You need to install Canon's EOS Utility in order to download the pictures directly from the camera. Canon DSLR cameras do not appear as generic logical drives like some other manufacturers' DSLRs. EOS Utility is included on the disc that came with the camera. Updates are downloadable at Canon's website (under the software tab, rather than the drivers tab), ...

Shutter lag of the XTi Measurements by Luk at doc-diy.net show this camera has an average* 116mS lag without mirror lockup, and a 66mS lag with mirror lockup. Fast pinewood derby cars travel about 10 feet per second (3 m/s), leading to a 7-14" (18-36cm) travel time before the image is captured. While the camera would never be used for judging, this is long ...

In addition to all the other great answers I'd like to add that the Fuji x-trans sensor used in your cameras has been known to not really meet the ISO standard. Here is an excerpt from DPReview's review of the Fuji X-T1 (which also uses an x-trans sensor): By our tests, the X-T1's measured sensitivities are around 1/2 - 2/3EV lower than marked, which is ...

I think that you are doing most if not all of the right things to ensure that you are capturing the image in camera as fast as possible. The obvious ones you have done; turn off AF and use manual mode. Beyond that I would look at your shutter release methods. It sounds like the sensor is may be placed at "the finish line", where as it might benefit your ...

You should not need the EOS Utility to connect your Canon to the Mac. Three things to check: 1) EDITED PER BELOW: The Canon 350D (Xt) had a setting on the Setup2 menu that chose PC CONNECT vs PRINT/PTP. If the camera is set in PRINT/PTP, it will not connect to the computer correctly. This is not the case with the Canon 400 (XTi). 2) Check your usb cable ...

Yes, I'm afraid this does seem to be standard when tethered (i.e. triggering your camera's shutter from a connected computer). However, the good news is that most remote shutter release cables have a "press and lock" feature for use with Bulb mode (or for continuous shooting). You can see this pretty clearly on this Canon remote: Pressing the button once ...

Canon HF-DC1 is designed for Canon PowerShot product line only and incompatible with DSLRs. You can get Canon 270EX which is about the same price range. Other relatively expensive options will be Canon 430EX II and Canon 580EX II. Also there are 3rd party (non Canon branded) flashes, which are cheap. But most of them do not have automatic (TTL) mode and all ...

The Canon TC80N3 is more suited for astrophotography. You really don't want to press and hold, you want to make many exposures, say 30 seconds to 2 minutes or more and then stack them using Registax or other type of software. I've dabble a bit in astrophotography but quickly gave it up. Here is a stack of 9 exposures, 2 minutes each, of M42. and this is a ...

I had the same issue when I bought a second hand Canon 10D EOS. Photos would only load on my old Pentium 11 MAC through a card reader, but nothing worked on my new Mac. I then had a brainwave and trawled the net for an SD to cf adapter thinking there must be such a beast. There was and it works perfectly. The adapter fits straight into my card reader and ...

Your basic issue is that you're shooting in low light with a non-IS lens (I'm assuming from the f/1.8 aperture and 50mm focal length that you're shooting with the EF 50mm f/1.8 II on your camera), and using iso 100, even at f/1.8, has pushed your shutter speed down to 1/40s. This is well within the 1/focal_length limits to show camera shake blur from ...

Sounds like I've had exactly the same problem as you. I suspect your lens is fixed by now but I thought I'd add a comment for your information and anyone else interested :-) We fixed my lens ourselves - nerve, concentration and patience was required! This was not a job for the faint hearted. I've just blogged our experience Fixed: error 99 with Canon EFS ...

There are at least two likely sources that are contributing to the variation you see. The light coming in your window could be variable if the atmospheric conditions at your location are changing between the two shots. Clouds moving across the sky, for instance, can significantly influence both the brightness and the color of sunlight coming through a ...

Your Canon has not exactly the same configuration. I suspect it to have the auto lightning optimizer on. You have the possible magnitudes: off/low/standard/high. And by default it is on standard. Try to set it to off and you should have the same results. Try also to set the white balance to manual and to the same tuning, so you can have closest colors. You ...

The XTi has a bit of shutter lag of somewhere between 1/5 and 1/4 of a second, even when fully manual (including meter, white balance and focus). Pinewood derby races are about 4-5 seconds over the 50 foot tracks. To account for the shutter lag you may need to place the sensor about a foot or two (+/-) ahead of the finish line. Try to use a wider angle lens ...

For most users, the vast majority of the time the issue is focus confirmation. Turning autofocus off by sliding the AF/M switch on the lens from AF to M will allow the shutter to release without AF confirmation. Of course you will need to focus the lens yourself by turning the focus ring on the lens. If you have One Shot AF mode selected the focus ...

The difference you are seeing is likely caused by a combination of effects from using different bodies and lenses. To compare lenses, use the same camera body. To compare camera bodies, use the same lens. Canon and FujiFilm cameras do produce images with slightly different exposures at the same settings. According to the Wikipedia article on Film Speed, ...

I'm not sure if this is actually the problem, but this is probably one thing that is affecting the brightness. Try looking at the T-stops of the lenses. (T-stop is like f-stop, but, tells how much light is transmitted through the glass, f-stop only takes into account aperture size). Your zoom lens may let less light through at the same aperture as your ...

Are you getting an Err 01, Err 99, or similar error message? In a situation like this, it's not unlikely that an error would occur. In any case, the lens needs repair. The aperture diaphragm is probably damaged, and I highly doubt this is user-serviceable.

I have had this problem before and I had to send it to their Mumbai service center to get it repaired. The repair took almost 10 days. This was almost 2.5 years back and haven't have had a single problem since then. Had to send it to Mumbai, because there was no showroom in Pune at that time :) Anyways, my suggestion would be to directly send it to the ...

It depends on what you want to light. It is very hard to get interesting photos with the strobe/speedlite on the camera -- you have to move the light off camera so that the light comes in at an angle. There are literally hundreds of books/dvds/courses on off-camera lighting. One great free resources is the Strobist site: http://strobist.blogspot.com/ Do ...

Going in a different direction and not directly answering your question: have you considered shooting star trails by using many short exposures and stacking them to create the trail? I think that's the best approach for DSLRs. FWIW, I use StarStaX on the Mac to create star trails.
