake 40 for less than $115 lately (in good or better cond.). I'll take people's word on the da50 though....

I Love that 40 XS so much I use it when I shouldn't, just cause I can.

I just to have happened to have been out with my $49 FA 35-80 today. What a coink-ee-dink.

Put me in the 40xs camp ($92 new), as well. Probably lacking pixie dust, but I do see more 3D realism than I get with the DA 50.

For me, a sub-$100 lens that checks the phenomenal IQ box is asking a little much. On a good day, the DA 50 can overcome its focusing deficiencies, unusual rendering, and in the right conditions produce a hugely sharp image that can be stunning. The 40xs just does everything so well, in a range of f-stops, consistently yielding images that are evocative - but possibly not quite stunning. At under $100, I'm a fan of consistently evocative more so than occasionally stunning.

I love the 40mm XS as well, it was the first prime I bought for my K-5. I actually have to force myself to swap lenses because this lens can stay on my camera all day, every day, for weeks at a time. It has not disappointed me in any conditions I've used it in.

The bizarre cheapie favorite that's been mentioned around here before is the Quantaray 28-90mm f/3.5-5.6 1:2 macro. Fast to focus, really light, 8 aperture blades. Its macro is only at 90mm. I've heard no complaints from anyone about this one. Well, maybe some grousing about the plastic mount but images are always good and often exceptional. Here's one of my favorites from it, with K-01 and a hose on a sunny day



This lens has a few variants, a 28-90 Q-ray not-macro and Sigma 28-80 1:2. All the 1:2 types I've tried have been really good, and often they appear for under $40 - even after the praise it gets! My latest copy is a silver 28-80, I paid $27 for it a few weeks back.

As you mention plastic fantastic I think that original lens who acquired this term qualify there as well - Cosina 100mm F3.5 Macro aka SMC FA Pentax 100mm 3.5 Macro or Vivitar.

This lens always amazes me how fast is with AF and accuracy. Sharpness is excellent as well (sharper than Sigma 105mm 2.8 EX DG Macro) and the 3D pop is there but as some people mention that before it needs to meet certain criteria in order to have that... I tried to find better lens in this focal length but still until know every single lens I tried is not sharper nor as fast in terms of AF and accuracy. This is very strange and might be limited to some copies but I do not think so.

Here is recent example of slight 3D with 100mm 3.5 macro at 5.6
