The camera shutter is a mechanical part, and like all things in the universe, subject to eventual failure. You can see How many actuations are "too many actuations"? for some information on just how many clicks a typical shutter mechanism is good for (depending on the model, between 50,000 and 400,000). But note that these are just estimates based ...

This is normal. The software you are using is showing you the JPEG preview embedded in the RAW file, which in every case I know of the same as the JPEG generated with RAW + JPEG settings. (Depending on the preview, the resolution may be reduced and compression higher, but you won't notice this in a quick on-screen comparison.) For more on what a RAW file is ...

It sounds like the scene your were framing was outside the operating range of your 80D's meter. It's rated for EV 1-20. At ISO 100, EV 1 is equal to f/1 for 1/2 second.¹ The maximum ISO for the 80D is 25,600. That's 8 stops higher than ISO 100. f/8 is six stops darker than f/1. You report that 30 seconds was a good exposure time for ISO 25,600 and f/8....

So - which system is best for use with FD lenses? Neither EF nor MFT are ideal for adapting FD lenses. To adapt FD to EF requires corrective optics with a 1.4x multiplier. MFT has a 2x crop factor. With a 0.72x focal reducer, this can be converted to 1.44x. If you intend to use adapted lenses extensively, consider an APS-C or full-frame mirrorless camera. ...

A speed booster does not change your sensor. Not in any shape, way, or form. It changes the size of the image circle projected by your lens, making it smaller. The usefulness of a speed booster is to combine lenses that cast large image circles, such as lenses made to be used on full frame cameras, with camera bodies that have smaller sensors. By reducing ...

Because when you look at an image on your screen you are almost certainly not looking at a literal depiction of the information contained in a raw image file, you are looking at one of near countless possible interpretations of the information contained in the raw file. Many of these interpretations are equally valid as a "correct" way to process the ...

You do not have a 1150 mAh (milliamp-hours) charger. There's no such thing. It might be an 1150 mA (milliamp) charger, which means it's only providing 1.15 amps of charging current. Some batteries require a minimum current to charge very well. My Samsung smartphone, for instance, requires a 1500mA charger. If I try to use a 700 mA (0.7A) or 1000 mA (1.0A) ...

There are currently 2 types of Canon STM lenses: Fast and silent Lead-Screw Type STM and slow and noisy Gear-Type STM. The Gear type STM lenses (40mm 2.8 STM and 50mm 1.8 STM) work fine in manual focus with the EF-M, but the Lead screw type lenses (10-18mm STM and 18-135mm STM) will not manually focus. (I also tried the new 18-135mm Nano USM and it also ...

A lot has to do with how the "presets" are written and at what stage in the imaging processing pipeline they act upon the image. There can be a wide variation from one "preset" to the next. "Presets" are merely someone else's list of settings applied in a certain order determined by them when they recorded the preset. "Presets" usually assume that the ...

I assume the horizontal focal length in this video should be around 35-50mm on full-frame. You own a APS-C sensor size camera with a crop factor of 1.5 which means you can achieve this field of view with your lens at approx. 24-35mm. The thing is the "mood" of the clip is not only about the focal length. Notice the blur of the background in most of the ...

While this could be a Lightroom Classic bug, there is a way to "fix" it. In the Develop Module, go to Lens Corrections, change the lens profile to Adobe (Canon EF 17-40mm f/4 L USM), then select Save New lens profile defaults from the Setup combobox located below the Enable Profile Corrections checkbox. Newly imported photos taken with that lens should now ...

Don't use your YN560 IV in the hotshoe. Instead, use it as an Off Camera Flash. Bounce it off the ceiling or use it hand held. Use your 2000D built-in ETTL flash to trigger the S2 Optical Slave Mode on your YN560 IV. S1 mode fires when ever it sees a flash which is a problem with ETTL preflash. S2 mode fires on the second (Main) flash and ignores the ETTL ...

Michael C gave you a really nice answer about the speed booster. But I wan to address the other question. Can anyone give any advice? Well, stop reading things about the "disadvantages" of a cropped sensor because they are bothering you for "some reason", but it does not look for any particular reason. Take your camera and shot. Enjoy taking photos, ...

