Thanks for sharing, splendid shots! And very inspiring for using different angle as a way to represent experience of feeling inside. It looks like moving by a finger can have a dramatic effect on composition. You are correct about use of sides and corner that is always a challenge here! To me your series is a great way to train the eyes on how various types of shots change everything. I probably will keep them for reference in my own training.

Was actually considering the 16mm so it's very timely (I have used the 17mm but found a bit of limitations with light in the viewfinder, even if it's still a mighty little lens with incredible punch for its size). The result you are able to produce speaks loudly!

Dear Peng,

I would be interested in your 35mm f3.5. Unfortunately I cannot send you a private message. Can you do that and let me know how to arrange payment and other things?

Dear Lenny,

Sorry to post publicly, it seems that I cannot send you a private message (I'm on pentaxforum but only new to pentaxuser, hence there is a probabion period).

I wanted to check if you are still selling the A28 f2? Also the 100mm Macro 2.8 is interesting, more a specialty, but I think it might be above my budget anyway.

Dear Bai,

Quick question: Would you prefer us to make you offer through eBay, or in another way? Since I noticed you offer a different offer to us on this forum I wanted to ask you first depending on what's most convenient.

BTW Thank you for proposing other pentaxians to benefit from such a collection!
Personally I have been using a unique lens for 15 years (K50/1.2 on a ME bought so long ago with some luck). This lens never stopped fascinating me. After all these years, I am looking for a solid companion in the ultra wide angle. Unfortunately my budget it tight and it seems my first offer (in eBay) for the K28/2 was too low.

Thanks anyway, and I hope I can find a way to come back to you with a better offer before it's gone.

Best, -- Augustin
