Camera problems

[mugas]

Hey. I have a Canon that lately is not working properly. In Automatic the focus...well don't focus and the camera don't shoot. In manual it works ok.I don't know if it's a cleaning problem or what? Anybody knows or where i can take it to repair?
Thanks

The camera is 600D. I have tried with other lens that i have and it seem ok with no problem. Also i notice that this only happens when the camera is on vertical view. On horizontal one it seems to works always fine...Any guess?

If it works with one lens but not with the other... could it be that you have lens problem instead of camera problem?

Throw it away and get a Nikon.

Is the lens firmly attached? Does the lens try to focus at all?

Thanks for the tip of the Nikon:) Next time i will do it.
Yeah it try to focus and it focus but then doesn't shoot and it start again the focusing...

Yeah i believe so, just trying to erase all other possibilities. So if it's the lens, you think it will be fixed and worth fixed?

depends on the lens and your demands (ease of use, quality, other owned lenses)

[sky2]

As it occurs only in the vertical view, I doubt if its problem with the lens. May be the lens is not able to freely move in that position or may be it just cannot find the focus (depending on the subject etc). You can try to remove it and attach again to see if that helps. Also you can try to test your lens on another body (find some of your friend having a Canon camera) etc.

Depends on your lens, if its a kit lens, you should get a better one anyway.

I doubt repair is really cost effective (unless it is the lens and it is an expensive one. I guess not).

[Rip]

I'd actually get both the body and the lens quoted if it were me. Contact Canon themselves and ask about where you can take them. Good quality gear is always worth having quoted.

The body is a four year old consumer model. I did not comment on the lens, but if it is from the original kit, then it is hardly worth much. Even getting a repair quote tends to cost.

Oh and "buy a Nikon" doesn't solve the problem.

That was a complete joke (... or may be half. Hint: click the link). However have you used OP's camera (600D)? Do you know how outdated sensor it has, hows the image quality compared to the similar model from Nikon (lets say D5100, or even basic model D3200)?

I can tell you that the two best brands of lenses for SLRs are (1) Minolta/Rokkor - no longer a real option - and (2) Canon.

May be you can tell which Canon Lens you are referring to, and then compare its performance with the parallel lens from other brands?

As for the camera body itself, I would choose Canon.

Canon what? If you'd ditch Nikon D7200 to use Canon 600D, that would be silly

I also know what professionals use.

...and what they use? Tell me more, I'd like to follow them too.

Look at the next sporting event with those huge lenses and count how many are white.

So the photography is all about the sporting events only? May be look at some other types too, and also see the low light performance?

No hard feelings, I just had nothing better to do so wrote the post above. But hey, try Nikon someday

[sky2]

Seriously, do you get offended that easily or are just having a bad day? How did I dick around, I just gave you my opinion and you are just being rude. May be re-read the post when you are calm down? I didn't claim anywhere that I'm an expert in photography, neither I said Nikon is better than Canon or vice versa. I just think that its silly to generalize the brand without being specific.

Just to rule out the long shot, this can happen if you use the wrong kind of polarizing filter on a digital SLR. Offhand I don't recall whether it's only SLRs or any digital camera. Or is it only the non-SLRs, focusing off sensor contrast, now I'm suddenly unsure.

And it's not just hypothetical, I've seen it happen, I just don't remember with which of my cameras.

You haven't been experiencing all this with a polarizer on that one lens, have you?

[Querfeldein]

This is a very good point. A linear polariser can throw off the auto-focus (for SLRs like the 600D in general, not for mirrorless cameras), and it can depend on the orientation. The light that bounces off the mirror into the autofocus module is polarised, and if the light happens to arrive at the mirror at an orthogonal polarisation, the autofocus chip will effectively be blind. However, you don't just have a linear polarising filter mounted "by accident", so I'd be surprised if this turns out to be the solution. If the camera can autofocus correctly with other lenses, a mechanical fault of the lens seems most likely.

I won't say anything on the Canon / Nikon debate

[AldenG]

Before digital, "circular" polarizers were rare, for semi-obvious reasons. So while you have to go looking for linear polarizers today, if you just happened to have an old polarizer of the right diameter in your bag, it would likely be incompatible with AF.
