Not quite as in focus as I desired, but I didn't have much room to maneuver...

Been having crappy weather lately, and I couldn't come up with something creative to shoot inside (that I haven't already shot), so I decided to just do test shots with the 105mm f2 DC.

I've been trying to figure out the DC control. I took some shots at f2, but (maybe a poor choice of subject), the DoF differences with different settings, didn't seem to change much. So, I shot at f4 and then f5.6. Decided to use the latter f-stop for this test.

My focus is on the pair of brownish/green "leaves" in the upper center (about a third from the top, not the lower group of four that are almost centered). The read beads are in the back, the skinny leaves are closer, and the green leaves dead middle and lower right are the closest..

The first shot is with DC set to 5.6 REAR:

The one leave is in focus, but the one slightly behind is not. The other leaves that are closer, are also in focus or slightly out. The red rear beads are well out of focus.

On the second one, I had the DC set to the center mark (I guess like no defocus at all?):

A little less defocusing in the rear, from what I can tell. Seems like even more focus forward. The little plastic leaves on the right that are closer, are in focus).

The last one is with DC set to 5.6 FORWARD:

Now the closer of the two leaves is out of focus, as well as everything closer. The red beads in the back are in focus as well.

It seems like the focus range is wider, when DC set to FORWARD, than when set to REAR.

Maybe I should try this again, with a ruler instead...

Sorry about the boring shot.
Very nice Paul. Exactly the way I started with mine.

Very nice 👍
Good work with these. Hoping that the jet stream gets back to "normal" pretty soon!
Very pretty. Isn't it crazy that teens seem warm!! We have bad winters in Idaho, but I'm pretty sure you have it a lot worse. Beautiful photos.
Both of these are quite nice ... but the second one is really special!! Well done!!

Ken
I second what's been stated before: these look warm. Great mood, after all the very cold winter weeks. Enjoy the last warm snow, visually.
Thanks to all who responded to my photos. Your comments and votes are most warmly received!
I have been getting used to my z 70-200 2.8 and am truly impressed with the image quality especially when working wide open. Looking forward to spring when the woods start to bloom and my favorite subjects return to the warmth.

From today's dog walk. Almost like Spring here today. Far too soon, as we shall no doubt find out in the next few weeks.

f16 View. I could have done with f32. Or got further away from the tree.

Good demonstration on why to use a smaller aperture for landscape pictures. Nice job.

Nice landscape, lots of sheep. Any predators that they need to worry about?

There's no thinner DoF with that lens, at this distance, and that angle. ;)

Don't ask. Don't look to carefully. I'll leave the victims out of DoF. Looks like a terrible riding accident... :D (Mayla's stuff)
