:? I just received my new Canon EOS 30d camera with a Sigma 28-300 F3.5-6.3 DG Macros lens.

style="BACKGROUND-COLOR: #000000"I charged the battery fully before using it. I can put the battery in and go through the menu change settings, etc. However, when I press down on the shoot button half way the camera turns off. The only way I can get it back on is by pulling the battery out and putting it back in. On a few settings I have been able to get a couple of pictures taken. This is with out a CF card. I have the setting for allow with out CF turned on.

Is my camera a lemon????? or does the Sigma lens not work very well with this camera???? Did I just not realize to do something?????

Help me ASAP - this is maddening

I have not experienced that particular problem with my 30D, so can only guess it to be a battery problem. UnlessitCOULD BE an electronic malfunction when shutter button is depressed halfway.

Does the battery show to be fully charged on the camerabattery meter? Could be a defective battery as I know the camera will turn off with a low enough battery.

Also double check tomake sure the battery compartment cover and CF cover are securely closed (even though you do not have a CF card installed)

The Sigma lens should not have anything to do with that problem.

I have further found with this to be that if I press the manual flash button it shuts the system down. If I don't have it set by the turn knob to any of the preset settings it works fine. If I go to the menu and set it to a preset setting it still works fine. It is only if I choose portrait, landscape, etc. from the knob does it shut the system down and of course what I mentioned earlier the flash.

The battery is fully charged I even put it back in the charger today and let it charge again. I have verified it to show fully charged.

Here is a stupid question: I can set the camera to focus but I can't zoom in at something. Where do you do this at. I haven't had a digital SLR until now. Any advice will be appreciated. I am going to go get some memory for it right now.

Might be best to contact the place you bought it and get it replaced if it is within the return period.

The zoomlens you have is probably a twist zoom and has to be turned by hand to achieve zoom.....turn the section of the lens itself where it has the focal lengths marked.The camera does not have a zoom switch or button.

Just a question. Have you experienced the problems when using a Canon Lens?

:lol: :-) :G !!!

Again Minolta was quite innovative and ahead of its time here - They had a line of Xi SLR lenses which have motorized zoom in them:

"The camera offers many more features, many of these I have never utilized. One of them is the auto-zoom function and image lock in combination with Minolta xi-lenses"


-> One of the coolest feature of theses motorized lenses are the constant aspect ratio i.e. the camera kept the relative subject size with the auto-zoom as the subject move away (or closer to) the camera

-> The other trick they had with theses motorized zoom was to pan at the WA setting to survey a wider view, but when the shutter release was pressed partway the lens would zoom-in to a preset position for capturing a particular action instead

I have one of those cameras. It is in a box sinceI moved but I really enjoyed those features on my Minolta film camera.:-)

I don't know why such an innovative company got out of the market...

I have their 9 series which is probably the fastest camera bare none... in its time :-)

The AF sensors are the largest, none of this multi-point dots business, and the only company that can produce an autofocus mirror lens @ f/8!

-> They just don't know how to sell (i.e. marketing) How many 5D/7D ads have you seen?
Sony A100 by comparison is on the front pages of numerous magazines even before the camera is out! :idea:
