It is often frustrating when the available telephoto is too short. But the 28-105 with a good sensor seems to perform reasonably as well as a medium quality lens of greater length. And it is much ...

I have been using the new 28-105 with my K-1 several months now, and I find the performance regarding sharpness remarkable. Some vignetting and CR is correctable with software. The latter should ...

I may add: The FS-128 was - in 1997 - sold at about 5000 Swiss Francs (equivalent of about 4500 Euros). The photo was taken when the moon was rather low over the horizon (28 degrees elevation). ...

It is a Takahashi FS 128 (128mm primary) bought some 20 years ago. It is a doublet with a Calcium fluoride lens element that enables near perfect correction of chromatic aberration. It is no ...

Just two photos taken last evening from my balcony with the K-1 at the focus of a Takahashi 1040mm f8.1 apo refractor: Moon. Contrast enhanced with "Topaz Clarity" The Pointe de Marcelly, some 30 ...

Nice. I would very much like to have the equivalent for Full Frame. We now have the 28-105 which performs very well - but a 28 (or 24) - 250 would be perfect as a travel lens with the K-1.

Does look like e-mail address harvesting....

Sneeze !!!   (I have hay fever...)

Sorry for what happened to you ! This is a world where profit and money is more important than a human life. I wish you the best for your future.

Well - I have been waiting for more than 30 years... with my A* lenses (200, 135 and 85 among others) for the K-1. And the K-1 offers all I have expected - and some! But, for those starting with ...

Some photos taken last Thursday with the K-1 and the "old" A*200 f2.8: The summit of the Mont Billiat with Lake of Geneva. Taken with a 28 - 105..... With the A*200: The Mont Blanc. At 56 km from ...

Well - that was in "olden times" when I was still earning some decent money. But, looking back some 35 years - it did turn out to be a good investment ! (glad I didn't get rid of them).

Yes, they have heavily invested in APS-C. But I have "historically" collected a number of high-end Pentax lenses of the "film era" (A* lenses such as the A*200 f2.8, A*135 f1.8, A*85 f1.4 among ...

Having passed the 3/4 century mark last year I can confirm the importance of remaining active to stay fit in old age. Some years ago, I joined a group of local hikers and every Thursday we go ...

Something I forgot to mention: you can improve astronomical images by stacking a number of successive images. Stacking reduces noise and improves definition. The moon image was a stack of 5 fast ...

I should add:  400m above sea level. 1/800" at ISO 800 with a 1040mm F:8.1 apochromatic Takahashi FS 128 f:8.1 refractor.

Good and clear sky. But excellent optics. An astronomical telescope designed to render the theoretical definition of its aperture. And a camera capable of taking advantage of such conditions.

Excellent for stars - but at their distance they still remain points of light. Excellent also for distant mountains - but very narrow usable field of about 1 degree (twice the diameter of the full ...

For some reason - Jupiter did not appear... here it is: Jupiter, with moons Ganymede, Io, Europe and Callisto - left to right (June 2, 2017 22h CET) 1" ISO 400
