A Quick Look on AF NIKKOR 50mm f/1.8D

Each month I will pick a SLR lens of my interest and a do a simple overview on its specifications. It can be new, old or odd whichever that I think is worth pointing out. This won’t be a full on review as I don’t have most of the them, but hopefully I can point out important little details that some might overlook.

Cheapest lens and easily consider the must-have lens, The Nikkor 50mm f1.8D is the alternate standard lens you should have on your SLR as if it is your lens cap. While a G version of the same lens (AF-S Nikkor 50mm f/1.8G) is now available, you will not get as much value out of any other lens.

Lens Overview

  • Name: AF NIKKOR 50mm f/1.8D
  • Type: Standard
  • Format: Full frame
  • Announced: 2002
  • ESP: US$134.95
It’s fast with wide maximum aperture, sharp and lightweight been the nature of prime lens.

Technical Specification

  • Focal Length: 50mm or 75 on DX camera
  • Maximum Picture Angle: 46°
  • Maximum Aperture: f1.8
  • Minimum Aperture: f22
  • Minimum Focus Distance: 0.45m
  • Maximum Reproduction Ratio: 1:6.7
75mm equivalents when used on a DX camera body, makes it a bargain portrait lens. Corner sharpness tho, is not outstanding like 50mm f1.8G or portrait lenses.

Physical Specification

  • Focus: Screw-drive, internal focusing
  • Aperture Blade: 7 straight blades
  • Dimension: 63.5 x 39mm
  • Weight: 155g
  • Material: Plastic barrel, metal mount
  • Filter Size: 52mm
Easily fits in pocket of your jacket, and dispite it’s plastic barrel it is actually very well made when compare to 18-55mm DX kit lens or Canon EF 50mm f/1.8.
This lens doesn’t comes with any accessory (unlike 35mm f1.8G DX or 50mm f1.8G), all you’ll get out of its box are: lens itself, front lens cap, plastic rare lens ‘cover’, instruction manual, plastic bags and foams. Third party lens hood and pouch can be purchased at very low price so I wasn’t worried by it at all.

A Quick Look on iPhone 4S Camera Specification

Today Apple take us to its fifth generation iPhone 4S, an incredible smart mobile device that come with more than a mobile phone. A major improvement (at least been marketed as) in iPhone 4S is upgrade to its camera component, proundly announced a 8 megapixels, “all-new optics” and f2.4 aperture.

Does it contain that much of amazing’ness, you can preview its photo quality from iPhone 4S Photo Gallery. With EXIF viewer, we can easily find out the numbers behind this brand new phone camera. Here’s a comparison with iPhone 4′s 5 megapixels phone camera.

iPhone 4 Camera Specification

  • 5.0 megapixels (2592 x 1936)
  • 1/3.2″ back-illuminated CMOS sensor (Circle Of Confusion of 0.004 mm)
  • Focal Length: 3.85mm (x7.64 crop factor, that is 30mm in 35mm equivalent)
  • Low ISO: 80
  • Maximum Aperture: f/2.8
  • Maximum Shutter Speed: 1/1000 second or faster

iPhone 4S Camera Specification

  • 8.0 megapixels (3264 x 2448)
  • 1/3.2″ back-illuminated CMOS sensor (Circle Of Confusion of 0.004 mm)
  • Focal Length: 4.3mm (x8.2 crop factor, that is 35mm in 35mm format equiv.)
  • Low ISO: 64
  • Maximum Aperture: f/2.4
  • Maximum Shutter Speed: approx. 1/2000 second
It remains to be a relative small image sensor, much smaller compared to a compact camera. Even at f2.4, you will have difficult time to try to produce subject isolation (aka/ “background blur”) like Apple illustrated in its photo gallery.

A Quick Look on AF-S DX Zoom-NIKKOR 18-70mm f/3.5-4.5G IF-ED

Every month I will pick a SLR lens of my interest and a do a simple overview on its specifications. It can be new, old or odd whichever that I think is worth pointing out. This won’t be a full on review as I don’t have most of the them, but hopefully I can point out important little details that some might overlook.

