That's true, (very) old lenses often have a "soft" front element or coating so a filter takes care of that but now a days the front coatings are very tough so there is no need for the filter anymore. The front elements/coatings now are even tougher than the UV filter since the filter is only a thin piece of glass or plastic so don't expect much protection besides against corrosive materials.

The coatings on the lens already cuts the UV quite a bit and there is a filter also on the sensor that cuts it as well so to put a third filter on it to remove the UV sounds like an overkill to me.

The AF160 can't use p-ttl right, isn't it an idea to buy a wireless receivers for it?

From the prices i see on this page they don't cost a lot more...

But when you switch the camera to off it doesn't go off right away but keep on till it's finished so it's more like pressing the off button on your PC then that you pull the cord.

Yeah Amazon should be safe but you need to know a bit on how to use the SD card probably like formatting and such, for most not really a problem but you can get funky results

But most SD card comes with lifetime waranty so if you've problems getting a replacement often isn't a problem.

btw there is a new SDHC card from Sandisk called the Extreme Pro it is UHS-I(45MB/s)

Now only the focussing under thungsten...

Somehow i want to wait for the camera that will replace the K5 since now you see that the processor is slowing the camera down quite a bit... Hopefully they will also update the processor in the 645D since that one is even slower but that isn't a surprise.

Oh no i got that!

But there are also SDXC cards that have class 4 ratings for example and there will also be SDHC cards with the UHS rating as well so an SDHC card can also be too fast.
The UHS Rating/speed isn't limited to SDXC cards, that's what i was trying to say.

So all in all SDXC doesn't mean the cards are faster only that they are bigger then SDHC (the hardware and protocols are even the same between the two so only the name and size different).

ps. UHS speed cards are backwards compatible so it will work in the K5 and K7 but not at full speed.


This a SDHC card with an UHS-I rating for example.

Indeed but i would need to buy new flashes and a new camera... but it would be more future proof though!

And since many computers and smartphones has bleuthooth they should be able to make a "studio" program for it maybe

It's also no problem with the longer focal lengths since the angle it needs to create isn't that great it's the wide angle lenses that are the problem.
That's one reason why Pentax is first going to devellop new wide angle lenses for the 645D and then the longer lenses.

Don't stare to blind on brands, Dell for example don't make the actual panel themselves so no need to buy Dell for the screen since LG makes most of them for Dell.

Best screens for photography for a desktop computer would be MVA or PVA, those have the best contrast and colours (Eizo and NEC use them), IPS is better for bigger screens and laptop because they have a bigger viewing angle.
Avoid TN at all cost!

here is a good read about all the differned screen types.
They also have good reviews and you can search for the panels and not the screen themselves.

The Dell 2209WA for example...
Has this panel: 22"WS LG.Display e-IPS (LM220WE4-SLB1)
And these also have that panel LG W2220P & Fujitsu P22W-5 ECO
There are some things that will effect the quality of the images between the models but the result should get quite close to eachother.

Dell has some good cheap screens and if you look around a bit you will find some very good HP screens as well for a nice price.
