More Test of DA* 16-50 and comparison

The only thing that I think I see is that the DA* 16-50 is a bit soft at f/2.8. At f/4 and up, it seems to be OK.

In comparison, the 16-50 seems to be much just slightly sharper than the 16-45.

Thats been pretty much what I've seen personally with mine compared with my friends 16-45. The 2.8 is a bit soft, but it doesn't take much PP'ing to bring it up to a high average.

Ed,

It looks like you got at least a decent copy of the DA* 16-50, as the * images look as good or better than the comparable 16-45 images. My guess is that the sensor wasn't quite parallel to the wrapping paper on your first tests. Hope that helps you decide.

Here are more test shots from the DA* 16-50.

The only thing that I think I see is that the DA8 16-50 is quite soft at f/2.8. At f/4 and up, it seem to be OK.

In comparison, the 16-50 seems to be much just slightly sharper than the 16-45.

I'll be quite curious what the rest of you think.

Ed
Your results with the 16-50 seem quite similar to mine. I do find that focusing the brute at f/2.8 is really, really difficult, the dof is so slight. Here is a corner of a shot of a local news story on my Flickr site, 100%. I cannot complain about this at all. The full shot is in the same place, almost.

Your test results indicate that you have a very acceptable copy of the DA* 16-50. I'll have to run this test on my copy.

What surprises me though is the fact that there isn't a greater difference between the two. While the 16-50 does appear to be somewhat sharper, and has higher contrast, I was expecting it to be much better than the 16-45.

I guess if having SDM and f/2.8 are an absolute must, the 16-50 is the way to go. Otherwise, stick with the 16-45 IMO.

Interesting that the TS who also started another thread on the DA* 16-50 https://www.pentaxforums.com/forums/pentax-slr-lens-discussion/18402-da-16-50...e-testing.html has decided to put it up for sale in the Marketplace. All the pictures have been removed as well. This after getting some favourable comments. Oh well...

I'm not exactly sure what "TS" means, but I'm pretty sure that it's not something very flattering.

I'm not exactly sure why you have a problem with the fact that I ran tests and then decided to sell the lens? I removed the pictures, even though I really don't need to explain to you why I did, to free up the bandwidth and to get them off of Photobucket.

Seems the foum owner didn't have an issue with the fact that I had two threads up.

However, it really doesn't matter as it's really none of your concern as to why I posted the tests or decided to sell the lens.

Have a nice day, Meatball.

TS = thread starter
Yeah it is your perogative to do what you like with it considering you created not one but several threads inquiring on the sharpness of the said lens. By all accounts the images you posted looked sharp and the comments favourable. So pardon me for wondering.
