I sure hate to ask this.... but I will! Lets say I put my 300mm Super Takumar full frame lens on my K3 and take a picture of the duck from 30 feet and then while I and the duck hold our positions I put the DA300mm lens on the K3 and take the same shot.. Will the two pictures be the same....?

Yes. Same focal lenght, same field of view on the same sensor.

[OJGoreng]

Although in all likelihood, the one taken with the DA*300 will show more detail, because it's a superior lens. I find that the K3's sensor tends to outresolve my Sigma at the long end, for instance. I don't find my k f/4 300mm to be any better than the Sigma (worse when used wide open, in fact), an I'm guessing the Takumar will be similar in performance to the K f/4 300mm. But indeed, More Duck would take up the same size no matter which of the two lenses you'd use.

Case in point, here is More Duck...not the exact cut-out I used in the example, but roughly similar. K3 with Sigma 170-500. I could easily blow it up more, but it wouldn't really show more detail. In fact, it's pretty soft already.

In terms of image size - identical. In terms of IQ, not absolutely certain but it's likely the newer lens will provide better sharpness, less fringing, etc.

To get back on topic, there is a 97% chance that you would get the same composition but only a 22.7% chance that the IQ of the K f/4 300mm would be superior. If instead you used the supposed 135-380 you would get a 72% chance of having equal or superior IQ and could even get more duck if you so desired. Combined with the self purported credibility of that lens being released, you have a 46.8% chance.

Thanks, I think I have it visualized in my head now!

If they do come out with a K-60 in the next few months what are the chances the price of the K-3 will go down at the same time? How long was the K5/5 II out before the price dropped?

K-5 came out in sept or oct at $1700 or so.
K-5 in november (black friday) was $1450 or so.

Wow, lots of detail. Interesting, it took the K-5 12 months to drop 25% and the K-5 II half the time. It stands to reason that the k-3 should drop by that much in 6 months or less. We can only hope!

[Kunzite]

Hope that Pentax isn't doing well?

[kosmoejtg]

I don't want Pentax to do poorly, I just don't want to buy and find the price goes down significant shortly thereafter. Another way to look at this is that the K-5 held its price longer because it was a major upgrade at the time. The K-5 II was simply a mild update so it did not have as much demand and therefore the price needed to drop to keep sales at some level. This would be an argument for the K-3 to drop in price more gradually like the K-5. Either way I will still probably get a K-3 in the near future.

[bobmaxja]

K-60 will not compete with the K-60 . Should have no effect on price

[Giklab]

K-60 will not compete with the K-60.

Most definitely not

They are way too closely matched.

That is a fact of life when dealing with electronics, which camera bodies are now, they depreciate rapidly.

I got to wonder how many of these rumors are just trolls having a laugh. Or if Ricohtax might be using some guerilla marketing tactics, planting rumors, to generate spin - like some other companies.
