Predictions > nikon D400


Everybody asking me about , what will happen when the new D400 released. Nothing. As nothing happened they released D200 over D100 and D300 over D200. At the moment, a lot of D200 users are not able to buy a new D300 and waiting for the price drop down and second hand market.

Going back to D400, here are what will you face (more or less)

D400 will be FX format with a FX sensor inside. DX lenses will be recognized automatically.

5 fps at FX, 6,5 fps at DX format.

16 MP in FX, 6.9MP at DX format.

A new LCD, with 3,5" two fingered touch screen (wow)

1080p HD video is also possible.

Possible release will be May 2009

Extreme predictions : May have a GPS and wireless system onboard

Expected price tag will be around 2500US$/Euro

Buying a second hand nikon ?

If you are buying a second hand lens for your nikon - nikonos - nikkormat camera and not sure about its orginality, you may take a look below website for all original serial number lists :

Lens Review - Nikon AF Nikkor 180mm f/2.8D IF-ED

nikon nikkor AF 180 mm f/2.8D IF-ED (1994 Release)


Focal Length : This is a FX format lens, so you can both use them on typical SLR 35 mm cameras and D-SLRs. But on a D-SLR camera, it will effect like 270 mm.
Aperture: f/2.8 . Nine-bladed rounded diaphragm stopping down to f/22
Optics: 8 elements in 6 groups. 1 ED glass element.
Closest Focus: 1.5 m(5 feet)
Macro Ratio: 1:6.6
Filter size: 72mm Non-rotating, Internal Focusing
Accesories: Lens rear/front caps, Barrel shaped, Bayonet Lens Hood . Lether Lens (CL38S)case is included.
Dimensions: 79 mm diameter. Length is 144 mm.
Weight: 760 grams

The Nikkor 180mm f/2.8D is extereme sharp with showing NO flaws. Build quality is excellent. Lens glass quality is very high. According to IMATEST results, pinchusion distortion is only 0,3% , not negligible in field conditions. Vignetting is almost non-exsist. You may shoot without worrying even at widest aperture setting of f/2.8. MTF Resolution results are excellent starting from f/2.8 reachest peak values at f/5.6. Chromatic Aberrations are not field relevant. (limit is 1 pixel, test results do not exceed 0,64 pixel)

180mm f/2.8D is a very good lens for outdoor portraits and wildlife photography. Some may consider to buy a 70-200mm f/2.8 VR or 80-200mm f/2.8 instead when price is considered. But the weight is an advantage for this lens for hendheld shoots.
- Not so fast Auto Focus (but not slow for sure!)

- Be careful about second hands. There is no lens in the back side of the lens to protect the diaphragm blades. They may be filthy !!

VERDICT : It is not a cheap lens. I may recommend 80-200mm f/2.8 instead if you are not a prime lens addictited. All test result are almost excellent. It is compact telephoto lens with good performance. Recommended (8/10)

What does PC-Nikkor means ?

PC-Nikkor means a lense which features a Perspective Control ability, to be more clear, they are wide-angle lenses with extended film plane covering ability. These lenses are used to cover large rectangular subjects, for i.e., a tall building, the photographer has to tilt his camera upwards to include the top of the structure; generally, the resulting image portrays in the photograph will have walls of the building appear to converge, as if the building were falling over backwards. With the PC Nikkor lenses, you may correct this convergness.

Technically, there is an other trick to minimize effect of converging perspectives.By using a wideangle lense, you shoot the subject in the middle but you have to compromise with a loss of useful negative space with inclusion of large unwanted foreground in the photo while cropping to eliminate undesirable elements in a wide-angle negative. With the new D-SLR crop factor 1,5x cameras, you will have less problem.

nikon D90 D-SLR > Is it a speculation or truth?

Altough a a lot of bloggers consider this is a big baloon, i will use my sixth sense and share my prediction:
First of all , nikon's tradition will change about two digit models use CCD sensors. As you all know, D40, D40x, D50, D60, D70, D70s, D80 uses CCD sensors.
D90 will have a new developed Sony CMOS sensor, with 12.3 MP. Speed will be 3-3.5 fps different from D300. This will be an answer to Canon 450D for sure.
