DSLR Recommendations?

Q. Need a little advice here. I am semi-literate in DSLR terminology and use and I think enough so to make at least a relatively informed comparison between products but I am very inexperienced with them none the less.

My father is planning on buying a new DSLR that he intends to use to take landscape photographs with the highest possible detail. He is not a photographer and not experienced, his requirements are high build quality, the unit must be able to keep dirt out as best as possible and it may well get wet, also, though I'm fairly sure he'd be hard pressed to perceive the extra quality, he is insistent upon very high sensitivity and quality. So far he is focusing his comparison upon canon 40d. it's equivalent in Nikon (I've forgotten the name) and the Nikon D700, the last one is one he looked at and had some advice on and he was told it was a professional camera that throws you in the deep end and is not easy on amateurs though my father tends to like to buy things given that type of description regardless of whether or not it's best suited because he tends to think it will be the best overall product because it is high range and high price.

He seems to be willing to spend any between 1000 to 2000 Pounds Sterling on it, though I'm rather hoping I can convince not to go quite so off the rails on something he's unlikely to use very often, anyway what camera (any camera not just the ones I mentioned) do you think would be good for this type of photography with an amateur behind the lens?
Seems to be some controversy over built in image stabilization and lens built stabilization, with where I am in my research and knowledge though not experience I'm inclined to believe that image stabilization is better built into the lens for minimal interference to the end result. Aside from the convenience of working with any lens, does any have any reason to recommend image stabilization built within the camera body?

A. The D700 is a wonderful camera if you want or need a full frame sensor. Here are some of the features:
12.1 megapixel full-frame sensor (8.45µm pixel pitch)
Image Sensor Cleaning (vibration) *
ISO 200 - 6400 (with boost up to ISO 25600 and down to ISO 100)
Also supports DX lenses, viewfinder automatically masks (5.1 megapixels with DX lens)
14-bit A/D conversion, 12 channel readout
Same ultra-fast startup and shutter lag as D3
Nikon EXPEED image processor (Capture NX processing and NR algorithms, lower power)
New Kevlar / carbon fibre composite shutter with 150,000 exposure durability *
Multi-CAM3500FX Auto Focus sensor (51-point, 15 cross-type, more vertical coverage)
Auto-focus tracking by color (using information from 1005-pixel AE sensor)
95% coverage, 0.72x magnification viewfinder *
Auto-focus calibration (fine-tuning), fixed body or up to 20 separate lens settings
Scene Recognition System (uses AE sensor, AF sensor)
Picture Control image parameter presets
5 frames per second continuous with auto-focus tracking*
Optional MB-D10 Battery Pack (same as D300), increases burst rate to 8 fps *
UDMA compatible single CF card slot *
3.0" 922,000 pixel LCD monitor
Live View with either phase detect (mirror up/down) or contrast detect Auto Focus
Virtual horizon indicates if camera is level (like an aircraft cockpit display)
HDMI HD video output
'Active D-Lighting' (adjusts metering as well as applying D-Lighting curve)
Detailed 'Control Panel' type display on LCD monitor, changes color in darkness
Magnesium alloy body with connections and buttons sealed against moisture
Improved Info display on main screen *
DPreview said of this camera "The D700 joins the D3 as a fully-fledged 'professional' model; it has the same tank-like build quality "


The D300 is in the price range and also a great camera with superior photos with an APS-c sized sensor.. It has a flexible program mode and auto white balance and auto ISO so you can use almost automatic. It does have more options and more features to learn. It also has an aperature priority mode, shutter speed priority mode, and full manual. It does not have programed modes like Auto, Portrait, Landscape, Children, Night etc. These auto modes tend to be limiting and many people outgrow using them anyway. So Nikon does not put them on any of the high end cameras.

Nikon and canon put the image stabilization in the lens. Some other manufacturers it in the body. In lens system work smoother and faster with less impact on focus times. So that is why the two largest camera manufacturers went with in lens systems for stabilization.

So either of these he could start out shooting in program and then then use the other setting as he gets more comfortable with him. If he does not want that level the D60 while it does not give you the features of the D300 or D700 gives you all of the features most entry and mid range photographers use and it would give you more money for lenses and such. for landscape he is definitely going to want a good fast wide angle lens.

Email me if I can help

Additional on image stabilization From the Canon white paper this explains some of why Canon and Nikon chose in lens.The same argument for Nikons VR over the in body systems would hold true, hope it helps

"Some of Canon�s competitors have chosen to use in-body image stabilization. The technique involves moving the image sensor in a controlled fashion, based on signals from movement detecting sensors in the camera body. The obvious advantage of this system is that users have some sort of stabilization available with almost any lens they connect to the body. Short focal length lenses require smaller sensor deflections; 24 or 28 mm lenses might need only 1 mm or so. Longer lenses necessitate much greater movement; 300 mm lenses would have to move the sensor about 5.5 mm (nearly 1/4�) to achieve the correction Canon gets with its IS system at the same focal length. This degree of sensor movement is beyond the range of current technology. Short and 'normal' focal length lenses need stabilization much less often than long lenses, so the lenses that need the most help get the least."

Added: and again a bit more on the image stabilization controversy

And Nikons View on it
"(Image Stabilization) in the lens effectively corrects blur in the finder as well as in the image itself. A clear view makes it easier to capture your subject in the focus frame and confirm photo composition.
On the other hand, with cameras that correct the image blur by adjusting an image sensor (cameras that correct image blur inside the camera body), the image in the finder remains blurred." - Nikon
We probably will not decide here which works better and they both work to some degree but I do love a good debate on this type of thing ~grin~


Can LCD Monitor on Canon ESO 20D can be used as a Viewfinder?
Q. I did not see it in a Manuel and it is very hard to take photo through the little viewfinder eyepiece.

A. Live view on dSLR's is a relatively new thing that did not show up until about 2008 or 2009 on some dSLR's but NOT all.

The Canon EOS 50D was the first of that series to have live view. 40D or older do not have that feature

As far as using the viewfinder, photographers have been using them for over 50 years without a problem. You may have to refine your shooting skills to make using it more intuitive
