Canon EOS Rebel 550D/T2i announced! First impressions

Tuesday, February 9th, 2010

Canon updated the mid-range section of the DSLR cameras with the new Canon EOS Rebel T2i/550D.
Building on the popularity of the EOS 500D, the EOS 550D is designed to give you more access to video as well as Eye-Fi compatibility. Priced at US $ 899.99 with the standard 18-55mm f/3.5-5.6 IS lens, the EOS 550D will be available from the 24th February onwards.

There are a few basic upgrades on the Canon EOS Rebel T2i/550D. Notably is the ISO sensitivity top limit being raised to ISO6400 although you can still expand that to ISO12800 if you wish. An interesting point on this is that you can now cap the highest ISO point while in AutoISO, so it won’t use ultra high settings to get a decent shutter speed.

The new screen resolution should help with the new video functions of the Canon EOS Rebel T2i/550D. It has a Full HD recording facility of 1080p with manual control as well as selectable frame rates. You can choose from 30, 25 and 24fps at full HD quality while pushing it up to 60 or 50fps will reduce the quality to 720p. Alternatively, putting the camera in program mode means you don’t have to worry about it. There’s also a Movie Crop function that reduces the resolution to a 640×480 area but means you get a magnification of 7x the focal length of the lens.

The metering system now matches the one found on the popular Canon EOS 7D using the new iFCL metering with 63-zone dual-layer sensor. IFCL stands for intelligent Focus, Colour and Luminance metering and it’s this information that the new system uses to meter with. It works in conjunction with the focus points to determine the distance from relative subjects and weights the exposure according to the algorithm results.

Order now, the Canon EOS Rebel T2i/550D is priced at $799.99.

Panasonic Lumix GF1: micro gear, great photographic power!

Sunday, January 24th, 2010

The Panasonic Lumix DMC-GF1 is the lastest member of the Micro Four Thirds family. But before Micro Four Thirds, there was Four Thirds. With Olympus having produced relatively small film SLRs since at least the early 1970s, it was probably no surprise that they would partner with Kodak to introduce the Four Thirds System standard (with its sub APS-C sized sensor) as they prepared to move into the digital age. The smaller sensor helped the company produce diminutive DSLRs that carried on the Olympus tradition.

Sensor resolution is 12.1 megapixels and there are full manual and auto controls, plus a palette of user-established settings that rival DSLRs in number and scope. You can shoot in RAW if you choose, or RAW/JPEG combinations, and there’s 1280×720 HD video in AVCHD Lite (which is more memory efficient than Motion JPEG) or Motion JPEG formats.

The GF1 is undoubtedly smaller than its big brothers, the G1 and GH1, but it’s not quite as tiny as Panasonic might lead you to believe. Measuring 119 x 71 x 36.3mm and weighing 285g without a lens attached, it’s just a little smaller and 50g lighter than the very similar Olympus E-P1 camera. Instead of a traditional DSLR hand-grip, the DMC-GF1 has a slightly raised vertical area on the front-right which isn’t big or pronounced enough to be of much assistance. The rubberized thumb-rest on the rear is a lot more useful.

Because of space considerations inherent in the Micro Four Thirds System, a 3.0 inch LCD monitor operating in Live View is the only means of image composition and framing for capture.

If you don’t want to use the LCD screen for composition, an optional electronic external viewfinder is also available, the Panasonic DMW-LVF1 (priced at $199.95), which slots into the external flash hotshoe on top of the camera. The GF1 can record 1280 x 720 high-definition video in the AVCHD Lite or Motion JPEG formats, and it can focus in just 0.3 seconds via its contrast auto-focusing system.

The camera uses SD/SDHC memory media, and Panasonic includes a battery charger/AC adapter, battery pack, body cap, AV cable, USB connection cable, AC cable, DC cable, shoulder strap and CD-ROM software with each camera.

The Panasonic Lumix DMC-GF1 is available in four colours, black, red, silver and white, either body only (£570) or in two different kits, one with the new LUMIX G 20mm/F1.7 ASPH pancake lens, and the other with the existing 14-45mm/F3.5-5.6 ASPH/MEGA O.I.S. zoom lens: starting from US $ 866,95!

Nikon D3000: a really simple DSLR, a great gift with super saving and limited-time free shipping!

Sunday, December 20th, 2009

The Nikon D3000 is an entry-level DSLR, but don’t let the term fool you. When you place the label “Entry Level” on a camera, it might call to mind a camera with no frills, limited uses, and little more to offer than an automatic shooting experience.

