I am so sorry you don’t understand. Maybe you want to understand? Search for Equivalence, mentioned here many times. That approach tries to tell what is equivalent to what. Sensors count photons. ...

Me. I lost 4 years of Canon 5D photos from over 200 locations in Mexico. Had the main and backup both fail

Like when they discuss Santa. The dinner scene with her sister’s family you mention is very fitting, because the ones rejecting brutal honesty would be exactly like her sister and her husband at ...

How much do you have in mind. And did you try or even enjoy MF lenses? If you have a very specific use that requires AF, you need new lens. But if not, you have a universe of options at a trillion ...

I cannot give good advise, because I have more lenses than I use, and many on the same train of thoughts and research. I started thinking I am not collecting and use them. But it's a bit like ...

Double gauss is one of the most common structure, and I may have 40 lenses with that structure. As a very fast lens with very shallow DOF one would be right to be disappointed. But anyone seeing ...

I provided a definition. See Captain Fantastic and you get some sense of brutal honesty vs complete feel good fallacies and not even half truths. If your objection is about being pedantic, ...

Yes I don’t think they say better lens. The new version are fantastic. They just miss something, and what it is isn’t clear. Some iirc mention the less clinical look and overall resulting images. ...

Yes, and the 1.1 is really something like an f2 behind a speed booster. And based on images, it has so much spherical aberration that it seems more like a soft focus lens at f8.

Yes, the references you found which I didn’t know explain it much better. They are well corrected overall, but the spherical is pitched against other higher order aberrations in effect using one ...

When we see we see 2% of the scene, but what we see is very detailed. So the pic needs to be very detailed if it will try to capture a scene. I sit on row 3 in cinemas and I enjoy using peripheral ...

My 2003 Canon 5D is 12MP so it fills 4K. Sensors are  grids of square grids. When the scene also has patterns, this discrete nature of the sensor and the geometrical shapes in the scene, cause ...

Yes, I think it's better for each one interested in the DOF to look at samples and make their own judgment. I think of the Mitakon almost as an "in lens" photo stacking solution and the ultimate ...

Look for the spherical aberration section and look at the DOF example produced in the ruler shot that compares 0.95 and f1.4. Notice how things never get blurry in the background. One can still ...

.I checked ebay out of curiosity, and seems like most holding to the lens aren't selling it. The only MMG to be found is listed at the bargain price of over $2000, and the cheapest AE over $1000. T ...

Besides the shading and many factors that are primarily the scene, there is also a contributing factor, depending on the scene, regarding length, smoothness and direction of the blur. Given a ...

What do you use for stacking? Great pictures, pretty amazing places.

What ways or apps other than that do you know or recommend to align multiple images, each of course will be a little off from each other. I could not find and app and all the astro apps are so ...

Really?

Anything BUT NOT a cheap good old manual lens. Because after the second, you may find yourself buying an entire cabinet.
