    I don't have a FF DSLR to hand and don't fancy trying it on film but have had a go with my 90mm on a Canon 7D.....should be a bit less forgiving than using it on FF but never mind

    1/8th of a second at f/16, no IS available:

    Bit ropey up close but diffraction probably isn't helping either.....couldn't be bothered waiting for it to get darker so I could get a slower shutter speed at f/5.6 or setting the tripod up for a control shot

    1/125th on FF and a distant subject isn't exactly much of a challenge

    Yeah ... the point here is that the smear does not look quite symmetrical, diffraction or a focusing error would, so we're left with a lens aberration (decentering fault if at the centre of the frame) or camera shake. Guess which I think is more likely. But taking a control shot with the camera properly supported, or hand held with a much faster shutter speed, or using electronic flash (the built in unit would do well enough gfor this purpose) would prove the point.

    It's funny how we're prepared to spend shedloads of money on a lens which has marginally less aberration than a cheaper one and then throw away the performance advantage by poor technique.

    1/100th at f/5.6 on a different bit of the wall was much sharper FWIW....and if it was that ropey at f/16 I wouldn't be happy using it at f/25 for pics of mushrooms and stuff

    Maybe this is a better example....

    1/10th at f/16:

    I believe that one's personal condition matters greatly, and this can change very rapidly with previous exertion. Also medication such as beta blockers may help. How many of us have slowly deteriorated with age then suddenly improved after a heart event and got onto beta blockers?

    I know my ability to hold a camera steady varies greatly depending on how hungry I am. I don't do macro before breakfast

    And funnily enough I shot the brick wall before breakfast but then shot the bushes by the garages after a large quarter pounder with cheese meal. £4.49 for steadier hands?...bargain

    It was always said that you gain about 3 stops using a rangefinder rather than an SLR. That's about the difference I get with Vibration Reduction.

    Nah ... there's no kick from the mirror movement but the shutter reaction is much the same, perhaps rather more in a rangefinder than in a SLR because of the lighter weight. But the big difference is that rangefinder users are almost always using shorter focal lengths.

    Even so, one stop I'd accept, but three is ridiculous.

    I can only talk about my own experience with a Leica M6 compared with Nikon SLRs. I definitely achieved 3 stops difference, but I was very used to both types of cameras, and it was not dependent upon the focal length of the lenses - always like for like.

    About 1/4 sec on my bronica with a 105mm on the front

    Does it hold up to peer review though?
