Originally posted by nvarner Hi GlenG ! Sorry if I was not clear, the D90 is back ! lol I was saying that in September the D90 was shipped to Nikon for a back focus issue which in my opinion they did not fix but certainly charged me $250 as though the did, and I had an event that I shoot annually so I purchased the K30 at that time. The D90 actually came back a week after the event lol
1. We're going to Cancun (but probably won't venture too much from the resort area)
I may get a used Sigma 70-300 apo dg maco they are cheap and will give me the extra reach. I want longer on vacation because there will be some performances and I'll be farther away than I was with the acrobat picture. Thanks for the complement.
2. So maybe that used sigma and a normal prime, perhaps, I like to 40 2.8 very much but inside it seem a bit too tight but I take it and be okay
3. I have a Bday event to shoot and I'm thinking I'd like to shoot the K30 vs my D90. my D90 is just heavier I have a grip on it and this thing and that thing. lol I love the camera but thinking I like to use it more now for studio shots or paid environmental portraits that type of thing, if that makes sense to you.
There is a tamron 70-300 in the marketplace for really cheap and there also is an 18-55wr for $120 right now too (I have nothing to do with the sellers and I am not vouching for them). I've used the tamron 70-300 and it is very sharp though it has a lot more purple fringing than the Pentax 55-300. I think I saw a DA-L 55-300 in the marketplace too.
If I were going to the tropics, I would have a WR lens with me for sure. You could sell your non-WR 18-55 for maybe around $75 for all the new k01 owners that want something a bit more flexible than the xs40.
One other thought is to get a superwide that matches up w/ your 28-70 - So I'm thinking like the Tamron 10-24 or Sigma 10-20. Maybe this should be your long term direction since if you can't get the 18-135, these super wides are about the same cost as the 18-135. Personally, for architecure and landscape shots, I find superwides indispensable. Given your shot distribution, a superwide would force you into lens changes though... no free lunches, I'm afraid.
My travel kit is usually a Pentax 12-24, Tamron 28-75, Pentax 55-300, a fast prime (usually Pentax 77 1.8 or Sigma 30 1.4) and a macro (either 35 limited or 100 WR). I'll always bring a WR lens for those unpredictable days, but if the weather looks clear, it stays in the hotel safe. So in my cam bag, I'll have 12-300mm covered and I'll have a fast lens for dark areas or when I want a shallow dof and I'll have a good close-up lens (though the Tamron 28-75 does pretty good for detail shots). Although I like the 40 2.8 and the size is great, it usually does not make the trip as it's redundant in my kit (having 28-75 covered in 2.8).
Really, your problems could be simpler if you weren't running two systems... but I'm sure you have your reasons.
