Originally posted by Susinok I am still drooling over the K-3. B&H has a nice K-3 bundled with a DA 50mm 1.8 lens and the DA 18-135 WR lens. The price is steep, but my thoughts on this is that the 23.35 MP CMOS is a huge jump over the 14.1mp I have now, whereas the K-50 is only a 16.3mp. I want my new camera to last a long time, and not need an upgrade for many years. I also want to eventually make prints of a descent size.
Is the DA 18-135 good or just another kit lens? The DA 50/1.8? Or is it better to get the camera body and a different lens. If I do get a new body, I want a good lens to go with it, not another kit that is not up to snuff.
I'm not going to buy it tomorrow. At that amount of money I will think about it a while. But it makes more sense to me to go with the higher MP camera so it lasts longer. That was one thing about print cameras, they didn't go obsolete so quickly. I worry that if I get the K-50, I'll want to upgrade in two years. Even if it DOES come in shiny red.
Depending on what you photograph you may be overly fixating on megapixels. For the me the big deal about the 16mp sensor wasn't the increase in mp (for me it was 10 to 16), it was the dynamic range and noise reduction over previous sensors. In that sense I don't think the 24mp is that far ahead, which is why you might be better with a 16mp-generation model and spending the extra money on lenses.
The one feature you have now but might miss on a K50 is a top LCD. You'd need a K5 or K3 if that's an issue for you.
Obviously if you make very large prints or if the last ounce of resolution is important, then you'll not only want a K3, but you'll need very good lenses to go with it. I don't think you're going to get the most advantage out of a K3 with lenses like your Tamron 28-300, but you will see an improvement in dynamic range and noise with any 16 or 24mp-era body vs. what you have now.
I think you have to not concern yourself with not upgrading for many years. Think of it as what you used to pay for disposable film, now you spend for disposable bodies.
But I don't buy into the theory of lenses, even good dones, lasting forever either. Partly because of the whole FD experience, but also because if manufacturers want to keep selling higher resolution bodies, they're going to have to up their game with lenses. Remember that with a number of lenses today you're limiting yourself to APS, and it might be that tomorrow you're going to want FF or even some other size we don't know about yet. And even with Pentax, which has been among the best for backward compatibility, relatively few people really want to use a pre-A lens, much less an M42 that requires an adapter if you want to use it. And it's not hard to imagine a new 50-135 or 60-250 that focuses five or ten times as fast as the current one, for example. So depending on how you use the lens, you might or might not feel compelled to upgrade, just as you feel compelled to upgrade bodies.

Really? Certainly the Samyang bunch (Rokinon, etc.) would have to be clumped in with the "lower end", so that pretty much limits you to... almost no choices for lenses at all.
