Pentax 55-300mm versus Sigma 70-300mm DG APO Macro

Here's the price from Hong Kong (excluding shipping to the Philippines):

Pentax 55-300mm, USD 330
Sigma 70-300mm DG APO Macro, USD 173

Is the Pentax worth twice as much as the Sigma? I've read of the Pentax's very good IQ even at 300mm but is it that significant over the Sigma's?

Thanks!

the sigma isn't so bad if you can find a good copy. supposedly it's not as sharp at the Tamron 70-300 which has more Purple Fringing.
i have the 55-300 and i think it's great. being able go down to 55mm is really useful

just take a look at some of the posts here about the 55-300 using a search

I have the Tamron 70-300 di, and yes it can show ALLOT of purple fringing on high contrast edges. I need to remember to stop down when in high contrast situations. I have also learnt to use software to remove the residual purple.

But remember it is a $200.00 lens. And, for that price I enjoy a sharp lens with a macro setting. Overall, I am very happy with it.

I had a look at the Sigma 70-300 APO, but I felt it was softer then the Tamron, but it is not nearly as prone to the CA as the Tamron. I chose sharp with CA over softer and no CA.

There is a thread some where on this site that compaires the Tamron to the Pentax 55-300. And the Pentax is a much better looking lens. It looked to be sharper then the Tamron.

If I had the cash, I would have gone for the Pentax, and a macro lens. But, my funds are limited, and I felt the Tamron would be better then nothing.

For what its worth, I hope this helps.

Short answer, yes it is significant over the Sigma, and worth even more than the asking price; its a bargain.

I've had all three - Sigma APO, Tamron (both LD and Di) and DA55-300.

The Pentax is fundamentally and unequivocally the best of the bunch, it's probably one of Pentax's best efforts in the affordable sector for many years.

Does the Pentax DA 55-300mm lens have internal focusing (IF)? Couldn't find mention in the literature or specs.

No, it extends when focussing close, but the front doesn't rotate so the use of polarisers is practical, whereas the Sigma and Tamron both have rotating fronts.

I have the smc PENTAX DA 18-55mm F3.5-5.6 AL WR
and the smc PENTAX DA 50-200mm F4-5.6 ED WR for my K20D.
I would like to have a 300mm lens that is weather-resistant since i live in Northwest Oregon and we get a lot of rain.
Is pentax planning to release a smc DA 50 or 55-300 ED WR ?

I've owned both these lenses and the Pentax is a much better lens.

The sigma has the close focus advantage though.

But I agree with Richard Day, the Pentax 55-300 is worth more than they are asking for it, its very good. So good I'm KEEPING MINE! :P

You've asked this in another thread.
There is no way of really knowing, but as usual, ogl looked into his crystal ball and made his predictions. Take them at face value.

I have the 55-300 and have posted plenty of landscape photos using it. I love the lens but I really wish it had a macro ability. Due to the wet weather up here, I'll probably pick up a WR if its ever released. Hopefully they produce a version with macro.

Get a Raynox 150 or other good quality closeup lens for use with the 55-300 and you've got all the macro capability you need.
