15/4 limited smc and HD version comparison

Hi all, I would like to post this comparison aimed at showing the differencies between the "starburst" effect and bokeh of the DA 15/4 limited lenses in smc and HD version. These are screenshots from LR 3.6 and shots were taken in a quick succession.
Personally, I prefer the HD version for its clarity, reduced starburst and lower price
Thanks for comments!

My thought exactly.

That said, I wouldn't really care which one I owned as long as I had one of them. And I do, and see no reason to replace my smc anytime soon.

Thanks for the comparison, stanic!

Interesting.....I had presumed I would prefer the older model, but the bokeh is a surprise. Thanks for sharing.

Nice comparison. Just got the HD model after not finding a smc used for a good price. Have not had a chance to use it yet but based on your shots I think i prefer it to the old version.

I think in the same way, but can not finde a used one in Europe (for a reasonable price...)

That's why I bought mine new. For a rather unreasonable price. But I'm still glad I did

That is an amazing difference. Just to be sure I understand - the HD version changes were limited to the coating correct? They didn't change anything else did they?

also the aperture blades were rounded which apparently has had a big impact

OK - that makes sense. I wondered why such a profound change in the star patterns.
Thank you.

My votes would be, from top to bottom, SMC, HD, SMC, Tie, HD. Each has it's merits and the strength of the
star effect can elevate, (image 1 & 3), or detract, (image 2).

I'm amazed at the difference in clarity, however. I don't recall seeing such a profound difference in other
comparisons, (certainly not in the comparison made by PF a few months back), and can't help wonder
if sample error or some other effect is at play. The SMC version of image 4 in particular seems to show
noticeable motion blur in the upper central branch.

Fine lenses, both, and perhaps different enough to warrant owning both.

you are correct about the motion blur there, it was a windy night
however, my 15/4 smc has had a bit of bumpy life with me which shows (been to repair twice)
since I am not much of an artist, more of a pixel peeper , I am really happy with the HD version, to me it creates images that are more true to life than smc, which can be very well seen on the image nr. 4 - the tree branches are in reality not covered with little starbursts
thanks for comments everybody!
