Focus Test with my D7000 :



result : Front focus problem ?

test few times and results is the same.. anyone having focus problem with Nikon D7000 ?
tested with AF-S 50mm f/1.8G

focused on the middle broad black line using AF-S, single point middle(center of 9 points).
heard a lot of people having back focus issues.. but this one is having front focus.. maybe because of the lens itself (50mm 1.8G), should try with kit lens too.

thank you for your feedback.. will post the result here again soon..

^can get sb700 at foto selangor at RM980
dry box chepest (Karakka) is around RM130
and definetly can get camera bag at RM300.

so answer is yes..

EDIT : also, price for SB900 dropped to RM1400.. at Foto Selangor of course.

18-200mm obviously has long reach.. its a great lens since it covers a lot of focal length.
has metal mount, more barrel distortions and less sharp than 18-105mm.. front lens also rotates and needs 77mm filter(AFAIK)

18-105mm is a kitlens has high MTF consistently except until at the long end(105mm). plastic mount and need 67mm(great if you're gonna buy the Tammy 17-50mm f2.8 in your next lens purchase) ..

So, if you're going for picture sharpness, details.. get 18-105 or better get the superior 16-85mm.. but if you want to have all in one lens, get the 18-200mm since its gives you more convenient.. no need to change lens for tele..

Mostly people would suggest you to get 18-200mm

^err, vignetting ? the rest, I dont know..

Encountered a problem here. Hope you guys can help.

So I take a few shots with the 50mm f/1.8G lens with AF-S and single focus point. When I just half press the shutter button, it will focus lock and press the button all down it will take the shot. The static object is in focus with aperture f/1.8 and shutter speed of 1/250 & even 1/30 if its in the middle without the need to recompose.

The problem is that the static object is somewhat blurry when I recompose with the 'half shutter button pressed' and even by using the 'AE-L, AF-L button'. The same shot was taken with 1/250 and 1/30 at aperture f/1.8. FYI the 'blurry rate' of the two shutter speed is very similar.

I did learned that to get non blur shot is with shutter speed of 1/X where X is the focal length(with DX format times it with 1.5). In this case, not less than 1/75 ?

In short explanation( direct shot-->focus, composed shot-->blurry)

If put aside the handshake problem, what other things could cause this blur result?

Thanks.

nice found! Thanks m8
