Sigma 15-30mm f/3.5-4.5 EX DG IF Aspherical Ultra Wide Angle Zoom Lens for Nikon SLR Cameras

Sigma Photo introduces the Sigma 15-30mm f3.5-4.5 EX Aspherical DG DF for Nikon SLR cameras and is the first to open a new range of photographic possibilities. Using a hybrid aspherical lens in the front lens group to minimize distortion and astigmatism, and molded glass aspherical lens in the rear lens group to minimize spherical aberration, ultra-wide-angle photos appear more natural than ever. Filter size – Rear (gelatin filter insert type) – Does not use any front, screw-in filters Lens construction – 17 elements in 13 groups Maximum aperture – F3.5-4.5 Minimum aperture – F22-32 Dimensions – 3.42 Diameter x 5.12 Long Includes protective case

This lens is very sharp especially at 15mm f8-16 which is the aperture we use for landscape. It can be used on 35mm film and it will be really really wide at 15mm. It can also be used with digital camera. I used with D70 and love it. It is much sharper than sigma 12-24 if you check the mtf chart at sigma web site.
It is my favorite lens.

Kenko 2x Teleconverter MC4 DG for Nikon AF D300 D200 D80 D50 D40 D40x D70 D70s D100 D2x D2Xs D1X D2H D1 F100 F6 N65 N75 N80 N90 Camera

From Kenko

The Kenko Teleplus MC4 DG 2x Conversion Lens will multiply the focal length of the existing lens by 2x, and will cut back the amount of light by 2 f/stops. For example, using a 2x teleconverter with a 300mm lens will effectively increase the focal length to 600mm. A lens set to f/2.8 will now be f/5.6. Teleconverters are not recommended for lenses wider than 50mm, e.g. 28-105mm. However, full AF operation is only possible with lenses with open aperture of f/2.8 or brighter. Please be aware that AF will work properly only if there is enough light and contrast on the subject to activate the camera’s AF sensors. Manual focusing is recommended when using lenses with smaller open f-stop value than those given above.

At first, I had reservations about buying this item. I own a Nikon D80 and planned on using it with my Nikon 180mm f2.8 D lens. Since Nikon doesn’t make a teleconverter for the 180mm, I went ahead and bought it.

First off, I’m thrilled with the results. This item really delivers. Not only does it work flawlessly with the lens and camera, but it also produces sharp images. I like it so much I sold my 300mm f4 Sigma lens on ebay. This teleconverter gives me the equivalent of a 360mm f5.6, at about half the weight.

I can’t stress enough how happy I am with this teleconverter. Bravo!

Sigma 105mm f/2.8 EX DG Medium Telephoto Macro Lens for Canon SLR Cameras

The Sigma 105mm f2.8 EX Macro delivers superb, distortion-free images throughout its broad focus range, from infinity telephoto to 1: 1 (life-size) macro, as close as 12.3″ without accessories. Its non-rotating front lens group makes it easier to work with polarizing filters and has a focus limiter (eg. Full Range; – 15.8 in.; 14.6 in. – 12.3 in.). A “focus-free” mechanical design allows the lens to auto focus without any interference from the manual focus ring. This makes it easier to hold the lens without affecting the speed or normal operation of the autofocus function. Rugged mechanical construction also makes it durable enough for even the heaviest use required by professional photographers. The Sigma 105mm f2.8 EX Macro features the new deluxe external EX finish. These features and other Sigma optical advances, including an uncommonly broad range of focus, make this an ideal lens for a wide variety of applications, from nature photography to portraits. A handy screw-in type metal sunshade makes it easier to rotate a polarizing filter.

I have employed my Rebel XT digital SLR into my dental office. I upgraded to the Rebel XTi (10 mpixels) for home. I purchased the Sigma ring flash with a Sigma macro lens for the Canon SLR family. If you look at the Lester Dine website this is basically what they sell for a few hundreds dollars more.

I compared the ring flash and lens with the ones offered by Canon and felt that it was worth saving $300 by purchasing the Sigma combo.

The macro lens/ring flash work well for dental purposes. After a little experimentation I discovered that I get the best images by using the aperature priority setting. All settings are used with ISO 400 speed. I set the aperature at 14-16 for intraoral shots. This gives the best depth of field. I also use the operatory light for intraoral shots. I set the aperature to 6 for full face shots.

I use autofocus but set the ratio to 1:2 to 1:3 for intraoral shots. This keeps the autofocus from “hunting”. I frame the shot by moving towards the subject. Once I get close to the image that I like I use the autofocus to get the final focus for the picture.

