DA*60-250 Vs Tamron 70-200 f2.8

Hi

Anyone care to explain the main diferences besides f2.8 vs f4 on those lens?

Maybe someone could compare them ?

Thanks

Sometimes a little google is all you need... specs can be found on the respective manufaturer sites or maybe even in our lens database.

The pentax his a larger range (extra 10mm on the wide end and an extra 50mm on the long end), it is weather sealed, it has an SDM (supersonic drive motor) which means that focusing is silent.

The tamron does not extend while zooming in and out (the pentax does), the focusing is noisier but probably faster (SDM lenses are no speed demons)

I think that one to one comparisons are hard to find, not many of us have these lenses at hand. I own the Tamron and i love it. I find it focuses quicker on the K20 than on the K10. IQ is great, very sharp even wide open.

I find the zoom range very good for practical use. I don't need wider, nor longer. I use it mostly for portraiture, sometimes semi-candid. It's quite heavy and I think I would use it more if it were weather sealed.

Another plus for the Tamron imho is the option to use a teleconverter. I've used it with a Kenko 1.5 TC and am very pleased with the results.

Same opinion from me.
Forgot to say I have one Tamron 70-200 with tamron 1.4x adapter.

I was only wondering what this new Pentax lens has diferent/special from Tamron Seems "only" the weather sealing.

I know the diferences between them.
I forgot to say I own the tanrom.
I just don't understand why the excitment about the new pentax lens. It's F4, I would understand if it was f2.8

Seems "only good" diference is the weather seling.

The excitement is that the pentax lens lineup has been missing a true telezoom for some time (a big complaint for some) and it has finally been filled.

And a bigger range while being smaller and lighter, which is why it is f/4 instead of f/2.8.

The Sigma 100-300 is f/4 constant, as is the excellent Canon 70-200 L f4. Both of these lenses are very sharp and contrasty wide-open, and can be used at f/4 for anything. The 60-250 is reportedly the same, although we'll need to see more to know for sure.

A 60-250 f/2.8 would be very, very big and heavy. The f/4 gives you a somewhat smaller, less expensive lens with no IQ drop.

I see.
No point then on changing from tamron even because would lose the speed and when needed, tamron can be also stopped down

Well from Richard days reports the 60-250 is as sharp or sharper at f4 then the 70-200 is.

But here are a few as i see it

The 60-250 has fewer elements so it will be less flare prone,

it is lighter and smaller (meant i didn't have to get a new camera bag),

the tripod mount is nicer as it has notches at each 90 that will "lock" the collar when rotating it (from what i have read with the tamron you have to line it up),

67mm vs 77mm filters (Polarisers are cheaper when they are smaller),

the 60-250 has the polariser window in the lens hood (incidentally it uses the same lens hood as the 50-135, which means when space limited i can only take one hood)

Not having used the Tamron i cannot comment on the AF, but the 60-250 is fast and accurate on the K20D even when coupled with the Tamron 1.4 teleconverter.

And the biggest advantage for me, some of the stuff that i have shot that requires longer lenses i have found that 200 was too short and 300 too long, 250 is a good compromise and all indications show it is going to be a great focal length for me.
