If you attached the tripod to the body of the camera and could remove the back of the camera, then you could replace the back of the camera with a screen that you could use to compose. A 4x6 piece ...

Could also be the lens diameter not filter thread. Some lenses are roughly the same as their filter thread, but others are quite a bit wider.

I used the reference without understanding the entire science behind it. I would like to know more. There were instances of both near and far field diffraction patterns in the paper, so that makes ...

here is a little information on diffraction from different aperture shapes. Diffraction Patterns behind Different Apertures It is interesting to know the science behind the optics, but it rarely ...

By amount of diffraction I was referring to the amount of blur caused by diffraction, I was just not specific enough in my wording. Diffraction is not a number but rather a diffraction pattern.

There are different amounts of diffraction for different shapes.  a circle will have the least.  any change from a circle will have more.  Sun stars are a diffraction spike, so better sun stars ...

It is available to rent at this website https://www.lensrentals.com/rent/c-4-precision-optics-4.9mm-f3.5-hyper-fisheye-for-sony-e If you want to know a little more about Roger Cicala, the person ...

There are some large craters with central peaks.

35mm equivalent would be a 13mm lens, not including the senor or phone case. The phone is only 9.5mm thick. The camera bump would be very large for that lens. I would not mind a large camera bump,...

There is quite a bit of data on the lens rentals blog. here is one article about variation.

I second the rental suggestion. Especially if you are going to go full frame.  I just replaced my Panasonic G7 with an A7c. The camera is a little bigger, but the lenses are so much bigger than I ...

The lenses change some with temperature, but the changes that make the most difference are in the barrel. If it is metal there will be some change. If it is plastic there will be more change. They...

There are nets behind home plate. You can see the net in the background of the image at the top of the page. From the video, it looks like this was a remotely operated camera in front of the net.

I am not well versed in semiconductor design, but what interceptor121 has described seems to make a little sense to me.  I would assume some of the issues that he is raising is why larger sensors ...

I personally have changed the IR blocking filter out for a IR pass filter. It is not bonded to the sensor. Edit: DIY instruction for replacement. https://www.lifepixel.com/tutorials/infrared-diy-tu ...

I would imagine it is much cheaper to replace the sensor cover glass than the shutter if either is damaged.

If something mechanical was going to be removed, i would rather it be the shutter than the IBIS, as long  as I could get a fast enough electronic shutter. The A1 sounds like it's electronic ...

You referenced Wikipedia, but then chose to ignore the full description of depth of field. The depth of field is a property of the camera not of the photo.  So if a photo is taken that is blurry, ...

@Mariano Pacifico
The shipments Rodger was talking about were from his rental house to his customers, not new boxes from a retailer. I am not saying that it couldn't crack when shipped new, but...

Lens elements are made from annealed glass not tempered glass.
