Im counting down the months till i am finally able to play with a k-1, but was curious on how the da 16-85 will work on the k-1.

Any one try the k-1 with this lens?

Is this lens strictly a crop lens, or at which focal point will it work on full frame?



Any info will be great. Thank you in advance

It's a crop lens, and I doubt it will perform well on the K-1.

Imagine a circle touching the middle-left and middle-right of the sensor. (The circle goes beyond the middle-top and middle-bottom of the sensor).

That, roughly, identifies the boundary of the image at all focal lengths. Beyond that appears black. The quality probably drops off near that circle.

It will work in Crop Mode on the K-1, of course. It should also be usable over a rectangle narrower but taller than the APS-C boundary. But mostly it would make sense to use it in Crop Mode.

A number of Pentax "crop lenses" are perfectly useable on FF, including the DA40, DA70, and even the DA 55-300. So I'm not going to jump to conclusions about the 16-85. I too am very interested to actually see it's coverage.

I have a 16-85. It would be nice if it did cover a majority of the K-1 FF mode image gathering. It is nice that it can be used in the aps-c mode.

I'm looking for someone who has tried the lens on the camera, and can give an idea what they have found. The da* 55 is a crop lens but from what everyone is saying, it's usable for a ff lens.

I understand that you want some real results, it looks like for now we will have to wait. But I will just note that the chance of a DA prime working on FF is much larger than that of a DA zoom working, because many of the primes are based on FF designs. E.g. the DA* 200 f/2.8 and DA* 300 f/4 work flawlessly, because they are essentially FA lenses in a new coat. The same may be true for the DA* 55 f/1.4. But to my knowledge there is no DA zoom that is based on a FF design.

It will work in crop mode, just be prepared to throw away 21 Mp or so.


Almost no DA zoom or DA wide angle prime will give the coverage you want in FF mode.


The new D FA 28-105 is an analogue of your DA 16-85 on APS-C.

Its understandable. Im hoping that a good portion will function though between the 30-85 range with minimal vignetting. Its one of my favorite lenses i like to use.

Do you have access to an old film body? Just looking through the viewfinder should give you a rough idea.
Personally, I think it is very unlikely to be a useful lens on full frame.

[Adam]

Grab the 28-105mm. It'll become your new favorite

There will be an article on the homepage comparing all DA lenses kn the K-1, so stay tuned for that.

Unfortunately not with a k mount, only film bodies i own are canon and olympus.

The 28-105 is only about 19mm APS-C equivalent at the wide end. I would really miss the 16 from the 16-85 (not to mention the DA 15 Ltd).

To me, a moderately priced reasonably compact wide angle (equivalent to 15 or 16mm on APS-C) is the big gap in the current Pentax FF arsenal. The D FA 15-30 is not a carry-everywhere lens.

If I remember tomorrow, I'll try the 16~85 on K1 in FF mode and post a couple images here.

Oh nice, ill be looking forward to the article.

Its sooo tempting to start changing completely over to full frame. Im trying to resist the urge, haha. Somehow i keep on hearing the line "resistance is futile" from a movie i watched the other day.
