Great ideas for recommendations.

Unfortunately I do a considerable amount of travel to the other side of the pond. The airline restrictions there are through the roof; completely unacceptable. One is forced to make all kinds of compromises in the types of equipment one can carry in a gadget bag/rucksack. Even then, one typically is not permitted ANY version of a tripod in carry-on; one must gamble and place it in stowed luggage - where despite the levels of security - it frequently just disappears

I've tried variations of the Sigma 300mm f2.8 ... By itself it's an incredible lens; both the optics (especially the optics because it's naturally a fixed focal length) and also the added benefit of the aperture. Add any teleconverter and the optics are almost as bad as a LensBaby on the wrong settings.

For most of the Pentax camera bodies and also most of the telephoto lens options; it's best to max out the mp settings (preferably going with raw+jpeg) and then even crop later. The cropping factor compared to the teleconverter still generally presents a better image just with the cropping.

[quoteI also find the WB a bit awkward to get right on aerial images][/quote]This brings up a few questions for myself...

1. Have you noticed it with just one lens or a variety of lenses?
2. Since I use filters myself; do you happen to use filters as well?
3. Since you mentioned aerial; I'm assuming they were taken from an aerial platform such as (perhaps) a private plane.

In reference to item three; and to the general audience. I would strongly suggest that anyone ever shooting photographs from items such as: a plane, a boat, even a vehicle in general... To make sure to turn off any and all forms of SR/image stabilization. Cannot begin to mention how many cameras I've seen damaged by this

Was just stating number and all for everyone to use.

Memory cards are readily available at both 256gb and even 512gb. Models released next year will easily be into the 1tb ranges. Unfortunately as it may read; over one half of all prefab (already made ones such as Dell, HP, Apple, etc...) still have mechanical drives.

Trying to sync one of those memory cards listed above to a mechanical drive would almost spell failure

I have tried ALL of the current FA's out on film cameras such as the: Pentax LX, Pentax MX, and even a Ricoh PK body. They all work perfectly.

Too bad there are not more FA lenses on the market. Even if they had to have a minor redesigning of outdated lenses

I'm not sure where Pentax went wrong with the mirrorless concept, but I am also NOT guessing when I clearly state it's also most likely not the end of the series for that particular camera.

Let me be a bit more specific about what I know up to this point. We're not stating anything relating to the Q branding.

That there may very well be a follow up to the mirrorless K-01, with a considerably better sensor - perhaps even better than the existing K3 sensor. Add on hardware could offer the possibility of a type of viewfinder. The camera would basically be a mirrorless version of the K3; focusing abilities and all.

Some industry insiders are also not mixing words by stating that (outside of items such as the medium format line) that Pentax/Ricoh are still placing considerable weight (and money) into the options of a full frame digital; at a rather interesting price point

Although the original post was a bit dated, and the person is most likely already back from the vacation and all...

The original post was missing the camera type. If it might be a camera such as one of the K3 variations; that camera body (and others) offer one the ability to mirror the memory cards.

But in case ones camera does not offer the internal hardware ability to mirror the memory cards; companies such as Sony do "occasionally" offer memory cards that do the mirroring themselves.


Not sure if this is worthy of a topic start on this next one, but also remember this gravely critical point. If one still happens to have a mechanical platter hard disk on their computer; one should never use any memory card that goes anywhere near half the capacity of that mechanical hard drive. The computer would most likely have large scale issues with near continual crashes; most likely trying to defrag a hard drive

One also has to remember how much most flash units break down, and how fast they do so.

I have many lenses still in use far before autofocus was available; some of the manual focus PK's. Most lenses last an incredibly long time in cared for properly, and can even be easily repaired. I rarely have used even a higher end flash unit, using it for professional work - and had it last much more than one year

@ Gabster...

By legal and contract law definitions... One does not need a model release IF it is a photograph of an adult taken at a public venue. Further meaning; if the subject happens to be out in public; ie - on the street, at a public park, outdoors at a café, etc... Not my interpretation, that's simply the way that it is written.

Take one at a public venue, most publishers do not require the release. Further case in point; just for purposes of example, not a literal example... Could be published in Life magazine, The Guardian, etc... Could be used for general story, editorial, or even most forms of commercial use

One of Pentax's best lenses. A bit of a limited zoom range.

One of the best items besides the optics, it's also the best WR lens in PK
