Q: I have read that magic lantern firmware makes the camera better in movie recording. That depends on what you mean by 'better.' It does add several tools and options that Canon did not include in their firmware by default which are very nice to have for video recording. A partial list of which includes: zebra stripes, onscreen audio meters, cropmark ...

The chances of bricking your camera are extremely low (but not zero). I think something not everybody understands is the Magic Lantern does not install into your camera but to the SD card. My understanding is that the only change that is done to your camera is to enable the "bootdisk" flag, which is a very minor change. This flag tells the camera if it ...

Canon So far what we know based on ML work DRYOS version 2.3, release #0023 5Dm2 500d/T1i 50D DRYOS version 2.3, release #0039 7D 1Dm4 DRYOS version 2.3, release #0043 550d/T2i DRYOS version 2.3, release #0044 or #0049 5dm3 EOS M DRYOS version 2.3, release #0047 60D 600D/T3i 1100D/T3 I'm generalizing but I see in Canon P&S they ...

The answer is, it depends. Generally, firmware upgrades can Correct flaws in the original firmware. For instance, if there were a metering mistake in the original firmware, that can get fixed. Expose new software functionality. I'm thinking of CHDK here, that brings new functionality to canon powershot cameras (such as RAW shooting, timed shooting, ...

Canon wins hands down in this regard. Many of Canon's compacts can run CHDK (sources), which exposes otherwise unavailable functionalities. The more recent DSLRs can run Magic Lantern (sources). Magic Lantern adds huge amounts of functionality, including the ability to shoot timelapse and HDR within the camera, and a built-in intervalometer. Manipulating ...

Many Canon PowerShots can, using the alternative firmware CHDK (found here: http://chdk.wikia.com/wiki/CHDK)

As you can see right on the main CHDK wiki - "Temporary – No permanent changes are made to the camera." You also can find very detailed information in the FAQ here. Basically - Yes you are hacking your camera. So things can happen that the original manufacturer did not intend(if this wasn't true, you wouldn't want it anyways). But the chances of any ...

There is no way to change the firmware of Nikon's cameras other than upgrades from Nikon. For some Canon digital compacts, there's an unsupported project called CHDK that can add certain features to the cameras. Allowing Random J Hacker to load weird firmware into his expensive camera is a customer support nightmare. For every person who knows what he is ...

Panasonic DMC-LX5 and the Leica clone of it allow for raw format. However, the easiest way to see this is to visit a site, like DP Review that has a database of this information. The link there will take you to a list of 39 that support the raw option. :)

Canon There is a hacked firmware extension for Canon called CHDK, which is pretty extensive and well-documented. A lot of the features are in-camera I think, but there are UBASIC scripts for doing intervalometer type stuff. There are a lot of CHDK-related questions and answer on this site. Nikon Nikon has an official SDK which allows you to: ...

I would say in terms of order Sony Canon Sony has a repo where you can have access to the operating system, if doing embedded development is your kind of thing. You can access their current repository here. Canon because of the Magic Lantern work and the fact that they do publish some form of API to work with DryOS. If you were a end user who had no ...

Your best bet is to switch to Canon. For Canon point & shoots: CHDK. For Canon DSLRs: Magic Lantern. I use both and love them. In particular, CHDK gives manual controls to most P&S, and can also shoot raw on those models that only support jpeg.

Basically tape the last(left) three pins of the converter. EXIF distance data will likely be lost for most lenses. You will find your answer at this link: Fred Miranda Tips Page As quoted from the site: Just place a small transparent piece of tape on the last 3 pins of the converter. The tape should be placed on the left hand side of the converter ...

There is an ongoing project to analyse and de-encrypt the firmware of Pentax DSLRs:- Pentax Hack

The chdk project is the only one I've heard of.

They never made an alternative firmware for the 500D in the end. There is nothing that will improve the video recording for this camera. You could however use something like MagicLantern for other tweaks to the cameras operation. Other cameras soon came out after the 500D with the improvements people wanted for it, so it seems people gave up on finding ...

I haven't bricked my 550 by putting Magic Lantern on it... but the plural of "anecdote" is not "data", so I'm not quite sure what you're hoping to get out of this. The biggest risk is probably that if you need to send your camera in to Canon for repair for any reason, they might refuse to service it because you ran Magic Lantern on it.

I've had no problems with CHDK on a A430 doing timelapses over a day or two. I've also used it to enable raw capture. I would concur with cmason's use of the phrase "alternate firmware". It's still firmware, it just doesn't replace the factory firmware. There are warnings on the CHDK website indicating that CHDK may make it possible for you to request ...

CHDK is alternate firmware that is loaded on your SD card. It does not alter the factory firmware at all. When you start up your camera it loads this alternate firmware. When you are done with it, or don't care for it, simply put in an empty SD card and turn off/on your camera and it loads the factory firmware, just the way you left it.

When done with the contrast detect method, you can say it is software-based. That is, the camera reads the sensor, computes contrast and moves the lens according. It repeats the process until focus is locked... and then repeats it when contrast drops to reacquire focus. This is what most cameras due for autofocus while recording and is rather annoying as ...

There are reasons firmware upgrades are issued and that is to fix flaws (most of the time) or extend functionality (some times). In all cases, a firmware upgrade should never make things worst but it is just software, so it may happen, the firmware is programmed by humans too! Manufacturers often put out a list of fixed issues but sometimes are very vague ...

CHDK doesn't run on any of the Canon DSLRs, so I'm afraid that's out (though many of the benefits that it gives you are probably built in). You can get an IR remote that will actuate the shutter either immediately, or after a 2 second delay (so you have time to put the remote in your pocket for a self-portrait). They are pretty cheap on amazon (~$15). It ...

In the case of Canon and Nikon the current models are all proprietary. There are apps for Android devices that allow them to control a Canon camera via a USB cable, but the camera is not running the Android OS. Of course in certain areas the firmware includes compatibility with accepted standards such as USB, DPOF, EXIF, JPEG, etc. In the past some of the ...

If you shoot video you'll want to look into the Magic Lantern firmware. It's still very much a WIP but they've added manual audio and meters and have zebras on the to-do list. http://magiclantern.wikia.com/wiki/Magic_Lantern_Firmware_Wiki

I've also tried to find a CHDK-like software for Pentax, probably the best Pentax firmware hack project is Pentax Hack. They were able to decrypt several Pentax firmwares, and modify a few things, like turning on debug mode. Although the project supports several Pentax DSLRs, unfortunately it does not support K-x.

In Magic Lantern under 'prefs' under 'image review settings'. Turn off 'quick zoom' All done. Enjoy.

I seriously doubt there are any technical reasons. High-end compact cameras use similar technology and do allow manual control. Any feature that is added to a product will make it harder to understand. If the target market for the product does not need the feature, it will not be added. For compacts, target market is the people who just want to snap a photo ...

As far as I'm aware it doesn't, CHDK only runs on the 400D and lower (due to the firmware chipset it ran it was fairly hackable), and Magic Lantern starts on 500D and goes up from there.

I had tried Magic Lantern 2.3 on my Canon 600D and I must say that I wasn't satisfied. Yes, it provide some of the cool features like HDR Video, Zebra Strips, Magic Zoom etc but I noticed the following negatives about using it: The battery life dropped drastically. Camera was running warmer. Exposure in LiveView was all messed up. I was not able to use ...

Short answer to the basic question: no, there's no hack to do this on the K-5 that I'm aware of (and I've been a Pentax shooter pre-digital). As to the second, sort of, question: yes, there is some software hacking. The Pentax line does have a debug mode and people are accessing it, details can be found on the Pentax Hack site, though I don't think they've ...
