So the 2nd ruler test at http://theearlybirder.com/aperture%20200mm%202/index.htm#19 was not a good measure either, and I should try a butterfly wing? And with the Nikon lens F11 would be equivalent to F22 and may be fairly optimal? Perhaps F18 or f20 reading would be pretty good then. And then don'...

Rik, I always appreciate your input. The main reason I put the ruler tests up was because I was not getting good results and Chris thought my lens was broken. I thought the results of these tests could indicate if it wasn't functioning properly at the different apertures. The second series with the ...

I redid the test because I thought that I may not have done it at x1. for some reason CS6 does not show distance. Attached is an uncropped one. CS6 does not produce the type of web gallery that I want so I went to CS5, where I make my galleries, and behold there is the subject distance as .5m. And i...

I just drew a rectangle around the series in Camera RAw and cropped that way. After spending most of the day, trying out ControlmyNikon, I decided I wanted to try out the 4x objective I had bought in December. I did the head of this galerita, with 115 steps of .015 at F11 with a dust mask over the f...

I didn't see any point in leaving in a lot that was never close to in-focus, so I cropped them all in CS6 camera raw to have a larger final image of the more relevant area.

aperture comparison

I set up a leaning ruler and photographed it with the 200mm macro at all the aperture., to see if you think there is something wrong with the lens. Rather than clutter up here, I have link. http://theearlybirder.com/aperture%20200mm/index.htm None of the links on that page go anywhere as it is in a ...

I looked up that ControlmyNikon and it looks great. The videos are very useful. The stacking one makes it seem like I didn't need to get Stackshot rail though.

Sorry for the confusion. I was confused because I didn't notice my images were resorted when the software renamed the stacks. Top image was 60mm at f11. I trusted autofocus to get the top in focus. In the earlier series I had used manual to start and since they were determined to be unsharp I though...

My first 3 comparison images were with Zerene, Helicon and Photoshop. At first I was not able to get a result with CombineZ but later succeeded and posted the same stack with 4 different methods. All 7 seemed to have rather similar results to my untrained eye, and those were with F32, I think. When ...

Here are 4 different processing of the first stack I had done before with the 5T. That was with the F32 and 1/3", same stack as previously posted with different processing softwares. http://www.photomacrography.net/forum/userpix/3832_rectangle_NewOut99994_Pyramid_Maximum_Contrast101a_1.jpg http://ww...

On the 200 macro was a 6T closeup lens on this beetle. On the previous Bombardier was the 5T, both on the awful shots and the previous better ones.

The aperture was from the readout, not the lens barrel.

Perhaps the subject position is not stable enough.

I tried the 2nd beetle again today, with f11, 1" ISO 64. I took some text focus shots, and then I found a 1/2" layer of styrofoam that I wrapped around a translucent plastic container that Chinese soup came in. This seemed to get rid of most of the reflections. I used steps of .067mm. I thought the ...

So do you use 2 series, to allow for the pin and merge them? Thanks for the followup.

I have a 60mm macro. I forgot that I don't need to use the 200mm, since I'm not using the 4x microscope objective I got for it.
