So what happens to all the dust thats in the camera and the next time the shutter opens?
Turns into extra pixels.
I always do that too. There is a reason for doing it, but I can’t remember why.
Ooo little black blobby pixels
It makes it less likely the sensor can get damaged when changing lenses. It won't stop dust getting on the sensor nor would it claim to, I expect.
The shutter is actually More fragile then the sensor
Have you ever damaged a sensor changing a lens? If you did damage the filter wouldn't the cost be similar to replacing the damaged shutter?
But on that argument, is the mirror box cheap to replace? Why isn't that flipped up when changing lenses in DSLR?
I am sure in film SLR the mirror is down too and the shutter is down. What are they protecting? thin air?
Will canon seems to be the main focus of this thread, I managed a couple of shots manually focusing with the 135mm. Epic sunset this evening while feeding the squirrels. Fingers crossed for another tomorrow.
Couple of jpegs
I'll use my gear in rain and snow but one problem I rarely see mentioned (in fact probably never mentioned) is that water/snow can get on the lens and spoil the shot as you press the shutter. For me this has been a bigger problem than a lack of weather sealing as I've never had a weather related failure but I have had shots spoilt by snow or water landing on the front of the lens.
Just for fun, a couple of before and afters...
Both of these were ok when looking through the vf and the problem occurred as I took the shot
Canon 20D and Tamron 17-50mm f2.8.
The rumor site has a bit on the batis 40mm f2...
So you don't want the cameras to get better
Why are you against progress. Knowing weakness of your gear is as important as knowing it's strengths.
I suppose you'd know that if you tried using your gear
It's only an issue if the water seeps in through the battery door which has been shown in tear down and tests.
Just because you guys can't see a use for it doesn't mean it's not necessary for everyone. I have used as wide as 21mm at macro distances for shooting flowers. Link my in signature.
Entire range of normal lenses. I don't see any PF or DO lenses.
To be honest photos of flowers bore me
Ok but that's besides the point
Those are ef and f mount right? Enjoy them on your adapted 3fps milc.
Why haven't you bought your canikon yet? Found the weaknesses in them have you.
Just a quick question. The 70-200 GM makes some strange noise when I turn on the camera. Hard to describe the noise other than it’s a strange kind of vibration rattle buzz lol
OSS kicking back in I imagine, I have other lenses that do it. It's usually 'docked' when the camera is switched off to save the internals moving around in transit etc.
Does it with OSS off too. It’s more or a slight buzz kind of noise.
Could be a horse fly trapped inside
This is pretty much the only thread I have been participating in recently. I keep getting notifications to my phone saying I have messages. 7 in total now. Yet I see no messages in my Inbox.
Are you sure it isn’t the sensor cleaning sounds louder with a longer lens
Was mentioned here
Focus motor turning off and on?
That’s probably what it is.
I don’t have this problem as I only have 1 lens
Haha I only have one lens for my sony at the moment. But I always turned my Nikon off when changing lenses
Just thought it was best to check with other owners!
If transfer me £5K I'll happily do so.
I am not made of money unfortunately. I rely on used market greatly. Same reason I still don't own a sigma 35mm ART.
Me too. Probably will be light, compact, with discrete autofocus and a quality distagon ?
l'll dislike the finish cos it'll be like my 25mm,
So can 70-200 GM owners check this for me?
This is my start up and shut down noise...
Reminds me of the old sigma macro lenses image stabilisation noise.
@Riz_Guru can you take yours out of the cabinet and box and attach it to your camera. See if makes the same noise.
I will do
I'm sure its all fine, but be nice just to clarify! My mate has said his 70-200 F4 does it but maybe not as loud.
But once you have located the key and unlocked the cabinet I would appreciate if you could let me know!
It'll make a groaning noise, like someone waking up from a long sleep!
And thatis just opening the cabinet door
Guessing he is putting on the white gloves and putting the dust extractor on full before the cabinet is opened?!
I'd expect a nice shirt, tie, trousers and shoes and a decent hair cut too. In fact this event demands a full make over.