This has been disproved by the latest crop of cameras released in the past two years, and the D3000 continues to set the bar high for an entry-level camera.

This new generation of point-and-shoots and entry-level DSLRs not only push the boundary of low-light performance and mega resolutions, they give that power to a whole new audience of beginning photographers.

Not only do DSLRs offer you manual control over shooting, they give you the advantage of using different kinds of lenses. It’s important to remember when buying a DSLR that you’re also buying into a system of lenses, not just a camera. The power of having a DSLR is that you can place any of your old lenses onto a new camera body in the future.

Enter the Nikon D3000, a new entry-level DSLR with a 10.2 megapixel DX-format CCD APS-C image sensor, 11-point Autofocus system with 3D tracking (which comes on the higher-end D5000 and D90), Active D-Lighting and an AF-S DX NIKKOR 18-55mm f/3.5-5.6 VR lens for $599.

The Nikon D3000 feels and looks exactly like the other DSLRs from Nikon, and is only different from the D90 and D5000, both higher-end models, by a few tenths of an inch. The D3000 measures 5.0×3.8×2.6 inches while the D90 is 5.2×4.1×3.0 inches, though the D3000 weighs a bit less at 1 lb 1 oz, making the Nikon entry-level to prosumer DSLR models almost identical in shape and size as well as overall appearance.

First time DSLR users will enjoy the Guide Mode. It literally walked us through different shoot scenarios via the fixed 3″ LCD screen. An excellent tool, its step by step instructions allowed my niece to move from the operating booklet in no time.

The Nikon D3000 is paired with a Nikkor 18-55mm AF-S DX lens. It will operate with any Nikkor DX and AF-S lens.

Nikon makes it really simple with a thumb dial for tweaking aperture and shutter speed. Metering, focus modes, and exposure compensation are easily controlled via the menu. The D3000 does not shoot in video mode. This model easily shoots over three frames per second in continuous mode. The 3D tracking sensor operates quite well in low lighting.

Get the full Nikon D3000 10.2MP Digital SLR Camera with 18-55mm f/3.5-5.6G AF-S DX VR Nikkor Zoom Lens bundle for US $458.86 (You Save: $91.09 and that’s 17%!) now and enjoy a limited-time free-shipping!

Pentax K-7: a top Pentax DSLR camera now with more affordable than ever with huge savings

Tuesday, October 27th, 2009

Another winner from Pentax announced just before this summer: the Pentax K-7, is now available with a substantial price saving - up to 44% off!

The Pentax K-7 entered the Pentax range as a high-end model targeted at photo enthusiasts because its complexity made it most suitable for experienced SLR photographers.
Featuring a solid metal body, weatherproof sealing and a wide range of user-adjustable controls, it also supported high-speed continuous shooting at up to 5.2 frames/second and HD video recording at 30 frames/second.

The low-down: This 14.6-megapixel camera came fitted with the Pentax 18-55-millimetre lens. This is at the top of the company’s camera range. It has a magnesium-alloy body and is smaller than the K20D. It is weather-sealed and sports an excellent 920,000-dot LCD and 100 per cent viewfinder. It has an HD movie mode. Image stabilisation is by sensor shift. There are body-top and LCD information displays. All important controls are immediately accessible on the camera body, including a nifty white balance adjustment tool. This white balance tool itself is not unique to Pentax but the accessibility is. Among all the desirable features for serious photography is a killer innovation: true in-camera HDR (high dynamic range) processing.

Like: The in-camera HDR processing works by taking three exposures at widely spaced exposure values and then merging them into a single jpeg. Of course, it can really only work with the camera tripod mounted but that is true of any HDR sequence. The results from the Pentax K-7 are splendid and, unlike some HDR output from Photomatix or Photoshop, completely realistic.

High-quality movie recording at 1280 x 720 pixels; 30-frames-per-second
The Pentax K-7 adds a new movie recording function, extending the benefits of SLR photography to the world of movie shooting: For instance, reduce the depth of field to make the subject stand out, or use different lenses to create distinctive visual effects. Beautiful movie clips can recorded at different sizes–640 x 416 pixels, 1536 x 1024 pixels, or 1280 x 720 pixels (16:9 high-definition TV proportions)–at a frame rate of 30 frames per second. The K-7 is also equipped with an HDMI terminal and an external microphone input terminal for high quality sound to match your videos.

