Long walk around zoom

I'm looking for a long, portable, walk-around zoom and I think the Sig 135-400 might be what I'm looking for (although something faster would be nice). I have a Bigma, and it's great, but I also want something thats a little more comforable to work with but that will still reach out there. I know the specs on this lens, but was hoping to get some first hand input from those of you that own one. Looking for info on I.Q., sharpness, handling ect. I'm also open to any other suggestions. Thanks for any info you can offer.

Tony

I use a sigma APO 70-200 f/2.8 EX DG with a 1.4 x TC

This gives a 100-300 F4.

As a walk around for wild life, I also use it quite often with flash since in the forrest, there is not enough light without flash, and the flash gives a great exposure for the subject, and everything behind the subject falls off into darkness as it will naturally underexpose

Lowell,
Thanks for the info. The speed is certainly attractive. Are you generally happy with the I.Q. with the TC? I've had less than stellar results from TCs and zooms in the past but a 300mm @ f-4 certainly sounds good.

Define Satisfaction ?

See the attached crop out of a shot from my *istD. Hand Held 1/350th, F/4.5, ISO 400 no flash for this shot.

I have found it quite good, and well worth the value.

I have a Sigma 135-400, and I almost hate to say this but it's still heavy.

I have walked around with it, but it isn't my choice lens for longer walks or hikes

I have a couple of light weight Tokina lenses which are among my first choices.
A Tokina 75-200mm f4.5-5.6, which I swear is smaller and lighter than the kit lens.
And a Tokina 70-210 f4-5.6, which is a little heavier but better built.

There at least was one for sale here

Team it together with that 1.4 x TC Lowell Goudge mentions and you might just have a decent powered light weight setup.

What does this weigh?

my sigma is 1270g plus 143g for the TC or a total of 1413 g (3 lbs 2 ounces for the non metric folks) Due to the lens weight, and the size (or lack of) of my *istD it seemed a little heavy, but the larger size of the K10D makes it a very comfortable walk around.

In my perspective, most good and reasonably fast telephotos (or zooms) will be at least 77mm in diameter, and all will probably weigh about the same.

Thanks Stu....that's just the kind of owner info I was looking for. I really want the 3-400 mm reach, but I don't need another lens that sits home too much becuse it's too heavy.

Lowell, one more question. Is this an old lens? When I went to Sigmas site they currently list this lens in a C or N mount only?

In today's terms, yes it is really old. Bought new in early 2004 to use on my then new *istD.

The lens is a full frame (35mm format) lens, and unlike the newer version does not have "macro", but I didn't buy it for macro.

I understand it has been discontinued for some time, but there have been a lot of posts in other threads where people have found them still available.

The last post I saw was someone complaining that the purchase price of a used one was higher than the selling price of the current C/N version. I guess they held thier value well, and lack of an equivalent offering from pentax has certainly not hert the re-sale market. Overall, as I said earlier, I have been pleased with the performance

Funny, but true. Looks like I need to look in the ''Previously Owned" market. Thanks.

There is also the Sigma 100-300 f4.0 EX DG, if you can find one. I was fortunate, and am finding it to be a stellar performer.

Thanks Alan...I just noticed this one last while doing a search. Looks like it will also fill the bill. The problem I'm finding ( should have been expected) is that everyone is out of stock on all the good, long, Pentax mount lenses!
The 100-300 is about the same lenth as my Bigma, but about a pound less weight. Do you find it much of a problem as a walkaround lens and do you have any problems shooting it hand-held?
