Sigma 17-50 or 17-70 - Which would you choose

SAABas · 06-30-2018, 12:13 PM

Hello

I'm also thinking about changing the KIT lens.

Thanks to everyone for their thoughts. I am now the owner of a Sigma 17-50 that came up for a very good price on eBay. I haven't had a chance to really test it yet due to the totally uninspiring Ballarat weather at the moment but hopefully will get a chance this weekend. It is so quiet compared to the 18-55 kit lens that I have and the weight seems to balance the K3 just nicely.

it's a good pick.

You should be very happy with extraordinary clean and sharp pics. At 2.4 and 50 mm , you can do really good bokeh portraits. Only downside of this lens is size, but if you need good quality files beyond ordinary - its a real deal.

I can tell you one more downside, but you will experienced this only in rooms. when you have some straight wall in a front of, and in a frame. Distrprtion is visible mostly at 17-24 mm, but longer is Ok.
You can notice on walls - they can be strongly curved out of centre, because this lens does not have support from Pentax, and you can't turn on lens distortion correction.

So you will have to manage this in LR when it occurs, or when it will be bothering you...

But yet,. this a great versatile lens for highly professional work

You made a great choice. I just picked up one myself and have been very pleased with it. I lent it to a friend for use at a party and even with full auto on the KP, she got some great shots with it.

I do like 17-70 macro, very sharp on 70mm before like 11f, I shoot bumblebees and butterflies with it, can get around 1cm close to focus

I bought a used Sigma 17-50 / 2.8. Let's see how much better it is than a KIT lens
