D5D vs D7D in term of AF speed and Image Quality

[Stepney]

Hi everyone,

I am considering upgrading from my beloved A1 to D5D or D7D, so that I can make use of my Minolta AF mount lenses. Well, actually just feeling itchy...

I prefer lighter camera for travel purpose. So, D5D is clearly a choice. But concerned with the AF speed/accuracy and the image quality of the 2 camera.

For the AF speed/accuracy, i am expecting significant improvement from my A1. Between the D5D/D7D, If you have chance to play with both camera in low light condition, using the same lens, would you observe any difference?

For the Image quality, I notice that D5D uses primary color filter and D7D uses RGB filter. No idea what it means, but surely the design is different. Which camera will produce "cleaner" (noise free) images, the ASA 100 to 400 range?

Thanks for your feedback...

I have used both A1 and 5d. AF with good lense (28-70 2.8, 80-200 apo G<-- of cos la) is really fast, instant, limited only by the speed that the lense/AF motor in the body can phycsically move the focusing ring.

Images useable out of the cam up to iso 1600. And with PP at 3200. some sample from night safari here:manual focus 150mm, 1/10s shutter, iso3200... uh its almost pitch black over there. its the 80-200apoG.



another one. this one AF iso 3200 1/100 or so shutter. 200mm AS is great



both pics went thru noise ninja.

On tripod or hand held?
Great shot.. great camera.

hi
compared to my dynax 5 film, the same lens on D5D seems a little bit faster, AF accuracy seems to be the same. (all this based on "feeling" only, no scientific data to back me up ). the kit lens with D5D is quite fast though.

i thought primary colours means RGB ?

HAND HELD!! isnt AS wonderful 1 shot nice out of about 8... i think weight lifting and being quite heavy (87kg hehe see my avatar...) helps holding that lense steady though... its uh quite... hefty! but with pics like that i will never complain!! I also was plesantly shocked when i saw this pic on my LCD... this is probably the most challenging lighting anywhere and they are very strict on the "no flash" rule at night safari.

Stepney, its this kind of shot that the A1 got no chance to get.

yeap.. AS is wonderful..
BTW, I'm surprise on how clean your photo is at ISO3200.. is noise ninja SW that GOOD in eliminating noise at high ISO?

yes it is good im no NN expet i jus try several settings (there are many degres of noise reduction/sharpening) till i find one thats good, its diff for diff types of pics. but of cos iso3200 is actaully quite good for the 5d! the pic was impressive at full screen size even before PP. Its only when u view a crop then its of cos noisy...

I actually have a profile for the KM 5D (not done by me)... maybe I should upload it to the NN support site?
