I just got the news from Ebay: the super cheap K-7/K-5 Alpha Digital battery grip has been shipped.
It is the cheap variant with the plastic pins, nevertheless i had to pay it a small fortune... € 29.99 shipment included!
I've used with full satisfaction an equally cheap battery grip for my K200D. It is a camera which is quite picky about batteries: i have seen rechargeable AA batteries, and even brand name conventional alkalines, causing strange problems. Lithium batteries are safe, but are also expensive and not easy to find.
I purchased two sets of Eneloop, for the camera and the grip, and all poblems were gone!
With that in mind, the first thing i've done after buying an almost new K-5 II, was to buy a battery grip on Ebay.
I purchased a couple of D-Li90 batteries too (one is a 1600mA, the other a 2000 mA, the original Pentax is 1860 mA), but i guess i will often use the grip with AA batteries.
I am going to leave for a long journey in South East Asia, and i want to be able to shoot with readily available batteries, if there is no electricity or the charger goes bust.
I hope the new super-cheap battery grip will serve my K-5 II as well, as the old one has served the K200.
As long as the buttons don't fall down, or get stuck, i don't see any other source of major problems. Or, at least, nothing that a little of "dry" contact cleaner can't cure...
I found this thread after the purchase, so i didn't pay attention to which "type" of grip i was going to buy. I simply went for the cheapest.
After reading a good number of posts, what impressed me the most were not the technicalities, but the words used by a few advocates of the "always buy Pentax" school.
I thought that words like "steal", "rip-off", "crime", and other amenities, would never find their way in such a discussion. I was wrong, there is always the improvised lawyer who repeats, parrot-like, badly digested concepts, like those spread by corporate propaganda.
A non-Pentax grip is no different from the thousands of third-party car spare parts which are sold in any corner of the world.
The cheap grips are not even identical, but marginally different, while some spare parts, even complicate and expensive ones, are often IDENTICAL, because made by the SAME company in the same plant. Just a different sticker, that's all.
If the automotive industries are not going to court, it's because it's not feasible.
Please, leave the word "crime" where it belongs. An example: the criminal behavior of two giant pharmaceutical multinationals who badmouthed an equivalent product, five time cheaper, spreading false allegations. The italian regulation body got hooked, and the equivalent product banned from the public system. Fortunately the two companies got the biggest fine to date, from the italian antitrust... the reason they got screwed is just because they were so sluggish to exchange emails where they explained in details their plan!
There are many highly ethical things we can do, voting with our wallet.
I don't think that buying a Pentax branded grip is one of them, i am sorry....
cheers
