I picked up mine this morning. Unfortunately my schedule is such that it's going to sit on the shelf until Sunday.

My HD DFA Macro arived today.
I still have the old one so i can take pictures for comparison.
Serial No. 0000014 :-)

So, here are the 2 images. It was a setup, animal dead (found it dead in the forest, 3 month ago, i don´t kill animals for pictures), camera on tripod, same settings, flash. I only changed the lens.
It´s nearly out of cam.

K_1 1998 is the smc
K_1 1999 is the hd

The upper one is the old one, undernearth the new.
But in the Exifs you see, Pentax don´t change the Name. The new one calls also smc Pentax...

So, the question. Do i see differences?
When you use it for macro, a little bit. Sharpness: maybe a little little little bit. Imaging performance: yes, the insect is more colorfull, more green and yellow. Chromatic aberration: there is an example, a few pages before.
I think the best thing about the new lens is, that it no longer has the chromatic aberrations. The rest is relatively the same. But I love the new lens and am looking forward to the next insect season.

New one definitely have more vivid colour rendition. Thanks for posting those

As for naming the lens in EXIF, probably new firmware will have them sorted to reflect correct model name in EXIF

Mine is on the way. Silver of course. Hopefully it will hit the front porch by Monday.

Lens names are interpreted by the software *reading* the exif. So the software has to be updated after a new lens is released. I can't remember if the hd fa 35 ever got detected properly. It was/is the smc fa 35 in exif.

Mine showed up yesterday. Unfortunately, it was defective and would not lock focus while shooting through the viewfinder on either my K1-II or K3-III. It wasn't all that securely packaged, so maybe it was damaged in transit. I sent it back immediately and I'm now waiting for a replacement. I hope they package the replacement much more securely.

Fast and accurate in LiveView, but just racked back and forth and then stopped completely unfocused while using the Viewfinder. Does anybody have ideas why the contrast detection autofocus would work fine but the phase detection autofocus would fail completely?

I have no idea if there's any connection, but I have the exact same problem on a DFA 50mm macro that works fine on a K-3 but shows that hunting/unable to lock behaviour on the K-3iii. Mine is old, tried cleaning the contacts but to no avail. And, if it works on the K-3 I'm not sure poor contact can be a problem...
So far was unable to solve the issue.

at the top of the label - the purple fringing looks really bad...




Yet on a subject that I would have expected to see a problem, it is excellent....





Joking aside - the new HD Pentax‐D FA Macro 100mm f/2.8 ED AW certainly does handle fringing better than the older version.

[thibs]

LOL Good one

[VictorDA]

Poor testing conditions. I'm sure if you try again with a Chardonnay or Sauvignon you won't have any issues

I can't believe you wasted that much wine.

Yeah, the CDAF isn't looking for alignments, it's looking for high contrast, which will occur even in a defective lens.

But misaligned elements mean that even if you used it permanently in Live View, the images will still suffer in sharpness compared to everyone else's copy.

I haven't tried it on the K-3 Mark III yet, but my copy worked pretty well through the viewfinder with my skittish granddaughter today.



....and my slightly less skittish daughter Yes, if you look hard, there is a bit of purple fringing around the extremely contrasty rim of her glass, but with the SMC version it would have been visible from the moon!

A good friend also had purple fringing on a bottle of port showing with his new 100 macro and tried bottles of both Chardonnay and Cabernet Sauvignon. He now reports a complete inability to focus, a raging headache and terrible nausea and has called in sick.

Thinking about getting this lens. I have researched, and don't see this listed anywhere-is the lens hood reversible and mounted onto the lens for storage? I would assume so, as the last version did this.

Just want to make sure.

TIA!!
