I recently watched this video about using a digital teleconverter. Years ago the wisdom was to Never use one. However I am now very tempted to try and set it up and use one of my Custom modes. Have any of you tried using the digital teleconverter in your camera. It will only give you a jpeg file, and can not be used for BIF shots.
This is the link to what I watched:

Digital "teleconverter" is a misnomer, it is simply cropping the image and discarding pixels.

What do you think is the advantage of cropping in the camera as opposed to cropping in post? When you do it in post, you can tweak it to exactly the crop you want, which you can't in camera. And the restriction to .jpeg makes it even less useful.

Also when you crop in post you don't always have to keep the middle of the frame. You can choose to use the left, top, right or bottom section of the frame.

Sony's "Clear Image Zoom" seems to work better than it should!

I did comparisons a few years ago with my Olympus OM-D EM-10 Mark II with Olympus M.Zuiko Digital ED 75-300mm f/4.8-6.7 II Lens.

Click here for the thread. Sharp-eyed folks saw the difference.

Why not set it up and try it for yourself? Digital film is soooo cheap

Bill, it takes thousands of hours to learn all the idiosyncracies of UHH

I think it would be a bit easier if they eliminated the never or very seldom used sections. Then a short list with descriptions of sections would be easier to understand.

Have watched the video and he makes a strong case for the use of digital teleconverters. I have been using DSLRs for many years and like you have always understood that photographs taken using the digital teleconverter function seldom resulted in a good photograph. I wonder, however, if his findings would be the same for all camera makes and models. Why not buy a teleconverter instead? Are the results the same for FF cameras as compared to DX. Seems to me there needs to be "a whole lot of testing going on" before we will really know whether "to DT or not to DT"

That is all very true, but if you watch the video, and I watched most of it, He makes a case for the digital teleconverter, so Much so that I will give it a try. It doesn't mean that I will like it or even keep doing it, but I certainly will try it

As a follow up to my previous post. Best I can find, my Canon EOS RP does not have the digital teleconverter function. Anyone knows differently, please let me know.

Jeannie--I don't click on links, so have not seen the video that you are asking about. That means that there's a possibility that I have a different interpretation of "digital teleconverter" than what you are asking. But I have a pretty good idea what you are asking about and will reply based on that.

Each of the cameras that I shoot with offers a choice of shooting formats that include options which use less than the full area of the sensor. All of my camera manuals discuss those format choices and provide information on why they might be used. Of course, one of the first reasons is to simply "pre-crop" your captured images so that your subject will be reproduced larger on a given screen, display, or printer. That can be very convenient if you don't post process your images and don't have a long enough lens for what you are wanting to do. The second reason is that you simply may want to produce an image with a smaller file size (without giving up resolution or compression loss). This may be to make that image immediately emailable or to fit upload file size restrictions imposed by some archaic websites. But a third reason, and one that for some reason no one seems to want to acknowledge or talk about, is that with some cameras, choosing a smaller image format may allow for a faster continuous shooting rate. It will almost certainly allow for more images to be accumulated in the buffer before shooting is forcibly slowed or stopped. (On my D500, the buffer increases from 22 to 30 exposures if I choose the "1.3x" format.)

Some of these benefits may have no value to you. Others may provide you with some important new shooting capabilities. You should check to see what your manual has to say. Then, as you have already decided to do...experiment.

What Is a Digital Zoom on a Camera?
Digital zoom takes place electronically, and the “optics” change automatically. Digital zoom is a method of cropping an image to get closer to the subject. This function trims the edges of the image and enlarges it digitally, thus “zooming in.”

Your camera uses more pixels from a smaller area on your sensor. As a result, digital zoom results in lower image quality than optical zoom if you use this feature.

How Does Digital Zoom Work?
The camera does not do any zooming. When using this feature, you are essentially just cropping your image on camera. That is why when you zoom way in with digital zoom, your image can become pixelated.

Using digital zoom is as simple as when you press the button to take a picture. You do this by pressing buttons on the back of your camera or as part of the menu system. In most cases, you do not get to choose how much zooming occurs digitally since this will depend on resolution and file size factors.

This, however, is opposite from how a traditional optic zoom works. In this case, a lens physically changes its focal length to do the zooming.