The Godox XPRO-C and X1T-C wireless radio triggers are known to work with the Canon bodies that do not have an ISO compliant center pin. Of course your Yongnuo can't be controlled by Godox triggers. Unfortunately, none of the E-TTL compatible (which seems to be the key to working with a camera without a center pin) Yongnuo triggers use the same protocol ...

I have the RF 24-240 lens for my EOS RP. I also have EF 24-105 f/4L mk1 lens. I don't have the RF 24-105 f/4L lens. The RF 24-240 lens has several quirks you need to know: Lack of weather sealing Lens hood needs to be bought separately Manual focus switch is missing and you need to set it in the camera menu The focus/control rings are combined into one The ...

What do you think the mirrorless RP can do for the type of photography you do that your current 6D Mark II can not? If you can't answer that question then you don't need to upgrade anything. If you are dissatisfied with your current photos and think that a change in gear will make you a better photographer, please see: Does the camera matter? When should ...

How important is "image quality" to you (sharpness, aberrations, distortion, light falloff, flaring, etc)? You can compare the lenses at The Digital Picture. Superzooms usually... Are more versatile. They cover a greater focal length range. Are more convenient. You don't have to change lenses. Are more fun. You can take pictures without worrying about ...

A count of just 15 seems unlikely on a used camera! No, it won't turn off at some predetermined number. It's just, like an odometer on a car, an indicator of how much it's been used. Interesting when determining the resale price perhaps. But no, shutter replacement if it DOES fail is not a DIY job, and is very likely not economic.

Optical triggering by the camera's built-in flash can work, but also has significant limitations and can be more frustration than it's worth. Theoretically, this can be triggered by radio off-camera, which would be a good use. Unfortunately, it seems that this Yongnuo model only works with triggers which also won't work with your camera. Therefore, I ...

I see the FD to MFT adaptor doubles the focal length, so does that mean it’s not worth it? None of my lenses would be particularly wide any more. So, uh... buy a wide angle lens or two to complement your existing lenses? On the other hand, I’m having difficulty finding resources for using FD lenses with an EF mount - surely if there’s a full frame ...

Normally I'd respond to questions like this with, "Buy either one. They're both good enough." But for astro work, there probably are at least three considerations you should be aware of. This is particularly the case since you have said in a comment that you are planning on using it with a 12 inch telescope, which usually means deep sky work rather than ...

First, your price comparison is not right — as I look on Amazon and B&H Photo right now, both are right below $400, with a three dollar price advantage for the Nikon camera. That's not a difference to make a big deal of. Second, these automatic comparison sites are terrible. They don't use any human judgement and focus on emphasizing nitpicky ...

For astrophotography, you'll be looking at low light performance. That requires a good fast lens (usually a prime), and the ability to have actually useful high ISO. The specs mention neither. The high ISO on Nikon might suggest the Nikon is better, but the high ISO could be just so noisy that it's useless. So, back to the researching stage: what is your ...

I own a Canon Rebel T7i ... Is it a good idea to purchase a speed booster ...? There is no focal reducer available for your camera. ... should I just purchase a 35mm prime at f/1.4? Not all 35/1.4 lenses are the same. What do you need it to do? If you were to switch to a crop-sensor mirrorless system, focal reducers could expand the usefulness of ...

You can extend the Wifi range with a good antenna at one end (possibly the PC end). Technically that would be a Wifi dongle with a removable antenna (like possibly this one where you remove the provided antenna and connect a directional one (examples only, no quality implied). And with some luck the dongle has already more range with its provided antenna ...

The reason there is a separate profile is because prior to the 1D X series, Canon's 1D series were 1.3X APS-H cameras that had a different field of view from either their full frame 1Ds and 5D series or their APS-C 1.6X crop bodies when using the same lens(es). Adobe should more properly label it something such as [EF 17-40mm f/4 L (1.3X APS-H)]. While ...

You can't change the focal length by script because AFAIK there are no DSLR lenses wit an electric zoom, so the camera itself cannot control the zoom. You would need an external rig with a motor to rotate the zoom ring on the lens, and control that motor from the same script that controls the other parameters.