Pentax K-7 Technical Details

  • High-resolution, 14.6-megapixel CMOS sensor; compact, magnesium alloy body
  • Weather resistant, dustproof, and coldproof (14 degrees F, -10 degrees C)
  • Fast 5.2 fps shooting with the new PRIME II Image processing engine; top shutter speed of 1/8000 sec freezes even the fastest action in well-lit settings
  • 3-inch LCD; Live View mode, with contrast AF, Face Detection, and optional histogram, grid, and bright/dark area display
  • Capture images to SD/SDHC memory cards (not included)

Pentax K-7 is available now (body only) for US $1,031.89
This means you save $822.12 (that’s 44% off regular price!)

High quality Canon Lenses with great savings - Part 1

Thursday, May 28th, 2009

We love high-quality lenses so here we go with a two-part survey of hard-to-beat Canon lenses with hard-to-resist savings and discounts!

You may find it helpful since savings are in the 30-40% range and since these lenses are not exactly cheap, these offers make them a lot more affordable by pro-amateur photographers!

100-400 mm

Meet Canon EF 100-400mm f/4.5-5.6 USM L IS which is Canon´s long range zoom lens primarily meant for sports-, wildlife- and press photography. Due to its rather small max. aperture it isn´t quite suitable for portraits.
On an APS-C DSLR the field-of-view resembles a whopping 160-640mm lens on classic (full-frame) SLRs.

The lens has a very good build quality - no wobbling whatsoever inc. smooth focusing action. It has a push-pull zoom mechanism which has both pros and cons. You can zoom very fast if necessary but at cost of accuracy. The amount of zoom friction can be adjusted using a dedicated control ring. It´s also possible to lock the lens at a certain zoom position so zoom creeping is not an issue.

True inner focus 4x or 5x zooms in this range aren´t overly likely to emerge in this range due to the physical size requirements for the 400mm setting.

One of the primary and still strong selling argument is the IS (Image Stabilizer).

The lens features a ring-type USM drive resulting in a very fast and virtually silent AF operation. Full-time manual focusing is possible in one-shot AF mode. To avoid unnecessary hunting there’s a focus limiter where you can choose between 1.8m-infinity or 6.5m-infinity.

Price for the Canon EF 100-400mm is US $ 1.400.00 (and that’s 42% off its regular price!)

16-35 mm

On the other side, let’s look at a ultra wide-angle lens from Canon: the Canon EF 16-35mm ultra-wide-angle zoom lens.

Taking over the ultra-wide angle position of the available professional grade f/2.8 zoom lenses from the Canon EF 16-35mm f/2.8 L USM Lens, the 16-35 L II becomes the new standard for professional and serious amateur photographers alike.

Specifically designed for improved edge-to-edge image quality that meets the strict requirements of professional and high-end amateur photographers alike, the lens lets you bring more area into focus while providing greater depth of field. The lens features three high-precision aspherical lens elements–ground, replica, and GMo–that produce even better image quality than the original Canon EF 16-35mm USM lens. The circular aperture, meanwhile, produces a beautiful and natural background blur when shooting at wider apertures. Other details include internal focusing, a ring-type ultra-sonic monitor (USM), and new AF algorithms for fast and quiet autofocusing.

The large 82mm filter size is a first for Canon EF Lenses. High quality filters of this size are expensive and at this point, not shareable on other Canon lenses without a stepping ring. The larger objective end of the barrel reduces the handling comfort of this lens only slightly, but the improved image quality is definitely worth the change. Focus and zoom rings are well-positioned, nicely sized, smooth and well-damped.

Price for the Canon EF 16-35mm is US $ 1.399.00 (a 39% cut-off from list price tag).

50 mm

Last but not least a super-classic lens we all started with: a 50 mm.

Actually, this is the Canon EF 50mm f/1.2 L USM!

The Canon EF 50mm f/1.2 L USM lens is a peerless standard lens for Canon digital SLR cameras.
The lens is suitable for any shooting situation, with a lens coating and construction type that are optimized to minimize the ghosting and flare that frequently occurs when lenses are used with digital cameras.

The Canon EF 50mm f/1.2 L USM also offers an ultra-large aperture ( f/1.2 !!!) that produces a narrow depth of field and the type of soft background blur so loved by photographers everywhere.

The high-performance, weather-resistant lens delivers all the superb image resolution and contrast you expect in a Canon L Series lens.

What we really love about it: picture quality - from f1.2 thru f2.8, the lens works superbly. AF is fast & faster compared to 50mm 1.4.

List price for the Canon EF 50mm f/1.2 L USM is now $1,499.00 (which is some 35% cut-off from its regular price).

More Canon lenses soon up & coming in part #2!
