Hi all,
I'm taking the family to Vietnam and Malaysia for 3 weeks over Christmas and into the new year and am considering a long overdue upgrade.
My kit is outlined below and my question is really targeted at someone who has moved from K5 to K3.
I expect there will be a lot of walking, buses, trains, etc and am considering either the K3 or DA* 50-135. In the long term would like both but the Treasurer is not playing the game I'd like right now. I can comfortably walk around all day with the 16-50 attached and rarely use a neck strap. With the 70-200 attached, fatigue does become an issue but I really like the image quality from the K5/Sigma combo.
My options are:
1) Replace K5 with K3 for better video control and increased resolution. I don't do as much video as I would like with the K3 partly because it is not flexible enough. Would also mean I could put my non-WR 18-55 or DA35 on the K5 for my wife/daughter to use.
2) Replace non-WR Sigma 70-200 with DA* 50-135. As well as having WR, it would seem from reviews that I will not be going backwards in terms of image quality from the Sigma to the Pentax. I would lose the reach, but I won't really know until I hit the ground if that will be a real issue. I will probably take the 70-200 and leave it in the apartment unless I get stuck and think I will need it.
3) I guess a 3rd option might be to simply get a couple of primes - perhaps a 70 or 77, and take a chance on not needing the extra reach.
I'm not a huge fan of using flash so ISO is important - this may be due to the questionable flash performance of the K5/AF-540 combo. This seems to be much improved in the K3?? I have read mixed reviews regarding which of the K3 or K5 has better ISO performance.
Any and all comments or advice would be appreciated.
Cheers,
Darren.
