Q and A: What’s the deal with the new cameras lacking pentaprisms and reflex mirrors?

Question

What is the advantage of the new cameras without a pentraprism and a reflex mirror … like the Micro models from Panasonic and Olympus, and the Samsung NX? Is the benefit simply smaller size versus a Digital SLR? In that case, why wouldn’t someone just buy a smaller camera like the Canon Powershot G11 which also has a built-in viewfinder? R.N.

Answer

The primary appeal of the “mirrorless” or “non-reflex” cameras – and their new petite lenses – is certainly the greater portability. Of course there are some intangibles as well with the latest Micro Four-Thirds cameras: the Lumix GF1 and particularly the Olympus E-P1 and E-P2. These models are very classy and they feature rangefinder-like styling, which appeals to many camera buyers. (See my Olympus E-P1 Review: Field Test Report ) But let’s discuss some of the other important aspects to clarify additional issues.

As this illustration of the Lumix DMC-GF1 versus the Lumix L10 DSLR indicates, a Micro Four-Thirds camera can be much smaller than a DSLR especially if it omits a viewfinder. Since the lenses are also smaller, the entire package is substantially more portable. — As this illustration of the Lumix DMC-GF1 versus the Lumix L10 DSLR confirms that a a Micro Four-Thirds camera can be much smaller than a DSLR especially if it omits a viewfinder.

Q and A: What filters should I get for my new DSLR?

Question

As a first time digital SLR camera buyer, I am wondering what filters I will need for my Nikon D5000 with the AF-S 18-55mm VR and 70-300mm GED VR lenses. When I had a 35mm SLR, I owned several types of filters, but sold all that long ago. Are filters still necessary in digital photography and do I need the expensive multi-layer coated filters? L.W.

Answer

The only filter that I use is the circular polarizer-an indispensable accessory for outdoor photography, with several benefits. This accessory can deepen the color of a blue sky, wipe glare from reflective surfaces (except unpainted metal) to allow the true colors to show through and reduce the effects of atmospheric haze so the subject will appear more sharply defined. Rotate the polarizer in its mount while viewing the scene through the viewfinder, or on the LCD screen in Live View. If it does not seem to have much effect, change your shooting position; you’ll get the greatest benefit when the sun is to your side. (more…)

Q and A: What’s the deal with the new Micro Four Thirds format?

Question

Can you explain the new Micro Four Thirds format? What is the point of a camera like this compared to one that fits into a shirt pocket like my Lumix FS25 with 29-145mm lens? I see that both Panasonic and Olympus are making Micro cameras now, but they’re not very small and they are very expensive. Why would anyone want one of those? J. N.

Answer

JN, yes, Panasonic was the first to introduce a Micro Four Thirds camera, the Lumix DMC-G1 Panasonic Lumix DMC-G1 12.1MP Digital Camera with Lumix G Vario 14-45 mm f/3.5-5.6 ASPH Mega OIS Lens (Blue)($623, with 14-45mm zoom lens). Their more recent model, the brand new DMC-GH1 ($1500 with a 14-140mm lens that’s perfect for video capture), includes some upgrades and an HD Movie mode.

Olympus recently announced their new contender, the E-P1 Olympus PEN E-P1 12.3 MP Micro Four Thirds Interchangeable Lens Digital Camera with 14-42mm f/3.5-5.6 Zuiko Digital Zoom Lens (Silver Body/Black Lens) ($800 with 14-42mm lens); this model also features an HD Movie mode. (more…)

Nikon D700 Review: Field Test Report

Peter Burian tests this remarkably fast, rugged professional DSLR with full frame sensor and over-sized pixels for stunning image quality

Combining the best features and technology of the D3, the Nikon D700 is far more compact/affordable and 9.6 ounces lighter. This new professional model shares the fast EXPEED processor and full-frame 12.1 megapixel CMOS chip and it’s nearly a rugged as the D3 thanks to a weather-resistant magnesium alloy body. The primary differences are a slower (but still fast 5fps ) continuous drive speed, reduced viewfinder coverage (95% vs. 100%) and only a single CompactFlash card slot. But the D700 gains a built-in flash (great for wireless remote flash control) and an automatic sensor cleaner. Add the optional MB-D10 battery grip and it can fire long bursts at a blazing 8fps.
