This lens looks vey similar to its bigger brother Tamron 75mm f/3.9 which i posed some photos earlier. Again, it is very sharp even wide open. Iam loving it. These shoots were taken by Q7.

Actually I found focus peaking cannot achieve my desired outcomes when focusing. When you enlarge it x4, what you see in the screen is what you get. Yes, I did pixel peel it "when I did the focusing"! :) :)

I used LCD plus enlarging mode, but not focus peaking.

Yes, totally agree! But it's f/3.9, not a large aperture lens. Why?

Thanks!

Perhaps it's the long focal length (75mm X 4.6 crop factor) that made the bokeh looks so nice. :):)

I thought that only those large aperture cine lenses such as Cosmicar 75mm f1.9 can produce nice sharp image. I have never imagined that a f3.9 can produce high resolution pictures. It's a new found to in my hunt for cine lenses.

A very small c-mount lens with high resolution. I am impressed by its performance on such a small sensor of Q7. What do you think?

Upload a few more images (center crops) to show the resolution of this lens. DA*60-250 is wort the investment, particularly when it can be modified to cover FF. :D:D

Removing the ring actually means removing the baffle tube altogether. The ring restricting the image circle is an integral part of the tube. I took out the tube, filed away the ring and then fixed the tube back to the lens.

Thanks for the encouragement. Could not wait to learn more from this Forum. : )

Hi Everyone,
I am Ferrick, a new comer here. Recently I bought a K1 but found the 60-250mm couldn't cover the K1's sensor. I followed a thread here in this Forum and removed the baffle. The 60-250 is now a FF lens. See the results in the attached photos. Enjoy!
