Perfect lens suite?

Thank you all for great feedback, thought provoking questions, and photo examples. For "macro" stuff I have normally stuck with foliage, but probably because I could never get close enough to bugs anyway (with the exception of large, too-cold-to-be-scared, dragonflies). So the 100mm will open up a new world. As for telephoto, interesting idea about the 300mm + 1.4TC. That's basically a 420 @f5.6 and the combo is about $500 cheaper (and a bit smaller) than the 150-450.

I do tend to focus on zooms instead of primes, since I'm usually hiking trails and need the load to be manageable. For me, at least 1/2 the reason to carry the camera is to "be out". The other half is part art, part chronicle. Sometimes I have "faked a prime" by deciding what to set the zoom at before putting the camera to my eye and sticking with it...it's definitely an interesting exercise, but I don't want to build my whole gear arrangement around it.

It looks like I have a couple configuration options, and both would start with the FA 100 macro and the DA* 16-50 as the "heart". Those would really be an improvement, opening up a new world, and better image quality than the 16-45, and together probably comprise enough strain on my wallet in the near term.

Later on I'll have to decide what to do on the long end. The 50-135 is tempting for lower light levels, but from the reviews it seems like the 60-250 is amazingly sharp. But at the very long end...for the size of the 150-450, I could probably pack an Olympus OMD E1 ii with a 300mm + TC (which ends up being an 840mm equivalent)...that's some serious reach that fits my mobile mode. Something to ponder over the next year.

Thanks again all!

I'm pondering upgrading my current lenses. I have a K-70 with the following Pentax lenses: 16-45mm, and 55-300mm. This gives good coverage, but I'm missing a few things. The main thing is a macro lens: although the 16-45 can focus down to a few inches, it's not very clear...definitely fuzzy at f4, reasonable at f5.6, but it doesn't get close enough for what I want to get pictures of. I actually get better "close up" results from the 55-300mm at a couple meters away. I'm tempted by the 100mm FA lens, but has anyone had experience with this lens on an APS-C sensor? Are there any good 3rd party macro lenses? Weather sealing is a "must-have"...

The other missing thing is a good super-telephoto. 300mm is okay for large birds, but for small birds in the wild it's just not working for me. I've been tempted by the 150-450, but I'm not sure it's going to make that much of a difference, plus I'm not crazy about the size (for this I'm considering M4/3 as an option).

Lastly, my current lenses are "slow"...f4 at best. But current lenses are decent, but the 16-45 has fairly severe chromatic aberration...a recent high contrast image of "trees against the sky" was practically purple throughout. I'm very much considering upgrading everything, as f2.8, or even a constant f4 would be preferable.

Basically I'm after a set of high quality lenses that offer the FF equivalent of 24-600 + macro. Any opinions/experience with the current Pentax lens lineup, that is weather sealed, that would fit the bill?

I've had my K-70 out in -30C several times now. In -20C it lasts a good 2-3 hours under fairly constant use. At -30C it's more like 1.5 hours before I need to swap batteries. I have a couple extra batteries (one from a defunct K-30, and one 3rd party) so I've never been completely out of juice on a day outing.

Hello fellow 'pegger :) I had my K-70 out yesterday in Bird's Hill Park for about 3 hours total, it was -31 out there. Once the mirror started "triple-flipping"* I switched to a warm battery and the problem went away. Otherwise the camera performed perfectly: screen, autofocus, exposure...no issues at all. I imagine a K-1 would perform just as well, just have a warm battery available to swap to.

* I have a thread on this triple-flipping issue, here:
Found the cold limit? - PentaxForums.com

Edit: when you're done, just make sure to either leave your camera in the bag or put your camera bag inside a plastic bag before coming inside, and don't open it until the camera reaches ambient temperature.

What maximum ISO to use on K-70 default auto ISO range?

That's what I do. For birds, where detail matters, even 3200 is a bit much for me, but I'd rather allow the shot.



Interesting thought about custom NR, I will have to try that out.
