My DA Limiteds on the K1

I have finally had a chance to try out my beloved SMC DA Limiteds (15, 40, and 70) on the K1. Although they are all officially crop lenses, the latter two at least have shown signs of being able to migrate to FF. So here are my findings, with representative images.
  • DA 70 Limited definitely FF compatible (1/160, f/8, ISO100)


  • DA 40 Limited little vignetting but a bit muddy in the extreme corners (fine on the edges); useable-to-good (1/40, f/11, ISO100)


  • DA 15 Limited forget it (1/30, f/4, ISO1250)


The DA70 and DA40 were with hoods; the DA15 without. Using the hood on the DA15 vignettes much more.

Nice results on the DA40 and DA70, Paul! Did you try wider apertures, by any chance?

Yes. There was no noticeable vignetting from either lens even wide open!

Fantastic. Those will be nice focal lengths on FF

Nice. A good central composition with the DA40 should draw the viewer's eye away from any dodgy areas. I haven't got extensive experience with it on film, but nothing I've ever photographed with it seemed to show any particular problems.

Slightly OT, have you got and tried the DA50/1.8? It worked acceptably for me on film. I would use it on my newer film bodies, but on everything except the Super Program I am in auto-only mode and can't really make best use of it - and the same applies to the DA Limiteds, of course.

DA70 vignette

Hi Paul,

Lovely detail in the helicopter there mate. I've always had a sweet spot for the DA70.

It's interesting that you didn't get any vignetting on the DA70 wide open as I did find it on my SMC version of that lens. Nothing bad of course and easy to fix. I've only been out once with the K-1/DA70 and didn't shoot the lens stopped down too far. From that one trip I found vignetting present down to f5.6.

f2.4


f5.6

Interesting.

You wonder if perhaps they changed things between the SMC and the HD variants in a way that made a difference.

Those with access to a K-1 and examples of both SMC and HD versions are invited to compare and comment...

My son has the DA 50 f/1.8. I just threw it on the K1 for a quick test. There is a little darkening in the corners, but this is largely cleaned up by applying lens correction in LR. Here's an uncorrected image (f/2.2). I'm afraid the lighting isn't completely even, but you get the idea.

It's worthwhile keeping in mind the possibility that even when there are some limitations in using some DA lenses on FF, the useable area may be larger than what one would obtain using CROP mode, so that cropping in PP would be the better option.

OK, at f/2.4 there is some minor corner darkening, but this is pretty well cleaned up by profile corrections in LR.

I don't mind the vignette personally, and as you say it can be sorted in post easily. The DA70 is a great lens and it's well worth using on the K-1, something I think we both agree on.

The DA 70 vignetting wide-open hardly seems noticeable.

Vignette seems part of the FF 'look'. Which is good, because I think folks will be hard-pressed to find ANY fast FF lens that doesn't vignette noticeably wide-open. Go through Lenstip.com and have a look at the vignetting tests for a few fast FF Nikon's, Sigma's and Canon's (eg Sigma 35 f1.4 if you want to see real FF vignetting), or look at a few long FF telephoto lenses.

Hmm... I only took a snapshot or two, but I'm not happy with my SMC DA 70mm border performance on FF. I've put it on my "to replace" list.
