There are three main methods by which a dSLR/mirrorless camera can be used as a webcam. HDMI capture HDMI capture requires two things: that the camera can output "clean HDMI"; that is HDMI that doesn't have camera control overlays all over it, and an HDMI capture device to turn the HDMI output from the camera into a USB webcam input to the computer....

inkista has an excellent answer above. My Panasonic GX-80 doesn't support 'Lumix tether for streaming' - but it does have a Wifi function allowing you to watch a live preview from a smartphone. Over the course of a caffeine-fueled long weekend, and helped by the writings of people who'd tried similar things before me, I was able to get the wifi preview ...

The suitability of live-view and mirrorless camera options for use with long telephoto lenses comes down to ergonomics, practice, and context. The biggest factor is likely how you're viewing, sighting, and stabilizing the camera, vs what you are photographing. Viewing a non-tilting rear mount screen is probably the worst option in nearly any context. You ...

Are there any adapters for this lenses to the MFT mount that are relatively cheap (less than 50€)? Search on your favorite auction site for "M42 MFT adapter". Sort by price. Consider limiting results to local sellers. Another option is to pair an M42-EF adapter with an EF-MFT adapter, which would open up some other options (other mounts, focal ...

Using native lenses is bound to give you a better experience than with a mount-adapter. Assuming, an adapter that is purely mechanical - as most are - there will be no reduction in image-quality because all these adapters do is create space between the mirrorless mount and the flange distance for the DSLR mount. Although image-quality is bound to be the same,...

Let's talk about lenses first. You can get cheap lenses in almost any mount, mirrorless or (D)SLR. You can get very expensive lenses for any mount, mirrorless or SLR. You can get a lot of lenses in between for either type of camera. Since most SLR mounts have been around decades and most mirrorless mounts have only been around less than a decade, there are ...

The "closer to the sensor" advantage of which your friend speaks has a lot more to do with the distance between the sensor and the flange upon which the lens is attached, referred to as the registration distance (or colloquially as the flange-focal-distance) for a particular lens mount system, than it has to do with the different distances to the ...

First, consider a simple one element lens, like a magnifying glass. The distance from the lens to the "sensor" is the focal length. A long focal length will be more distant from the sensor. (this is the "thin lens" formula). However, such a simple lens has aberrations, optical faults (primarily, a single element cannot focus all colors ...

For Mac users - a new webcam app. I'm adding this to existing 'webcam' questions for future searchers. I am in no way affiliated with this product or the company making it - this is a simple user to user recommendation. I just discovered this today, announced on DPReview a new product called Cascable Pro Webcam £40 [£30 for the first week to 24 July 2020] I'...

If you have a Canon or Nikon camera, and a Windows PC, Sparkocam might be a solution. It enables you to connect the camera via USB, and use the camera for for example Skype. I have used my Canon EOS 700D with SparcoCam, and it works well. It is free to try, but costs $49.95 for a standard license for either Canon or Nikon (upgrades for 1 year). From Sparsoft....

On-sensor PDAF works much more like a split prism focusing screen as compared to the DSLR's dedicated PDAF sensor. A pair of photosites (pixels), or a pair of photosite groupings, have their lens(es) biased to intercept opposing virtual images (left/right, upper/lower, or both), and when those virtual images differ in phase (angular offset/position) the ...

[I know we're straying into the world of video here, but I feel it's still relevant] Why is live view harder than "TTL"? because you are not using the senses you were born with - that your eye & hands are easily co-ordinated to match direction, distance, speed & focus [of attention, not sharpness of image]. Catch a ball. No maths required, you just ...

I've the Tamron SP 70-200 2.8 G2 lens and can confirm it won't work on the R5 which arrived yesterday. I've contacted Tamron in the hope they will sort it out. I've the tap-in console and have the latest FW on the lens.

As the other answers have hinted at, this isn't so much about the difference between an electronic viewfinder and an optical viewfinder as it is about the different ergonomics of using an eye level viewfinder held in a constant position relative to your face and eyes versus a screen on the back of a camera held a foot or so in front of your face. When you ...

Are there any adapters for this lenses to the L mount MFT mount that are relatively cheap (less than 50€)? Yes. You probably need an M42 to micro four-thirds adapter. Fotodiox makes inexpensive ones. You will, of course, lose the ability to control focus and aperture from the camera body (no electronic communication) and there won't be any lens EXIF ...

By chance I also have a Praktica kit left by my father, and some Micro 4/3 gear and adapters. I also have an old Pentax lens which works just fine on the Praktica. I don't have an adapter for this combination, but Praktica and old Pentax were so called M42 mount, so what you want will probably be called an M42 to micro 4/3 adapter.

As with many things, the marketers have tried to convince us that bigger, more, or higher priced is always "better". Most of the time in photography quality trumps quantity. The term AF "point" has always been a bit of a misnomer. Rather than a single discrete point with no dimension, all AF systems have areas or zones of sensitivity that ...

Assuming you mean one of the Canon EF 70-200mm lenses with a Canon EF 2X extender and an EF→RF adapter, yes you may. But honestly, depending upon which EF 70-200mm lens (there have been seven different EF 70-200mm "L" lenses released between 1995 and 2018) and which version of the three 2X extenders that have been released over time in the EF ...

The difficulty of pointing is a combination of both the different body position when looking at a screen and the inherent latency in a LCD display. One option would be to mount an external viewfinder to the hot shoe on the camera. There are many models available, search for "external optical viewfinder" or "hot shoe viewfinder". Such a viewfinder will not ...

I have experience with several Tamron EF lenses + EOS RP, including Tamron EF 70-210mm f/4 and Tamron EF 100-400 f/4.5-6.3. They usually work just fine (aperture, stabilization, focus) with latest firmware if Tamron says so. However, the AF scan speed is uselessly slow in situations where the lens+camera combination cannot find focus. In practice, this does ...

So... I stumbled upon this video showing how the Anti-Shock mode works on the E-M5 Mark II and it turns out my question was based on an incorrect assumption. This assumption is in the way a focal-plane shutter traditionally operates. As implemented on most SLR cameras, whether digital or film, after an exposure, both curtains are returned to their original ...
