I already have a k-x and I plan to get one more body for my next trip. Idea is to use one body with Sigma 10-20mm and another with 70-200mm. Which one do you suggest - k20D or k-x?

I was thinking of getting k-x but then someone suggested that for landscape and low ISO use K20D has advantage over k-x. Any opinion? I am not worried about weather-proof. IQ will be the major factor in deciding which one to go for.

Which one will you get. Thanks for the help.

Both great cameras and the K20D is excellent for landscapes, but I suspect the Kx is not too shabby.

One thing to consider is the form factor and advantage of having two of the same body. If you like/are used to the handling of the primary Kx you might be more inclined to use the second body more often due to familiarity with controls and handling.

[Ira]

I would probably get another K-x because of familiarity with the controls, as Biff said.

But...

From what I've seen from images here, I think the sensor on the 20 is a bit more special.

So I am absolutely no help to you at all in making this decision.

[Andrew Lang]

if you get the 20d you probably will want to sell your k-x and get another one... Then you will want all weather-sealed lenses for your weather-sealed bodies... then you'll get a da* lens and only want them. you'll go broke and end up poor for the rest of your life, but, you will have a nice camera

(i love the 20d and i switched from the k-x. i'd do the 20d just because it gives you the benefit of weather-sealing)

[yusuf]

@Ira, Biff, hmm, I wouldn't mind a bit different controls if k20d offers special characteristic as I understand, any comparison shots please?

@Andres, why did you switched? I am not very inclined for weather sealing as I mentioned so that will NOT be a reason for me I already have pretty good glasses so need an additional body so that I can use them without switching.

FWIW, I've brought the following on assignment:

K20d + DA* 16-50 F2.8
K-x + DA* 50-135 F2.8

The K20d does give you a couple more megapixels to crop with. And the high ISO capabilities of the K-x work well with longer lenses. I had no problem switching between the two, particularly if using Tv or AV where most of the adjustments happen via a single control wheel.

Having two different bodies does require different chargers for both, which is a pain when you've also got a laptop charger and a phone charger, etc...

Well if you want imagequality with low iso, the samsung sensor is the better choice. You can also think of the K-7, wich is also absolutely great in the iso-range 100-400. I had K20D and K-7 (now K-5) and I preferred the K-7 over the K20D.

+1
The price of an used K-7 is very affordable (less than $700 at keh.com), and the K-7 woud be an excellent complement to the K-x.

I upgraded to the K20 from the K100 primary for the 100 ISO. I like it a lot since 99% of what I do is at 100. I also like the top back lit LED - helps in the evenings. It is a wonderful body.

I have also found (and maybe its just me), that for bracketed shots, especially in the evening (ambient low light), that +/- 2 ev is just too much (for the sensor), so I am now sticking to 1 and sometimes 1.5 ev, and use 5 shots rather than 3 in order to get as much DR as possible. Which reminds me - I really like the dedicated Bracketing / HDR button. On the topic of +/- 2 ev, the images look fine, however when stacked, all the software utilities over amplify the images and the combined noise is terrible (even if you use NR prior to stacking). You may not care about HDR.....

The user controls are wonderful when compared to the K100 or the entry level lines. The two (front and back) wheels I really like.

I even wonder whether the K10D, K-m/K2000 or K200D may suffice for this application. Good ISO 100 performance is what you'd want, so if the K-5's out of the question then there are good options there in the old CCD sensor-based dSLRs. But between the K20D and K-x, it'd be the K20D (but you couldn't go wrong with either...)

[yusuf]

Yes, I have been keep on hearing about low ISO performance of non-k-x bodies, is that really that much of a different at low ISO between "k-x v K20D" or "k-x vs K-7"? Ideally k-x's superb DR should have made it a choice for even lower ISO but somehow k-7 or k20d is praised for lower ISO which is bit of surprise to me.

@johnmflores, since you have both, can you post some pictures by shooting with both the body with the same lens. Really trying to understand what's the real difference at low ISO.

Thanks

[Steve Beswick]

If you are really looking for something different in the low ISO area, I would say give the K10d a try. From what I understand, the look is very different from any of the newer sensors.

[clockwork247]

k-x, if you had a black one, get 1 in white, wear both when you walk around, epic cool.

[Ash]

Sony's CCD sensors have been well known for their superior low ISO DR. Not sure about comparing ISO 200 between the K10D, K20D and K-x, but ISO 100 is definitely won by the K10D.

[koper]

you can use two bodies k20 or k10 with your sigma 10-20
it is mach easier to make hdr photography's with this bodies
k7 is good for tele lenses for sport photography
i always carry in my bag two bodies
