Hello there

I've seen a lot of posts re. the sharpness of the mythical pentax 60-250 - and none had images on.
I also went to SRS the other day, and I made sure to try all the lenses on MY camera rather than the ones on display, so that I could find some results at home...

This is NOT a scientific test - the benchmark is the very reliable sign across the road from SRS - and the shots are all handheld, from marginally different positions, inside the shop.

I will post 4 photos per lens - at minimum and maximum focal lenght - I couldn't shoot at all f-stops, and tried to get results at the widest possible - because this was my interest.

Planning to buy a telephoto I tried these 3 lenses. My comments are in another post where I described my feelings re the 60-250 - so no need to repeat here.

I must say that although I am not posting photos here, the most impressive lens I have tried in the last 3 years is definitely the DA* 300 mm - this is incredibly sharp, and absolutely stunning IQ -

And now, lets get going.


Pentax 60-250 f4 - PRE-PRODUCTION

Pentax 60-250 - 60mm f5.6 1/125 -



Pentax 60-250 - 60mm f5.6 1/125 - 100% crop




I didn't shoot at 250mm and f4 cause the results were aweful - I looked for sharpness, and honestly, this is the best I could get.


Pentax 60-250 - 250mm - f14 - 1/50 - holding onto something -



Pentax 60-250 - 250mm - f14 - 1/50 - 100% crop holding onto something -



And now the 50-135 f2.8

Pentax 50-135 - 50mm - f3.5 - 1/500 -



Pentax 50-135 - 50mm - f3.5 - 1/500 - 100% crop



Pentax 50-135 - 135mm - f2.8 - 1/500 -



Pentax 50-135 - 135mm - f2.8 - 1/500 - 100% Crop




And finally, the Tamron 70-200 f2.8

Tamron 70-200 - 70mm - f2.8 - 1/500 -



Tamron 70-200 - 70mm - f2.8 - 1/500 -100% Crop



Tamron 70-200 - 200mm - f2.8 - 1/500 -



Tamron 70-200 - 200mm - f2.8 - 1/500 -100% Crop




Tamron 70-200 - 200mm - f7.1 (sweet...) - 1/100 -



Tamron 70-200 - 200mm - f7.1 (sweet...) - 1/100 - 100% Crop





I am planning to buy the Tamron, mainy because its longer than the 50-135, and seems to be very very close in IQ - the results at f2.8 are incredible IMO - and the sharpness stopped down make it a real competitor in this market. And the price......

I wonder how much better than the pre-production the 60-250 real samples will be. I will not be considering this lens because of its extending barrel, F4, IQ, but mainly, price.

Hope this helps,

Nathan

I will back those findings, my 70-200mm Tammy is really very good and if you want it, it will autofocus with a Kenko 1.5 TC.
All I want now is better weather, so I can get out to use it.

The DA*300 really is special. It is definitely a must have, even at the high price it has.
