I was just checking my cameras to see if had them all up to date with firmware. I noticed this on the Nikon website................ The following products do not have ANY firmware updates. D2Xs, D50, D60, D70s, D90, D3000, D5000, D5200 |

Looks like they do get it right the first time - sometimes. Terry |

not with the 7100 update after running round like a headless chicken all week and not finding the answer to soft pics on the d7100 a post on flickr from a contact made me realise this is not a ordinary camera with a normal sensor ,he disected one of my pics from yesterday and told me that my shutter speed was way to low for b.i.f ,,i was working on my old formula of focal length plus crop factor equals shutter speed ,i put in a minimum s/s of 1/1600th sec and auto iso 100-4000 and let rip in late evening light .BINGO the first SET of sharp b.i.f shots i have got with the camera .this one below is taken with the 300mm f4 and 1.4 tc ,i will try the new formula on the 1.7 tc tomorrow .PHEW WHAT A RELIEF thats saved a few bob on e/bay fees  test 3 by blackfox wildlife & nature imaging, on Flickr this btw is a huge crop as well so even better |

JK, re: I noticed this If I remember correctly, Nikon (in dutch language) even maintain a page to confirm what products can do without (in their opinion) Regards, Gilbert In english this is https://nikoneurope-en.custhelp.com/app/answers/detail/a_id/19609/related/1 |

So for my D3 I get away with my 300mm by going as slow as 1/200th second. On the D800 even at 1/500th I can see the evidence of shake unless I put the camera on a tripod or monopod. |

It depends on the pixel dimensions. A large pixel will allow shake with an edge line of detail to move within it's boundaries without showing any blur. If you reduce the pixel size by half, i.e. Double the linear count that will mean you either have to reduce the shake by 50% or double the shutter speed. This isn't allowing for variations in inter pixel space, which may also affect the effect of camera shake. Roll on the digital 10" X 8" full frame digital back with 12 MegPixels!!! That should eliminate camera shake. If you can lift it of course... |

the problem that now arises is ,i know the cause ,i know the effect ,either a high shutter speed and/or VR is needed ,a large heavy expensive lens is out of the question ,is this the reason that nikon have brought out the new 80-400vr and is rumored to be bringing out a new 300mmf4 VR . i for one am not sure whether the higher shutter speed limitations is going to be any use come the winter ,especially given my northerly locale .its a real quandary d300s super camera limited by iso range ,d7100 limited by high shutter speed . anyone got any knitting needles for sale >:(>:( |

The better crop potential of the extra pixels may also obviate the necessity for the TC, which would gain you another stop. Dont despair Jeff...it will probably snow all winter up there and that will kick some light back onto the bif. |

luckily its a nikon so while you can see the noise in a raw file its easily removed with decent software ,had a little play today (the suns only just come out at 4p.m ) and it looks like the 1.7tc shares the same shutter speed sweet spot of 1/1600th sec. thought i might have to move that one on.i could kick myself really for not realising this earlier but its such a basic problem it passes you by ,and its not showing at shorter focal lengths either .which obviously dulls your response to the real answer. thinking about it now i know the answer its simple really the sensors are made/developed by sony ,ALL there camera bodies have built in image stabilisers as well ,plus most of there latest bodies incorporating these sensors also have mirror less built in as well ,negating any camera shake problems  |
