Personally I would not pay $85 for that lens, but would go for the Tamron LD Di f/4-5.6 instead (or spring $200 for the Sigma APO, but I assume you're on a fairly tight budget like me )
I wish this advice had come a couple of days ago, as I've already gotten it. It seems OK to me--not great, but not terrible, either.

Here are a few images taken with the Sigma 100-300:

Heather it looks like you got a much better copy than I did. Very nice colour with it and decent sharpness as well. You did ok there I think.

Sorry to be hijacking your thread Hin...

I did put in a price quote request at B&H for both the F70-210 and the Sigma 100-300. Perhaps if I can get enough for both of them, I may just go on ahead and order the Tamron 70-300 from B&H--if not, I'll hang on to the Sigma and put the 70-210 on Fleabay with a decent reserve price--they're getting around $100 or so there.

Funny Hin, you're keeping the K mount lens and now selling my favourite lens that gets the most use in my kit. I'd never sell the Tamron, ever.
Oh man, I am making all the wrong decisions. I trust your opinion and I will re-think seriously. Thanks for the pointer. I put Tamron to be the last few items to sell and schedule it last in Hin's Camera Gear - Hin's Tech Corner . Thnings are yet in the planning and I will take my time to sort out what I don't use in my gear list.

What I want to achieve is to cut down on my unused gear. I buy too many things in impulse purchase and I end up having 9+ unused lens for months. The Pentax K 45-125 is one of them purchased about 5 months ago and not a single shot was taken until last weekend. I shot test pictures for selling the lens -- how pathetic one get in LBA in having gear just for test shots to sell at a reduced price.

The great AF540 flash that I purchased from you is another example of unused gear. I buy first and use and think later. It has become a problem for me. No matter how inexpensive an item is, any unused gear in my possession becomes a very expensive items, hence my current act in setting up a lens roadmap to undo my mistakes. By the way, I would force myself to use the flash with simple gear like the kit's lens and other A gear.

Back to the Tamron, I love the sharpness and color, almost like prime quality as in my FA 50 f/1.4. But I prefer lighter weight in that focal range. I know I am nuts in selling it instead of SMC FA 28-105 but I like the natural color and contrast from the SMC gear. I love the SMC FA 28-105 for its lightweight, color but it can never rival the Tamron for sharpness, especially wide open.

Heather, thanks for sharing the link. Please note that this is the poor man's choice for DA * 50-135. If you are interested, please take note on all the caveats that go with the poor man's choice as compared to the real gem as in DA * 50-135, few listed here besides what I posted in my blog with my initial impressions
  • It is all manual lens
  • Though constant at f/4.0 and sharp wide open, it is no where near as good as f/2.8 wide open -- you get what you paid for.
  • No 'A' aperture, all metering in Av with Ev compensation or M mode with shutter adjustment
  • Well built but lens is about 615g/21.7oz vs 24.? oz in the DA * 50-135
  • Lens is big and bulky but well balanced in actual shooting
  • On actual shooting with two hands, the 1 touch zoom works great though
  • The best is in the fast zooming and focusing -- very loose focus ring comes as a plus for me
  • Zooom falls to the front end making it uncomfortable to carry, no zoom lock is a minus
  • Zoom is distorted in 45mm making it less likely to be a good zoom for landscape
  • Zoom is great for portrait and fast moving objects as in squirrel and moving kids
  • Zoom is a zoom and you can't expect prime quality in IQ, but close in my books
  • The manual focus can be as good as AF if you practice
  • Nothing beats the happiness in getting great photos from quality but inexpensive gear. The contrary is also true -- life sucks when your cheap gear don't match up your expectations.

Hin,

Whatever you do, please don't get rid of the Tamron. While I'm pretty happy with the Sigma 17-70 now, someday, I wouldn't mind having the Tamron/DA21 combination myself. For a zoom, the Tamron is an amazing lens.

No, I'm not planning on getting the 45-125, as I've got other priorities that are far ahead of it--like settling on a tele zoom, a dedicated macro, and at least a couple more primes.

Heather,

I have taken your advice and that from Peter in keeping both the Pentax K 45-125 f/4.0 and Tamron 28-75 f/2.8. Instead, I will line up the other zooms to sell, I am working on a road map to trim my lens, documented in my camera gear page, I have identified 13 lens/camera to sell/donate/gift to trim my gear

Hin's Camera Gear - Hin's Tech Corner

But I am still uncomfortable in selling three lens that are lower quality than the Tamron -- kit's lens, DA 50-200 and FA 28-105 f/3.2-4.5. I probably will phase them out one in stages with addition of quality gear to make the transition easier. I especially like the FA 28-105, followed by DA 50-200.

Thanks,
Hin

Hin,

In addition to the 21 + 28-75 combination, I've also thought about a 21 + 28-105/3.2-4.5 combination, as well, mainly because the 28-105 is half the weight of the 28-75.

Granted, besides the great IQ of the primes, one of the reasons I want to have a nice prime kit is for when I want to travel light, so based on that reasoning, what would be the point of getting the 28-105?

So, at the moment, I'm envisioning my kit looking like this:
Lightweight prime kit: 21, 43 (or DA35), and 70. If I don't get the DA35, then I would add a DFA 100 for macro.
Zooms: currently Sigma 17-70 + Sigma 100-300 UC. Especially if I don't get the DFA100, then the 100-300 could also go with the primes for whenever I need telephoto.
I might consider replacing the Sigma 17-70 with the DA17-70, if it's weathersealed, otherwise I'll eventually trade the Sigma for the 28-75. Depending on reviews and finances, I would also consider replacing the 100-300 with the DA55-300.

With some of these new lenses not even being out yet, it's hard to make any definite decisions, but I'm keeping my options open.

I just got the 28-105 myself as my travel lens instead of the tamron for the weight issue and used with the tamron 1.4 TC I think its a really good package along with my 10-17 and a fast prime to make up my travel kit

It is a tough choice for me to make. The SMC FA 28-105 f/3.2-4.5 is good walk around lens. It is light and compact like the kit's lens size. And the focal range is better than the kit's lens for walk around but I find it a bit soft when I use it on my K100D, especially at wide open aperture. The color, contrast and bokeh is quite nice on the lens. I actually like the results better with this lens when I use it in my film camera Pentax pz-1. In a 4x6 print, sharpness is totally an non-issue and the color beats that of Tamron when I tried out the 1st film roll. I am on a road map to trim my current gear.

The f/4.0-5.6 version seems to come from Tamron. From what I gather, both are nice but people seem to praise about the Pentax version with f/3.2-4.5 more especially in the film era. When I use it with my Pentax pz-1, that lens perform quite well for me. I am sure yours will do well as well. That focal range in 28-105 will work extremely well to pair with a 21mm limited as Heather suggested. I pair it with Tokina 19-35 f/3.5-4.5 and a cheap prime in 24mm f/2.8 in outing and the combination of 2 or 3 lens has made my trip very pleasant for photo opportunities.