Something I would consider as luxury kit lens. This is a very reliable entry level wide angle lens and is definitely not built to be cheap (in terms of quality). When side with AF-S DX 18-55mm f/3.5-5.6G you can feel the different in weight and built quality and lack of distance meter on 18-55mm may feel a bit awkward when shooting landscapes.

Lens Overview

  • Name: AF-S DX Zoom-NIKKOR 18-70mm f/3.5-4.5G IF-ED
  • Type: Standard Zoom
  • Format: For Cropped (DX) Sensor, or FX in DX mode.
  • Announced: 2004
  • ESP: US$459.95
Its ESP is about double the cost of more common18-55mm, however since this is a kit lens you will be able to find one floating around in second hands market cheap.

Technical Specification

  • Focal Length (35mm equivalent): 27-105mm
  • Maximum Picture Angle: 76°
  • Maximum Aperture: f3.5
  • Minimum Aperture: f22
  • Minimum Focus Distance: 0.38m
  • Maximum Reproduction Ratio: 1:6.25
Ability to achieve f3.5 at 18mm and f4.5 at 70mm is pretty impressive and plenty of light consider it is an entry level lens.

Physical Specification

  • Focus: Ultrasonic-type (SWM), internal focusing
  • Zoom: Rotary, extends when zooming
  • Aperture Blade: 7 rounded blades
  • Dimension: 73 x 76mm
  • Weight: 420g
  • Material: Plastic barrel, metal mount
  • Filter Size: 67mm

3 dispersion element, 7 rounded aperture blade, SWM, internal focusing.. lot of feature stuffed in, however most people will felt seamless about them. One physics that will standard out in time is the filter thread size. At 67mm, many will have their grunge toward Nikon as the filters they buy for this lens and can hardly share with other lenses.

A Quick Look on Nikon AF-S Micro Nikkor 40mm f2.8G DX Lens

Introduction

This is a suprise for many, but on July 2011 Nikon has annoced the addition of cheapest macro-photogrpahy lens (where Nikon calls them ‘Micro’) into its lineup.

It is a DX lens with an usual focal length of 40mm (which is approximate equivalent to a 60mm lens used on a 35mm format camera).

When comparing with its closest sibling Nikon AF-S 35mm f1.8G, there are obvious advantages and disadvantages between both lenses making them both unique and desirable for variety of scenarios. For example, 40mm f2.8 is designed with close range focusing for creating super sharp image quality with short focal distance, meanwhile 35mm f1.8 has an aspherical glass for reducing distortion and chromatic aberrations when shooting at standard and long distance.

The lens is not yet avaialble to date and is current scheduled to be available in late August 2011, ESP US$279.95

In summary, there are couple of advantages you may appreciate:

  • Sharpest entry level lens you can find.
  • Cheapest 1 to 1 image reproduction ratio lens, where its 85mm DX equivalent costs almost twice as much.
  • A decent focal length for portrait and everyday photography.
  • Ideal for photographing floral, food, pet and coin size objects.
  • Standard 52mm filter size that you may appreciate more as your lens collection grows.
  • You get the lots in the box: front, back lens caps, lens hood and pouch are all included.

And on the other side of the coin, you may want to known the following possible downsides:

  • This lens is not ideal for photographing very small objects (such as insects) where lighting condition gets too difficult, which is what you’ll want to use your macro lens for.
  • 40mm f2.8 macro is sitting on a very uncomfortable zone for experienced users: bit too long as standard lens, bit too short as macro lens and bit too dark as prime lens.

  • Focal Length: 40mm fixed
  • Minimum Aperture: f2.8
  • Maximum Aperture: f22
  • Vibration Reduction: No
  • Minimum Focal Distance: 0.16m
  • Maximum Reproduction Ratio: 1:1
