3000mm Eq with Q

This was show with the Q/Tamron 300 f2.8 and Tamron 2X TC.  It is not a great picture but is over 3000mm equivalent.

Well for 3000mm equivalent it ain't bad!

A bit of PP (contrast & NR) will help a bit too (I am assuming that was OOC ?)

Cheers,

Rod

Re: 3000mm Eq with Q

It's not the greatest image in the absolute sense, but what would the subject look like if you had used a DSLR with the same lens from that distance, instead of the Q?  It would have been worthless crap, most likely.

And if you had stacked TCs for the DSLR, you would have lost a lot more contrast and introduced other artifacts that would not have been create by higher pixel density.

Agree John.  This is not a great quality photo but cropping the K5 to get the equivalent would have been a challenge also.  I will do more testing to see if the results can be improved.

The benefit of something like the Q over cropping is even bigger with video, as cropping video gives way too little resolution.

I really believe that it would be better to have a few lenses, and multiple bodies with different sized sensors, than to have a wide range of lenses, in many ways.  If any of the DSLR makers made a full APS-sized body with a comfortable grip and smaller sensors, people would laugh at first, until they saw the results.  Imagine a 200mm f/2.8 or 400mm f/5.6 lens on a Q-like sensor with AF, camera-controlled aperture, and IS, with a camera body that doesn't turn when you manually focus the lens.

Especially with a tripod-mounted lens, changing bodies is a snap.

Re: AF on K to Q Converter

What would be really sweet if Pentax had an AF function on the Q to K converter like Nikon does with their 1 series converter.

I would sure look at getting the pentax q to k adapter if it was auto focus.

Bring a bag of batteries with you always, if that ever happens!  The Q is battery-hungry enough, as it is (how do you turn off that stupid flashing red light?).
