Bits and Pieces 12-19 (Pentax Related or Not)

1. First of all, here comes the new patent of Nikon's "silicon film", i.e., a digital back for old analogue film cameras, but which is yet a vapourised ware that has never come true, since it was first announced back to 1999.

My suggestion is NOT to upload photos to Instagram unless you are willing to LOSE the ownership of your photos! >:-|

Btw, I don't know if Facebook will change to a similar new set of terms shortly. By that time if that happens, I am afraid that we have to delete our facebook accounts so as to save our copyrights! :-o

3. Sigma has market a new 18-250 in K-mount with HSM and OS built-in:-

4. An old YouTube demo on the sturdiness of the Pentax SP coating and how easy it can be cleaned:-

Well, whilst I do agree that the SP is easy to clean and it is very sturdy, I found that it is also a bit more shiny when it is compared to traditional SMC coatings on the front glasses. Thus, more light could be lost and it should be a trade-off after all. :-(
