Walk-around lens?

Hi!

Just got myself a k10d, body only, and now i need a walk around lens. I have been thinking about the sigma 18-50 2.8 ex dc macro. Does it communicate focal lengtht to the camera, so that the SR works properly?

I have also been thinking about the sigma 17-70, maybe combined with a fast prime, for low light situations. Is the 17-70 a lot worse (in terms of colour and IQ) than the 18-50? Some reviews and sample images seem to indicate that they are rather comparable. Some (photozone) even seem to think that the kit lens is just as good as the 17-70, at least in terms of resolution, maybe less so in terms of contrast.

What would you suggest?

Pretty much any K mount lens made in the past 25 years will have an "A" setting, and certainly any autofocus lens. I almost bought the Sigma 18-50 f/2.8, but found a DA 16-45 f/4 for a price I just couldn't pass up. I've been very happy with the 16-45. It is by far the best zoom I've ever used.

But don't discount using a prime as a walk-around lens. Many people (myself included) naturally gravitate toward a particular angle of view. In my case, I keep an FA 31/1.8 on my camera almost all the time. Anyway, something to think about.

The Sigma 18-50 & 17-70 both receive good reviews - I don't own the 18-50 so can't personally compare.

I can highly recommend the 17-70, I replaced my kit lens with it and am delighted.

The Pentax 16-45 & Sigma 17-70 seem by far the most popular zoom options & image quality seems about even, the 16-45 suffers a little more CA apparently. Ultimately I chose the 17-70 for its extra range.

Regarding primes, I don't do much indoor photography but recently bought a 50mm A 1.7 from Ebay - really is a great lens and cost very little. It's manual only but with the focus confirmation of the K10D its extremely easy to use

The Pentax 16-45 F4 lives on my K10D.

If i happen to be in a prime mood when i do a walk around, i usually throw on the A28 F2.8, as i don't have an FA 28, yet.

I used to have the kit lens 18-55 with my *DS; It was an excellent lens but it was abit slow. I shoot indoor a lot and that became quite a problem. Of course, I have a flash, but really..it's not the same.
So when i upgraded my *DS to K10D i picked the Sigma 17-70. Very nice lens. It gives me f2.8 at 17mm for indoor shooting, and the 7 reach works very well for portrait. Highly recommended. The lens feels very solid (heavy) and well balanced on the K10D, compared to the 18-55, which is very light, i would say a bit too light to convey a quality feel.
Of course, the 18-55 is underservedly cheap. It's very good for a kit lens. I would say that it worth more than what the going price, if Pentax didn't choose to kit (or is it the other way around... that everything else should be a little cheaper?)

The Pentax 16-45 F4
What's the appeal of this lens compared to the 18-50 f2.8 sigma?

I have my 50mm f/1.4 permanently attached to my camera. Not really, but I use it a lot.

I usually have the 50mm 1.4 as well on my camera a lot. From my experience the images are much sharper than the kit lense, granted you miss the ability to take shots at a wider angle, but I find the sharpness that much more of a benefit. Also, I really like shooting at 2.4-1.4 for some portriats outdoors. Makes for some crisp nice shots.

I am very happy with the 50mm and yes I occasionally use the kit lense when I need wide angle.

I tend to walk around with the FA 80-320 as well when going for outdoors walks etc. Its not to heavy and takes pretty good pics for a budget zoom.

The FA 50mm 1.4 is a great first addition in my opinion and at 180 or so its pretty cheap I think.

The 18-50 is handier in low light perhaps, but the 17-70 is a much more versatile range.

I believe a) you can never go too wide, and b) the odds of having the right lens for the shot is inversely proportional to the number of lenses you have.

I got so hooked on 24mm lenses with the MZ-S and 24-90, that anything that wouldn't go at least down to 16mm was not going to make the cut. I also found that I often wanted a bit more stretch at the wide end, so I ordered a kit with the 12-24 and waited and waited for the 16-50.

Now I'm happy. A pack horse, but I'm happy.

I've always been a sucker for a fast wide to normal prime lens, such as a 50/1.4 or 50/1.8(7), or a wider 35mm/28mm (the 50mm is ideal on a film body), generally the normal-ish range primes that were faster than 2.8 have usually been my main walk around type of lens.

I just picked up the 16-45 zoom lens, looking for a semi-replacement for my prime lenses in that range. I've found the images to be really sharp. It's a very good walk around lens that I use almost exclusively now as my 'main' lens. Indoors, when things get hard for F4, I bring in the external flash unit.

Primes are great lenses though. Might I recommend the DA 21? I have the DA40 Limited and it's great, but just not wide enough for me

A good walk-around lens depends on where you are walking. I've been using the 16-50 f2.8 for walking around town. The 50-135 f2.8 I've not used a lot yet but I have had it only a couple of weeks. I just bought an M 50 f1.7 to try out when I don't want the size and weight of the zooms or when I want to shoot in the dark. It may not be as good as a Noctilux (f1.0) but I think it'll do just fine.
