I have an opportunity to get a 14-50mm Leica lens for my Olympus camera for a rather attractive price. The lens has built-in anti-shake system; however, I'm planning to upgrade to Olympus E-510 body later, which also has anti-shake.

So I'm wondering what happens if you put an anti-shake lens on an already anti-shake camera:
- The anti-shake suddenly becomes 2x as efficient?
- The anti-shake systems cancel each other and I'm screwed?
- Only one system works at a time?
- The camera asplodes?

if its what im thinking then the lens will try countering a shake, then the body will try the same thing so it will overcorrect, then it will continue, basically making the shake worse than it was before.

You could just turn one of the ASR (either from the camera, or lens) off. Typically lens based works better.

It'll set up a harmonic resonance pattern in which the camera stays perfectly still but *everything else in the world* starts shaking.

For the love of God, man, don't try it. You'll end us all.

I've been thinking that several camera manufacturers got themselves in a really stupid pinch because of the two types of anti-shake systems...

Panasonic-Leica has Panasonic's lens-based AS technology, so they're making lenses with AF.
But their next SLR has to be based on Olympus hardware again, and that hardware includes sensor-based AS now. If they don't dump that feature, there will be inconsistency with their own lenses; if they do, it will look fucking stupid. (However, they already screwed up like that with L1's viewfinder and don't seem to mind)

Canon and Nikon have been producing lenses with AS for a long time now and marketing them mostly to pros. But now the low-end market demands AS too, and lens-based AS is too costly for that.
So they have the choice: make a sensor-based AS system, lose profits on lenses and screw over the pros who already paid a fuckton of money for AS, or don't make it, lose profits on low-end cameras and screw over amateur Canon/Nikon fans.

you dont need AS,IS, or VR on short lenses. People need to learn it dosent do that much at wide angle. Zoom is where it helps the most, and Nikon just made a lens that does that. 55-200 VR for $250

You DO need AS/IS/VR on short lenses. The difference is only in shutter speeds at which AS will be useful.
For example, shooting handheld at 1/100s requires AS only at focal lengths of 100-200mm or more; but at 1/10s, AS is very helpful even at 30mm.

Oh Jesus Christ... just hold your fucking camera still. If you need image stabilization with a 30mm lens, you need to go to the doctor and lay of the meth.

dude, chill the fuck out. I also agree with VR can help with short focal lengths, if i'm shooting in low light, the combination of HIGH ISO + LARGE APERTURE + VR would reduce the chances of having a blurred shot.

but meth is delicious!

VR on normals and wides is kind of silly. I'd rather have less things in the lens to break. I know I'm a cranky old man with a monopod but seriously, use a monopod or tripod. Learning proper posture and breathing helps, brace yourself, foo

I just took these a little bit ago for demonstration, that's 42mm(effective) at 1/20th. Are they surpremely sharp? No.
Are they more than usable? Of course.
They're actually a little softer than they could be because that's the jpeg ugly version with in-camera set to no sharpening.

It's not rocket science, practice good technique!

I'm 100% for people actually learning how to hold their camera.

But that doesn't negate the use of IS/AS/VR (could people just decide on one term, please?) at all. I can manage a perfectly clear picture up to about a little over second with IS/AS/VR if I try really hard. I can't do that without it.

Longer the focal length, Less the in body Anti Shake helps (It can't because of the properties of the light entering the lens))
Shorter the focal length, The More the In camera anti shake helps

Longer the focal length the more awesome the lens Anti shake is.

Now try that without a monopod or table to lean on. And at 1/8s.
I know shooting at such exposures isn't too common and is useless for moving subjects, but who knows when you might need it.

Also, I haven't heard yet of cameras or lenses failing due to VR, since it's rather sturdy when inactive and locked. The shutter and mirror assembly is also a delicate mechanism, probably more delicate than VR coils, but we still buy SLRs, don't we?

Not quite sexy on a 2x crop factor olympus.

>>55582

What? 2x! You're right, that's queen-of-england unsexy.
>> ac !!VPzQAxYPAMA
>>55584
I dunno. 28mm's one of my favorite focal lengths. Not as sexy as a real full frame 14mm would be, but still nice.
>> street-pirate
If the olympus had a 1,5x crop factor, you would have been able to get both ultra wide or the 28mm you like. Sure, 28mm is nice, but it's better to be able go to 21mm if you like.
>> ac !!VPzQAxYPAMA

One of the reasons I think the 4/3 system is teh suck.

And since the whole system is designed around that specific 2x-crop sensor size, there's no hope of one day upgrading to a larger sensor like you can with the Canon system (or even Nikon or Sony, although they don't yet have full-frame cameras)

Granted, Canon and Nikon are stuck with the max of a 35mm-size sensor, but at least they have somewhere to go.

There are both good and bad sides to the 4/3 system. Olympus was quite foolish to aim it at the pro segment at first; it really belongs to the amateur market.

Pros:
- cheaper
- lighter telephoto lenses
- dust reduction system that actually works
- live view (not a big advantage in its current clunky state, but it has some uses)
- shorter flange focal distance means that you can use almost all non-4/3 lenses via adapters (in manual mode, of course)

Cons:
- Smaller sensors = more noise (E-3x0 and Panasonic L1 suck, E-4x0/5x0 don't suck, but are still worse than comparable Canons and Nikons)
- Native wide-angle lenses and primes are expensive and/or scarce (Olympus promised a cheap wide lens... "somewhere in 2008")
- Cannot upgrade to larger sensor (although few people really need that)
