weddings sigma 17-50 vs sigma 10-20 + DA35

Here's my dilemma (another one )

I'm getting more and more into wedding photography (I used to use a tamron 17-50 f/2.8, a F50 f1.7 and a F70-210). The Tamron is gone, I'm keeping the F50 f1.7 for low light conditions and because I love this lens..., and the F70-210 will stay in the bag as a back up)

I'm buying a DA*50-135mm. I do not feel I need longer than 135mm for weddings. So here I am, covered from 50mm up... (and I'm using a k-5 and a K-x)

My question is: what do I get for under 50mm?

I have 2 ideas:

Sigma 10-20mm f/3.5 EX DC HSM along with a DA 35 f/2.4
Sigma 17-50mm f/2.8 EX DC OS HSM

The pentax 16-50 is just too expensive

The 2 different options would ended up costing me about the same price. I'd love to be able to go under 15mm for environment images BUT I would loose flexibility between 20mm and 50mm... Getting the 17-50mm would give me the peace of mind of not having to switch lens. Hummm. I don't know...

Any other options on how to gear up to complement my DA50-135 for weddings would be very much appreciated.


PS: LOVE this site, couldn't live without it. THANKS.

Why not get another Tamron 17-50? The Sigma doesn't have the best border quality wide open, and you're likely to be using f2.8 a lot in wedding venues. The 10-20 + 35mm idea isn't one I'd go for.

G'day. Interested to know why the Tamron 17-50 is gone - it's well suited for weddings being relatively compact, fast and with very decent image quality. The Sigma 17-50 would be comparable to the Tamron, but the Sigma 10-20 is too wide (with too much distortion) to be used as a group photo lens. Your budget of less than the cost of a Pentax DA* 16-50 makes the Tamron or Sigma 17-50 the most logical choice perhaps paired with a DA 15 ltd for the ultra-wide group/venue images. I wouldn't have the 10-20 on its own - and it's just not fast enough for photos on the move (would require a tripod for much of the time indoors).

The Tamron is great except at f2.8 (softness) and it's LOUD in churches (like bad). According to tests and review the sigma is quieter and actually more consistent with shapness wide open and across the frame.

There is no dilemma. The 17-50 should be taking all the main photos. The 50-135 would also get some heavy use. A 10-20 should only come out once in a while and only for specific shots that you have decided on before the wedding.

i am a bit shocked at the number of people who think a 10-20 lens can be used a lot in a wedding. at 10mm a wide angle can result in very unpleasant distortions with distorted skulls and other distortions. Even if you are doing it for free the people the couple if they don't divorce will be looking at the photos for decades to come.

In general my clients like the careful use of my 10mm fisheye which I only use for certain kind of photos. I have had negative comments about 10mm wide angle and I have deleted a lot of 10mm wide angles that clients never saw due to distortion.

My opinion is that you need
17-50 (I think the sigma is the best option)
I would go the 35Ltd macro so you can do rings and flowers

Your flash gear and flash technique is also essential.

My setup is probably anything but normal. Nearly everything is done on manual including the flash. I have a large flash bracket and the flash has a large softbox. Looks weird but is works for me.

Thanks everybody. Speaking of flash gear, I've been using two AF280t so far, bouncing on walls and ceiling or using them for filling purpose while stopping down a bit. Any advice on what my next flash should be (again for wedding work...)? I've been looking at metz flashes. They seem to be good....?

Just get something that is powerful and works fully in manual. I have about 5 sigma flashes and one pentax. ( I destroy flash guns and have had up to 4 being repaired) In theory the twin flash of the metz should work. I had a twin flash with my film kit that was great. However, while I trusted TTL flash on film, it does not meet my expectations with digital.

The power is needed for bounce, but you need a plan B when there is nothing to bounce off or the surface will provide a colour cast or does other strange things with the light. A very low ceiling can also be a disaster.
