The Nikkor 10.5 Fisheye Lens for Nikon DX Camera Users

sigma lens


The Nikkor 10.5 Fisheye Lens is designed for Nikon's DX lineup of Digital SLR's with the1.5x crop sensors. This lens is a 180 degree "full frame" diagonal fisheye. No circular images with this lens. FX users can also use this lens, but in order to take full advantage of these cameras full frame sensors your better off going with the Nikkor 16mm f/2.8 Fisheye instead.

If your a Nikon DX user and your looking for a fisheye lens that delivers sharp, crisp images with beautiful saturation and standout contrast then you need look no further than the Nikkor 10.5mm f/2.8 Fisheye Lens.

Since it first came out in 2003 this lens has been a hit with Nikon users who love shooting wide angle. The Nikkor 10.5 fisheye has even managed to generate a cult following among skateboard shooters who love being right in the center of the action.

Features of the Nikkor 10.5 Fisheye Lens

With a maximum aperture of f/2.8 the Nikkor 10.5 is a fast lens allowing the photographer to shoot in low light conditions. You can safely shoot at 1/10th of second without using a tripod with this lens providing you have a steady hand. Great for those who love to shoot in low light conditions! The minimum aperture of the Nikkor is f/22.

With a Close Focus Range of 5.5 inches - 1.25 inches from the front of the lens - you can move in very close with the Nikkor 10.5mm Fisheye with very accurate focusing thanks to Nikons special CRC (Close Range Correction) focusing technology. One thing to keep in mind when using this lens is that you don't get too close with it and scratch the lens! This is very easy to do with a fisheye lens since objects appear farther away than they actually are. As with any fisheye lens you can't use protective filters because there are no threads on the front of the lens.

Like other high quality fisheyes, the Nikkor is set up to use rear gel filters for those who like the option of shooting with filters when the need arises.

At only 2.5 inches long and 2.5 inches in diameter, the Nikkor 10.5mm is a very light weight and compact lens weighing in at a mere 10.7 ounces. Constructed with10 lens elements in 7 groups this little Nikkor is a tough lens.

AutoFocus on the Nikkor 10.5 Fisheye

There's good news and bad news here. Auto Focus is very fast on this lens as long as your using a Nikon that has the built-in focus motor. If your using Nikons like the D40/D40x or D60, then your out of luck since the Nikkor 10.5mm itself has no built-in focus motor. This doesn't bother many Nikon users since this lens is in focus most of the time anyways because of its small focal length and the extreme depth of field you always get with a fisheye lens.

For those who insist on having Auto focus many Nikon DX users have turned to the Sigma 10mm f/2.8 Fisheye lens for Nikon which does have a built-in HSM focus motor.

All in all, the Nikkor 10.5 fisheye lens is a winner and you won't be disappointed with it unless having AF is essential for you and if you fall into the category of Nikon users who don't have built-in auto focus motors with their digital cameras.

New Sigma APO 50-500mm F4.5-6.3 DG OS HSM. This is a 10x high zoom ratio ultra telephoto zoom lens incorporating Sigma's original Optical Stabilizer function. This lens covers a wide range of focal lengths from 50mm to 500mm ultra telephoto. The OS (Optical Stabilizer) function offers the use of shutter speeds approximately 4 stops slower than would otherwise be possible. For Sony and Pentax mount, the built-in OS function of this lens can be used even if the camera body is equipped with an image sensor shift anti-shake system. As compensation for camera shake is visible in the view finder, the photographer can easily check for accurate focus and ensure there is no subject movement. Four SLD (Special Low Dispersion) glass elements provide excellent correction of color aberration. The Super Multi-Layer Coating reduces flare and ghost and ensures high image quality throughout the entire zoom range. This lens has a maximum magnification ratio of 1:3.1 (at the focal length of 200mm) making it ideal for close-up photography. This lens incorporates HSM (Hyper Sonic Motor), ensuring quiet and high speed AF as well as full-time manual focus capability. The addition of the optional 1.4x EX DG or 2x EX DG APO Tele Converters produce a 70-700mm F6.3-8 or a 100-1000mm F9-12.6 MF zoom lens respectively. This lens is equipped with a Petal-type hood to block out extraneous light. The filter size of this lens is 95mm and the lens is supplied with

Camera Tutorial 04: Lenses

In this episode of "Learn to Speak Camera", I give a brief overview of the main types of lenses which most consumer and professional cameras can use. Since compact and bridge cameras are stuck with the lenses they have, some of this does not apply to them. However if you own a compact or bridge camera you may find it informative to learn what you could have access to. I would recommend hiring a DSLR body and a couple of different kinds of lens if you want to get practical experience of the differences. The errata for this episode are posted here: www.facebook.com The properties of lenses are important and intricate topics, which will be visited over the next episodes: Focal Length in episode 5, and Aperture in episode 7. The related topics of Crop Factor, Shutter Speed, and Autofocus will appear in episodes 6, 8 and 14 respectively. Sorry about the jaundiced look - lighting problems! I get this fixed by episode 7.

Digital Photography Tutorial - Digital Camera Filters


Image : http://www.flickr.com


Filters are plastic or glass layers placed in front of the lens of a camera to block certain light waves to reach the sensor. Although most filters are designed for DSLR lenses, generic filters can also be purchased and used together with compact digital cameras.

There are many filters out there but I am going to talk about three of the most useful types.

The first one is called the UV filter. UV stands for ultraviolet and it is the electromagnetic rays that can damage your skin and your camera sensor. If most of your photography activities are indoors then this filter may not be useful for you. But it is extremely necessary for outdoors. This filter not only protects the sensor from ultraviolet rays but it also physically protects the front of the lens. This is one of the most generic and cheapest filter but highly essential.

The second one is called the CP-L filter. This filter is actually a polarizer. The filter has a polarizer that can be rotated on a thin surface. This filter allows photographers to adjust certain light rays to pass through the lens and onto the sensor. This filter is handy to minimize reflections from a subject. For example, when shooting a lake, a polarizer may be used to reduce the reflection of the lake, enabling the camera to visibly see the fishes swimming in the lake.

The third one is called ND Grad. Filter. This is an acronym for Neutral Density Graduation filter. Unlike the previous two filters, this filter is separated into two separate regions. The filter is separated into half and one region is darker than the other. The dark region gradually becomes light as it approaches the other half. This filter is useful for landscape photography when the sky is usually overexposed to compensate the exposure of the land. This filter is use to darken the sky and balances the exposure stops between the sky and the land to produce an equally exposed subject. With this filter, the brightness range of the composure is also reduced thus solving the subject-brightness range problem in cameras

There are a few classifications for this filter. There are usually two values of an ND Grad. Filter: 0.3 and 0.6. The 0.3 filters are used for 1 stop compensation where as the 0.6 filters are used for 2 stops compensation. (Each stop is the stop difference between the sky and the land) For each value, there's soft and hard graduation from the dark region to the light region

All lens filters are also categorized with their diameter. That is all about filters now. If you have some money to spare, get a filter today and try it out! There are lots of potentials in photography when using a filter. Ask your local store for some recommendations as well.

This is a great lens for someone starting to build a lens collection. I have had great luck photographing lilies as well as portraits. Macro option makes it a great alternative to a standard lens.

Lens is lightweight but still has good construction.

Macro option can only be turned on at 90 mm this was a little confusing at first.

Great pictures great price.
