Pentax K-7 vs Nikon D90 - High Iso criteria?

I have not used the Pentax K-7 yet but my current camera is the 50D and I used the Nikon D90 up to amout 2 weeks ago for about a year as my main camera. Personally I think the D90 is the better camera, though not as strong of a build it does have better ISO performance and shows better detail. I switched to Canon as I am working towards my BA in photography and thinking I will soon go full frame. The 5D classics are getting cheap on the used market. I also like the Image overlay and multple exposures which Nikon offers and Canon don't. Don't get me wrong, I love the 50D. If you shoot at lower ISO settings it is capable of great image quality. The 6FPS is perfect and faster than the D90. Though I don't need the 8 of the 7D and higher. Plus the Canon is built like a tank over the D90, though for plastic the D90 is about the best you can get. Mine survived some nasty falls that I am sure would of killed any Canon Rebel or other plastic camera. Plus with the price drop (I got mine on Amazon for 1161 with 28-135 lens. Sold the lens for 250) its almost a steal. So you really need to decide what features you want. Both the 50D and D90 are top of the line cameras for there class. The K-7 I have heard huge raves about aswell but like I said never used so I can say for sure. I do know Pentax has some great glass but lacks third party support, this will hurt when buying lenses and accessories. Read the reviews, and try out the cameras at a local camera shop if you are able, I think any of em would work well.

He tenido buenas experiencia con los productos de sitios web, había comprados cámara muy buenas a un precio muy bueno, como viajo mucho he comprado y una cámara para el coche porque nunca se sabe cuando la necesitas, la cámara va perfectamente, buena resolución y un buen ángulo, aunque a lo mejor no me haga falta, a este precio es mejor tenerla porque es muy utilla.

The K-7 uses a Sony built sensor that is supposed to be superior at high ISOs to the D90's Sony built sensor.

The K-7 does good performance at high iso.

Pentax K-7 Digital SLR Camera + 18-55mm SMC DA + 50-200mm WR Zoom Lens + 8GB Card + D-LI90 Battery + Case + Accessory Kit

Pentax K-7 14.6 MP Digital SLR with Shake Reduction and 720p HD Video

https://www.amazon.com/dp/B0028N7442?tag=dcmb-20



Review :

Pros:

Rugged, full weather seals. Rain, snow, or dust won't slow it down.

Compact Size with a magnesium alloy shell of stainless steel chassis.

Selection of lenses designed for the APS-C imaging sensor

Shake reduction with every lens

Ergonomics

External Mic in video mode

Very quiet shutter

Industry first Composition Adjustment and horizon level (separate features)



Cons:

Battery life in Live View/Video mode.

Not a beginners camera unless you have a strong desire to learn about photography

High ISO performance could be a bit better



What previous Pentax users will notice:

Refinement, refinement, refinement

Low light autofocus is fast and accurate (inline with the competition now)

AF-Continuous is fast, but not class leading.

Ergonomics different from previous K10d and K20d (maybe good, maybe bad depending on your position)

Insignificant change in image quality from K20d

Can disable long shutter noise reduction for shots 30 seconds or less

Excellent sensor dust removal



Who should buy the K-7? Anyone looking for a prosumer dSLR (Nikon d300, d300s, Canon 50d, etc) that they want to take anywhere. This thing is for serious adventurers, with its full weather sealing and wide array of weather sealed lenses (DA* or WR series lenses). Going on a trip to Alaska? Hiking in the back country? Canoeing down the Colorado? Or even if you just want a smaller dSLR with all the features of the big boys from Canon or Nikon. This camera steps up the competition.



What new to Pentax users should be aware of? The camera makes slight noises when you pick it up or turn it on. The sensor is free to shift in its mount due to the shake reduction system. This is totally normal, but scares some first time users where they think something might be broken.

Nikon D90 DX 12.3MP Digital SLR Camera

http://www.amazon.com/dp/B001ENOZY4?tag=dcmb-20



Review :

Several months before the D90 came out, I bought a D60 to hold me over until the D90 was released. Well, I've enjoyed using both cameras, but this one is a huge step up and more suited to an advanced enthusiast, like me. It's a real pleasure to use.



UPDATED AUG 2009



ERGONOMICS - The D90 is solid, tight, and well-balanced with the 18-105 VR lens. It's always ready and it shoots very fast. I love all the direct access buttons; they're easy to press, with good tactile feedback. And since you're not going into the menus as much, you can work faster. It's heavier than the D60, but that's OK. It's still very manageable to carry around and it fits my average-sized hand better too. The shutter sounds different than the D60 (if that matters to you). It sounds more like a professional camera; more like a fast "whoosh" than a "click-click". And there are so many internal customizations that you can set it up exactly as you want.



LENS - Biggest surprise was the 18-105 VR lens which I expected would be ho-hum, but turned out to be pretty sharp and clear. Better results than the 18-55 VR. We've really come a long way from the days (30 years ago) when you were cautioned to ALWAYS to buy a prime lens, NEVER the kit lens because of it's poor image quality. With computer-aided design and new technology, that's not true anymore.



IMAGE QUALITY - I shoot RAW for maximum detail and the ability to adjust settings afterward if necessary - like exposure or white balance. Image quality is very good to excellent depending on your RAW converter. To my eye, best results are obtained with View NX/Capture NX, but Adobe ACR/Lightroom still do a very good job. When shooting JPGs using the Standard Picture Mode, images are sharp and colors are true, without over-saturation. You can always use different Picture Modes and customize any of them to get closer to the in-camera results you want. For example, you can boost saturation and contrast and save the setting as your default if that's what you like.



LIGHT METER - Metering is fine and seems to be quite accurate in most cases. I use matrix metering mostly. As with any camera, you have to get to know the meter. If I had to be VERY critical, I'd say when it's pushed, it's more likely to preserve shadows than highlights, usually when Active DLighting is on. To me that's a good thing. [...] mentioned a slightly "over-enthusiatic" meter in its review. The good news is: if you really feel exposure results are not to your liking (whether over or under exposed), the meter is fine-tuneable, so go ahead and customize it as you see fit. I would just work with the meter first -get to know the camera and