Sigma AF 18-200mm f/3.5-6.3 DC OS (Optical Stabilizer) Zoom Lens for Canon Digital SLR Cameras

This 18-200mm f/3.5-6.3 DC OS (Optical Stabilizer) high power zoom ratio lens is exclusively designed for digital SLR cameras and is capable of covering a wide range of focal lengths from wide angle to telephoto. It is equipped with Sigma’s own unique technology of OS (Optical Stabilizer) function. This function uses two sensors inside the lens to detect vertical and horizontal movement of the camera and works by moving an optical image stabilizing lens group, to effectively compensate for camera shake. It automatically detects movement of the camera and compensates for camera shake when shooting moving subject such as motor sports. Two SLD (Special Low Dispersion) glass elements and three aspherical lenses provide excellent correction for all types of aberrations. The super multi-layer lens coating reduces flare and ghost. This lens provides superior image quality throughout the entire zoom range. An inner focusing system eliminates front lens rotation, making the lens particularly suitable for using circular polarizing filters and the petal-type lens hood supplied

The Sigma 18-200mm high-zoom-ratio lens is designed exclusively for Canon digital SLR cameras and is capable of covering a wide range of focal lengths, from wide-angle to telephoto. Two Special Low Dispersion (SLD) glass elements and two hybrid aspherical lenses correct for all types of aberrations, letting Sigma house the extended-range super-zoom lens in a compact and lightweight body that measures 70mm in diameter and 78.1mm long and weighs a mere 14.3 ounces. The new lens coating, meanwhile, reduces flare and ghost–a common problem shared by many digital cameras–while also creating an optimum color balance. Other details include a minimum focusing distance of 45cm (17.7) at all focal lengths, a high zoom ratio of 11:1, and a maximum magnification of 1:4.4.

The lens design incorporates an inner focusing system that prevents the front of the lens from rotating, making it particularly suitable for using circular polarizing filters and petal-shaped lens hoods. In addition, the overall length of the lens never changes during focusing, making the lens convenient to handle and easy to use. Finally, the lens’s zoom lock switch eliminates “zoom creep” during transport–a convenient addition when traveling. The lens, which includes a metal mount, is backed by a one-year warranty.

This lens is phenomenal. It is the perfect walk-around lens. 28-300mm lenses don’t compete, as I find the 18-28mm range to be far more useful than the 200-300mm range for APS-C sensor cameras like the Rebel and 40D. Sigma has an 18-250mm lens, but its lack of image stabilization is a deal-breaker. This lens isn’t too heavy, isn’t too large, and it zooms like a bastard. If I had to have one lens for an APS-C sensor camera, with cost as no object, this would be it. Second would be Canon’s 10-22mm. I would pay big bucks for a faster version of this lens.

Sigma 10-20mm f/4-5.6 EX DC HSM Lens for Nikon Digital SLR Cameras

From Sigma Corporation

10-20mm F4-5.6 EX DC HSM lens allows enjoyment of super wide-angle photography and it is a very powerful tool for indoor shooting and landscape photography with digital SLR cameras. Wide angle of view (102.4 degrees at 10mm and 63.8 degrees at 20mm) offers the photographer greater freedom of expression. 3 Special Low Dispersion (SLD) glass elements are employed for effective compensation of color aberration, which is a common problem with super-wide angle lenses. One piece of glass mold and two hybrid aspherical lenses, offer excellent correction for distortion, as well as all types of aberration. This lens is equipped with an inner focusing system, and the models which are equipped with HSM system provide quiet, high speed autofocus shooting and also offer full time manual focusing. It has a minimum focusing distance of 24cm at all focal lengths. The non-rotating lens barrel perfectly suits the petal shaped lens hood. A circular polarizing filter can also be used conveniently. Angle of View – 102.4 – 63.8 degrees 6 Diaphragm Blades Minimum Aperture F22 Minimum Focusing Distance – 24cm/9.4 inches Maximum Magnification – 1 – 6.7 Filter Size – Diameter 77mm Lens Hood Petal Hood Dimensions – Diameter 83.5mm x Length 81mm, 3.3 x 3.2 inches Weight – 470 gram (16.6 ounces)

Pros: Extremely wide angle, you’ll wonder how you got along without it.
Also, it comes with a sleek case, if thats something that matters to you.
Cheap for a wide angle.

Cons: A Crapload of distortion, especially at(but not exclusive to)10mm.
Cheap for a wide angle. (No, this isnt a typo )

Having said that, once you get past the wild distortion at the wide end, this is a truely unique lens, that fulfills a very useful purpose on the Nikon dlsr.

Once you shoot the world at 10mm (15mm film terms), rarely will you want to go back, believe me, this is one incredible lens, once you’re past its shortcomings of distortion. Being the widest angle zoom for a nikon Dslr, Im sure you will not be disappointed, especially not for the price.

This is a tremendously useful lens offering from sigma. It competes well with the other wide angle lenses you can currently buy for a Nikon digital body, with one exception; the distortion, if you have any qualms with wide angle distortion, or have a habit of fixing distortion in photoshop, this will probably be one of the worst lens choices you can make, but, with all things considered, Im glad I bought this lens, because the pictures Ive captured with it, are not possible on any digital equipment, save for the D3.
