a mix of marco & some other elements.
enjoy

i hv been reading up on extension tube and teleconverter.

i'm still not sure which would be suitable....
both seems to be ard the same price...

any advise?

 

[DonnyDan]

Btw i use breathing as layman term too. Does anyone the technical term for it? Because it seem that many people do not understand breathing when we ask the question and they start making fun out of it.

Btw anyone know N200 Macro need oxygen? =)

haha like this also can
heng i shoot macro using Manual focus, thus no "breathing"

As a lens barrel extends or retracts during focusing or zooming, it will draw draw in or expel air respectively. This is the 'breathing' effect that is in question.

breathe?

do u mean focus hunting?
it does hunt if u r too close to the subject, otherwise, the AF-S motor is very quiet n fast

1st time i come across the term 'breathing'...but i guess it does seem like tat...LoL

LancerEX:the vr2 mechanism "rocks"

sure it does. switch off vr & use tripod and it's back to normal shutter noise....
noise or not, still like this lense. sample pic taken with this lense, hand-held with vr on...

bokeh is still manageable

Ahhh.. I was wrong.. Google 'lens breathing' and it refers to the focal length changing when focusing. A term mainly used for cine lenses where the effect is apparent when the focus changes during filming.

In this case, IF lenses would 'breathe' more than non-IF lenses since the focusing is done in the rear elements which would in fact change the focal length slightly to accomodate the distance.

...internal focusing lense actually don't breathe, there is no air being sucked in or out of it. focusing is done by the movement of the rear elements, an integral part of the lense as a whole. hence, dust is eliminated as ambient air cannot enter into the lense. IF lenses are considered as hermetically sealed...dust free!
non-IF lenses, air is being sucked in or out as the barrel extends or retract during zooming /focusing.

There are 2 cases of 'breathing' when the term is used with respect to the lens.

One is the physical 'breathing' which is the sucking in and out of the air when the internal volume changes during zooming or focusing. This was what I originally thought it should be.

But after running the term through Google, I see more of the below being mentioned instead which has nothing to do with air.

The other more familiar term in the cine world is the focus 'breathing' where the focal length changes when the focusing is changed which is apparent in IF lenses and superzooms. This doesn't affect photography that much but those doing videos when pulling focus will be able to see this effect which changes the angle of view of the scene.

....thanks for info on 'breathing' term used in cine world.

the focal length doesn't change, what changes is the actual physical length of the len as the barrel will extend in/out during focusing.
correct me if i am wrong

...for prime lenses; the FL do not change, focusing is done by the rear elements inside the lense assembly.

...for zoom lenses; the FL changes as the barrel extends or retracts during zooming/focusing.
eg. 18-200mm zoom lense has a varying focal lengths of 18 to 200mm depending on the extension of the lense barrel.

Breathing doesnt mean the change of physical length but the change of focal length. An example is NIKON 105 AF-S it is IF, I does not extend. But while you frame your picture correctly, once u continue with focusing. The framing will change.

It is difficult for my little photography knowledge to explain. But it is best that you have a copy of it and you will get what we mean.

Btw in my knowledge 105 is not the only copy, there are quite a number of nikon lenses do breathe.

A thread of "Focus Breathing" a technical or layman term?

i'm a little confuse...BUT...enjoy ur shooting!!!

...i think the term 'breathing' doesn't apply only to one specific scenerio.....though the change of focal length applies more accurately to its meaning.

e.g. a quote from a review: "Lenses 'breathe' when focus or zoom controls are rotated and a small amount of dust is unavoidable."
...in here, 'breathing' has another scenerio application.

It is common for lenses to shorten in focal length as they focus more closely... if you look at the min focus distance of many macro lenses you will realise at max magnification the focal length is far less. One example is the 70-180mm zoom, which achieves max magnification of 1:1.3 at the "180mm" end but offers only 11cm working distance... whereas my Voigtlander "125mm" offers 1:1 magnification and almost 19cm working distance. Yes, the zoom "shortens" more

Anyway this happens to both primes and zooms... that is why some lens reviews list the effective focal length at infinity and at at min focus distance... and in-between too...

i just discovered that i have more images from this lens
will post later

 

[khock520]

...photography is fun....and very so are the layman terms used; like this one:

'mirror slapping'......actually talking abt mirror in dslr being lifted up for image to be captured by the sensor....and this may cause some camera shake....

can vr compensate this effect?

...looks like slowly; but surely the mirrorless cameras are gaining popularity....with this advantage and contrast focusing to give a sharper image; tho' slower auto-focusing.....

Back to topic. Can share more pictures from the 85/3.5 pls, Alex?

 

[maxtheevil]

nice pics that u took, outside the tests.



damn... i got to say it, i enjoy it more than the ones on the portrait sessions posted by most.
