K-1 to K-1 mkII upgrade service available

Trading in a good condition K-1 for a brand new K-1ii doesn't cost that much more (with SRS UK, at least) and you get a brand new warranty to go with your brand new camera...you'd possibly do even better selling privately first.

The major issue here for me is this...yet again the presence of water damage is used as an excuse not to honour the warranty, but the possibility of faulty seals has not been mentioned.

The seals are an integral part of the product - part of what you PAY for. If a seal fails through workmanship or materials faults, that is a failure of the product and the fault (and subsequent damage) should be rectified. It is like a faulty battery causing a fire and then the company refusing to fix the problem, because fire damage is not covered...and then forum members rush to their defence saying the user must have put a match to it.

I can't really see for sure from the image, but it sure looks like it could be fungal etching...or indeed fluff/hair. The fact that it doesn't move is worrying.

If it was in the middle of writing to the card when it lost power then it has quite possibly caused a corruption to the file table. Basic file recovery should find the data.

K-1mk3 what if...

Ha ha...really? Then it should be a simple matter of phoning Sony and asking them to design and build one just for you and you can swap it out yourself.

In the real world, they make sensors that they think there will be demand for, then offer them for sale by the thousand. There is precisely zero hope of them dropping millions in design and development because Pentax asks them for 10 of them.

Justification for the Pentax 20-40 Limited, compared to 18 50 HD
Posted By victormeldrew
Replies: 29

Personally, I would say that the strengths of the 20-40 lie in different areas to those in these samples. It is particularly good in contrasty scenes, and is particularly good into the light, and has a 3D separation that makes depth pop... These flat-light flat-field images are bread and butter for any competent lens. Prod it a little and it really shines where the kit lens won't...

Questions on Lightroom performance optimization

Different speed RAM modules will all run at the speed of the slowest. RAM speed is much less of a factor than RAM quantity when it comes to image editing since if you run short of RAM, the OS will use the page file which will (unless it is located on a fast SSD) be considerably slower than any RAM. So using it all is likely to improve performance somewhat, especially if you are RAM constrained at the moment...which is not necessarily the case, but without watching the performance monitor this is unknown.

Tripod as a Lightstand?
Posted By victormeldrew
Replies: 15
Views: 651
As long as your tripod can get your light where you want it, and won't get in the way in the process, no problem. Where lightstands have the advantage is their versatility in terms of positioning (the height and reach to get overhead a model for example) while not cluttering up the sightlines with legs (they usually have legs that can sit flat on the ground with only a single thin upright and boom rather than three chunky legs). If you're wanting to set up a three light rig around a model with tripods you will end up with a clutter of legs getting in the way and will struggle to get the overhead or hair light in place.

Crop Factor Conundrums
Posted By victormeldrew
Replies: 29

The simple way to think about it is this:
The same lens takes the same image regardless of the format it is mounted on. Everything is identical, light transfer, DoF, FoV, sharpness, everything. It is the lens that creates the image, the body only records it.

An APS-C body then simply crops the centre ~2/3 of the image and discards (never records) the rest. FF records it all. The only time that matters is if you were trying to capture the same image on two formats, which you aren't and won't ever unless you're very dull or seriously bored.

stitching photos tip

For working on large numbers of large files, a very large amount of RAM is required. 30 files at (let's say) 36MB each will be over 1GB. To process that, the software will need multiple copies of the data to ensure non-destructive editing. This then needs moving and processing. I would want at least 16GB RAM along with a very fast processor and HDD. Even then, long processing times are inevitable.

One solution is to downsize the images first - unless you want to end up with a 600MB file, you will be downsizing anyway - and work with smaller TIFFs to speed up the process.

Without a modifier, it could be anybody pressing a shutter for any reason. However, if you were at a wedding and asked "where is the photographer" you clearly don't mean the mother of the bride with the phone in her hand. So, with modification it is more meaningful:

Wedding Photographer
Press Photographer
Amateur Photographer

On its own then, the word is ambiguous at best, but with context it can mean any number of specific things - none of which define any particular level of quality, but let's not get too zen about it.

Buying after market lenses...wise or not ?
Posted By victormeldrew
Replies: 12

Some of my favourite lenses are 3rd party. I suppose that, with readily accessible online reviews and testing exposing flaws for everyone to see before they buy, it is less possible to drop substandard products on the market and hope for the best. There are some very good quality lenses out there, and some less-so but more affordable ones too...and you can find out which is which with a few clicks, no need to buy-and-pray.

If you limit yourself to only Pentax brand lenses, I'm afraid you will be rather restricted in your options if you want to buy new with warranty. When it comes to ultra-wide, you're out of luck (for now). When it comes to creative lenses like tilt-shifts and creative apertures, nothing available. When it comes to 'straight' zooms and primes in the wide to tele range you're pretty good, though.

Probably the exact reason why doing whatever it is you think they should do would be a hiding to nothing. When a very niche market is cornered by a massive player, why attempt to wade in and spend millions on R&D when you could only hope to gain a small share of a tiny pie?

There's a few reasons why they wouldn't/shouldn't. Their energy density is poor, the form factor is very inefficient being they don't tessalate, people dislike having to purchase batteries having just spent a wedge on a device, then they go purchase them from a huge variety from alkaline to lithium, good to poor, leaving the engineer no control over the power source for their device. They often leak. Most of all, the manufacturer has no aftermarket income from replacements. All in all a lose/lose for them and if the only choice is heavy bulky AAs, not great for those that prefer small lightweight devices.

The 18650 cells available, are designed for very high current drain, which is why they are chosen by car builders, high-power flashlight builders, and vapers. The best of them can run at 25Amps from full to empty without a break (given proper venting and cooling). They are totally overkill for a camera whose demand would be best given in milliamps and that only sporadically with long periods of downtime. They also require external protection and are not particularly safe when not inside a device, so they would need to be built into a casing with protection, adding further cost in addition to the cell's cost. The resulting battery pack would be BIG...at minimum 70mmx20mm...which would then require more space each end for connections, venting and cooling. Which adds the final issue, the rate at which they vent gas during a fault requires large holes to the air, which would be incompatible with WR. These cells have been around a long time and all camera builders have avoided them so far, probably for these reasons and more. But voltage is not an issue, a high efficiency buck-boost regulator can up the voltage easily with all that current to spare.

Really, if more capacity is generally favoured despite added size and weight, the better solution is to add additional small cells to the battery pack.

Assuming you're not planning to spend car-sized budgets on the camera, the 645 is out. Assuming you want to buy new, that leaves 4 (if you're lucky) to choose from...or 3 if you want a current production model.

1) Least budget: K-70
2) Full Frame: K-1
3) Smallest/hippest: KP
or (if you can find one)
4) Best: K-3II (IMO)

Then choose a WR lens in the focal length range you like and you're done.
