parasti iesaka iznemt baterijas (ABAS, lielo un mazo, kur atrodas, prasi Gūglei) uz minūtēm 15 (drošības labas uz 30) - tipa pilnais resets; vai arī pārlikt firmvari (dabonama Canon lapā) - ja nepalīdz, droši vien tikai Canon centrs var ko labot - bet remonta cena droši vien līdzināsies 300d tirgus cenai. Tur parasti maina veselus mezglus/blokus, ne ķimerējas pa sīkumiem.
Tā ka pērc tik jaunu, lai var karnevālus sabildēt ka grezno!
pamojemu ta ir tipsikaa 300d slimiiba, spogulis neceljas augshaa taa peec aisedz matricu un tapec bilde ir melna, servisa noplesis normalu kapsotu, var nest akaadam kuljibinam buus vismaz uz pusi letaaak, ir veel opcija pasham taisiit ja rokas taisnas, aparaac jaizjauc pilniibaa un japielimee jauna kajinja spogulim ko var uzmeistarot no saspraudes!
google google google tu ir pamaaciibas kaa to dara ar visam bildeem aprasktiem un visu pareejo! var pat atrast kaa 300ajam nonjemt UV stiklu un aizvietot to ar ne UV stiklu...
Tātad, īsumā, izrādās, ka Sigmas un Tamroni priekš Canon patiesībā ir bulšits - īstenībā saderība nav oficiāli apstiprināta un testēta. Canons nekādu info šiem (un visiem pārējiem) ražotājiem nedod, tie paši ņem un taisa reversinženieriju, un tad - kas sanāk, tas sanāk...
Kāds zin kaut ko vairāk par šādu faktu?
This is a second attempt to post a reply. Here is what I recieved from Canon about the err 99 on my 10D using a Quantaray tech-10 24mm macro. It works in my D30 but not in my 10D.
"On all of Canon's EOS cameras, any Canon EF series lens is designed for the camera. Canon does not support non Canon equipment. It has not been tested and we do not know the effects. It could cause malfunctions with the camera.
A variety of lenses from third-party manufacturers - Sigma, Quantaray, Tamron, and others - are available in Canon EF mounts to fit Canon EOS camera bodies. However, contrary to popular belief, these companies are not "licensed" to produce these lenses; instead, their designers must basically take apart and analyze EOS cameras and lenses, and then "reverse-engineer" them to fit and operate on EOS camera bodies.
Lens to body communication
All Canon EF lenses have a microprocessor within the lens that provides a number of items of information to the camera. When you turn on an EOS camera (film or digital) the camera and lens communicate, and the camera "knows" the lens's focal length, if it's a zoom lens the actual zoom setting it's currently set to, and the maximum and minimum apertures, among other things. When the camera is activated, this basic information is transmitted to the camera body's main processor.
When the autofocus and light metering are activated by pressing the shutter button halfway down, additional communication is carried out, chiefly signaling the aperture control motor within the lens to stop the diaphragm down to an amount determined by the camera (or the user, if the camera's used in Av or Manual exposure modes), and a start signal is sent to the lens's built-in focusing motor to begin driving the focusing elements of the lens for autofocus. This is only a thumbnail sketch of what occurs between body and lens. Many additional items are communicated back and forth between the time the camera is turned on and the moment the shutter button is fully depressed.
Communication errors
Whenever an EOS camera cannot complete electronic communication with a lens, or detects an internal disturbance, the camera is designed to lock-up on the first attempt to fire the shutter. Usually, a dead-battery icon blinks in the same manner as a "check engine" light in a car. This assures that there's almost no possibility of a user shooting an entire wedding or vacation, for instance, with a lens that's not stopping down its aperture properly or otherwise not working with the camera properly.
Third-party lenses
The makers of third-party accessory lenses are not given this information when Canon introduces new features or improves the performance of its cameras and lenses. It's up to them to continue to "reverse-engineer" their equipment to enable it to continue to work on new EOS bodies as they're developed. Since Canon designs our own processors and all electronics within the body and lens, we have been able to maintain backward compatibility. This is one of the many advantages of choosing a Canon EF lens.
When changes in communication result in a third-party lens that now produces errors, it's up to the makers of that lens to update the equipment to work on the EOS camera in question. Again, Canon's own EF lenses work without modification.
The meaning of "fully compatible"
Many third-party lenses with EF mounts are sold to customers with the claim by store salespeople or even the lens manufacturer that they're "fully compatible" with all Canon EOS cameras. Canon, Inc. in Japan and Canon USA offer no rebuttal to those claims.
Any compatibility is based on the reverse engineering we described earlier in this document. And if a user mounts this lens on a certain Canon EOS camera and it locks up, it's up to the user to contact the lens manufacturer (after verifying it's a lens issue; see below) and tell the lens maker's service department, "make it right."
