which one is going to be a more useful zoom range for events on an APS-C?

1. 16-50 f2.8

options of tamron/sigma/pentax SDM? (tamron and sigma being 17-50)


2. 24-70 f/2.8

option of sigma (the new one with HSM)

3. 28-75 f/2.8

options of tammy


4. 50-135/f2.8

options of pentax.

money is not the issue.

Thanks in advance for replies

If you need "overview" shots, you have to take the 16-50.
And since you almost always need "overview" shots the question is settled.

On the other hand, if you are sure that you do not need "overview" shots, then probably a 28-70 is more useful, it depends on what you mean by "events".

I'm sure everyone would want to know a bit more what kind of events are you going to shoot? I mean some events have to be shot from a distance (audience etc) and others you can shoot from closer distances.

edit: Wieland was quicker it seems

Define "overview shots"?

events? like family functions, kids birthday parties and friends get-to-gathers.

small gatherings to be covered as personal memoirs

What are you using now for it? 18-55? At which focal length mostly?

If all your shots are at around 50mm it does not matter too much, does it? If lots of them are below 24, draw your conclusions

For the given purpose, I would opt for the 16/17-50

All focal lengths between 16 and 135mm would be useful.
Such events at times require larger group shots that 16mm would barely even cover, but then again there are some times when trying to catch kids in their natural element requires stealth, and even 135mm may not be enough reach... so for the best of both world's I'd suggest at least two lenses - 16-50 and 50-135. Changing lenses may be an issue, but in my events, including weddings, I am prepared with a 12-24, a 28-75 and a 70-200/2.8 - that's 3 lenses, but basically covers 12-200mm, mostly at f/2.8 (can get away with f/4 for the 12-24 FLs).

I have both the DA* lenses and am very happy with those. If you don't want to switch lenses, you might want to consider a wider zoom range:

SMC PENTAX DA 17-70MM F4 AL [IF] SDM
SMC PENTAX-DA 18-135MM F3.5-5.6ED AL [IF] DC WR

Depends on what you shoot and how you shoot. + there is 100 photogs with hundred opinions. If money is not an issue, get combination of options 1 & 4 and you are sorted.

I have both 18-50mm & 24-70mm f2.8 Sigmas, from experience I can add
that between 18 and 20 mm's or so, any pics of people will most likely show
some distortions with a 18-50mm.

On the other hand, I find that 24mm is often just not wide enough
and barely use the 24-70mm anymore because of that.

I just use the 18-50mm and crop the final picture when I want
to 'zoom' into a subject, pic quality is not that important for my type of photography.

I guess it depends how far away you are from your subjects,
if possible using a 17-70mm f4 would avoid a lot of lens changing.

Your events may not be my events.

But when I step out, I usually have an 18-250 on my K20D. From overviews to pinpoint captures, it works. Indoors is another matter, and I stick to faster primes: 16/2.8, 24/2, 50/1.4, 85/2, 135/2.5.

You need to be clearer about your needs before we can give useful advise.

At the moment, this is the glass i have.

in AF

1. 18-55 f3.5/f5.6 (the infamous kit lens)

Vintage Manual Focus Glass

2. 28 f/2
3. 50 f/1.4
4. 58 /f1.4
5. 85/f1.4
6. 45-125 f/4

I like 45-125 but it is heavy, very large focus throw (needs too much time to focus), and has zoom creep. The picture is soft at the edges @ f/4 throughout the zoom range. Another downside of 45-125 is minimum focusing distance of 3 feet. Despite the negatives, whenever i get it to focus precisely, the picture is an absolute joy to watch.

the 58 and 85 are m42 lenses, converted to k-mount. Downside, I can focus at infinity. and I rarely use them.

At the moment, the lenses that find their way onto my camera are either the kit lens, or the fast 50.

When it comes to color, I dont like the colors of the kit lens, plus, i also dont like that its a slow lens. want something faster and want something in AF.

ATM I use the kit lens for events. Reluctant to use the 45-125 due its high minimum focusing distance.

My issues? Not the money, but availability. I am in Pakistan, and Pentax stuff is not available in Pakistan. Means no support.

With QC control issue, i am reluctant to go with either the 17-50 or 28-75 (although my research reveals lesser complaints of a bad copy in the 28-75 samples). Shipping bad copies all the way to US from Pakistan would be a problem.

Same goes with the SDM issue. I want to buy the 16-50 and 50-135 but i am affraid of the SDM issue.

How do i shoot? I love the 50 f/1.4, I shoot the 50 at around f/2.8 most of the times. When its the kit lens, its mostly at 35mm, variable apertures.

if sdm worries you then tamron 17-50 & sigma 50-150. if you need even longer reach then tamron 70-200mm would make a good addition.

2 bodies minimum are a must for event photography

If you simply don't want to go with an SDM lens, then you'll find the Tamrons giving you the best range and IQ for money. Their 17-50, 28-75 and 70-200 lenses are among the best in their class and most practical range of focal lengths.

Okey, I recently shot a wedding with two primes, M 50/1.4 and M 28/2.8. I loved the 28, with its normal fov, but missed the wider side. After giving much thought, I have decided to go with,

1. 16-50 sdm or sigma/tamron. (still not sure). Leaning towards pentax because I think it is safer to take risk with pentax, rather than qc issues of tamron/sigma.
2. 50-135 sdm.
3. 31 limited. (I liked 28 fov, but manual focus isn't my strong suites.).

Any comments. My bonus is due around may, and I think I will be able to afford all three.
