Lens – Manual EF-M Lenses on Canon DSLR – Is it physically, without an adapter, possible?

No, it is not possible.

Canon DSLR bodies have a 44mm flange focal length. This is to make room for the mirror.

The EF-M mount has only a 18mm flange focal length. There is no mirror, so there is no need to make room for it.

The EF-M lens, if mounted on the body of the DSLR, would be too far from the sensor.

In the other direction, things are much better. A mirrorless body can take almost any DSLR lens with a suitable adapter. However, it may be limited to manual focus only.

Canon: will an adapter with an EMF AF Confirm chip work with my vintage lens?

Yes. The EMF chip, when properly positioned and glued to an adapter ring, will perform auto focus confirmation and communicate EXIF ​​lens information (focal length, maximum aperture, and even the aperture setting used)Yes follow the right steps while shooting) on ​​a Canon EOS digital body (I've used them on an XT, 50D, and 5DMkII). The adapter ring and the lens to which it is connected do not really affect this function. The quality / fit of the adapter ring, however, is independent of the chip. The chip is sold separately from the rings, and can be pasted by anyone.

You can also refer to the EMF chip manual.

However, in my experience, AF confirmation is not as useful for pinning focus with a very thin DoF on a fast lens like Canon's "matte precision" focusing displays (if your camera body allows use one), or live view at 10x magnification or maximum focus and Magic Zoom to the Magic Lantern.

networks: how to assign a static IP to a VMWare guest with the NAT network adapter?

I am creating VM Workstation Linux guests with NAT network adapters and I would like some of the images to have static IP addresses.

I have read this proposed solution but cannot make it work. It seems to ignore my entries and frequently rewrites the configuration file. Also, it seems like a too complicated solution to keep more than a few images.

NB: I am using VMWare Workstation v10 and v12.

linux – How do I connect my USB-C or Type-C headphones to a 3.55mm audio adapter to listen to audio?

Due to some damage, the direct AUX 3.55 audio port does not work.
But, I want to connect my headphones / earbuds and I tried both ubuntu 18.04 and Kali Linux 2019.4 not detected on both but it is working on Windows 10. Here is the output of dmesg on Kali 2019.4 (showing pixel 2 XL Cto 3.55mm type adapter)

Recommend the proper drivers and also confirm DAC compatibility through other interfaces on GNU / Linux.

Lens Adapter – Nikon TC14E II to Tamron 70-200mm F: 2.8 Converter WITHOUT autofocus

A + TC lens is just a lens from the camera body perspective, so if your + TC lens works on your Nikon, they will work (optically and mechanically) on your GH5. So the question is whether the Nikon TC and a Tamron lens can work together.

Few people seem to be using a Nikon TC with a Tamron lens, mostly they are doing the opposite, a Tamron TC added on a Nikon lens, so if you intend to use CT primarily with the Tamron lens, a Tamron TC would be less expensive and works just as well.

How to output sound through HDMI adapter (Macbook from late 2008)?

Are there any workarounds that allow the laptop to send sound to a projector, such as using a different type of adapter?

networking: how do you determine if a USB-C ethernet adapter is supported?

I am buying a USB-C ethernet adapter compatible with all operating systems. Is there a way to verify it works for lubuntu or ubuntu before purchase?

Techkey's description says "Compatible Operating Systems: Windows XP and higher (32/64 bit), Mac OS X10.6 and higher", but does not mention the Linux kernel. (A different search result would be required that explicitly indicates manual installation for Linux 4.8 and earlier, alerting me of a possible incompatibility.)

The Flow description says: "OTG device, used without external controllers or required power."

So is Flow more likely to work than Techkey? What are you looking for?

wireless networks: problems with the KALI Linux WiFi adapter

I have a TP-Link WN722N adapter connected to my laptop, which runs Kali on a VirtualBox VM. The card is recognized, configured and, in monitor mode, you can confirm with iwconfig and airmon. However, as soon as I open something like Ghost Phisher, it still says & # 39; Monitor mode: not started & # 39;

Any ideas?

motherboard – 4-pin ATX to 8-pin ATX power connector adapter

I have a motherboard that has a 4-pin and 8-pin power connector (in addition to the standard 24-pin) and my PSU only has 4-pin and 24-pin connectors. I was curious to know if an adapter from the 4-pin connector to the 8-pin connector would emit the same amount as a connector that was a straight 8-pin connector of the PSU to mobo. I was thinking it would work since there are products available for this reason and both produce 12 volts, right? If not, could someone help me find the cheapest alternative next to this? Thanks for your time.
