16-50 is the worst product what can be bought used.
I see regularily these on ebay sold "as is". SDM motor failure (Search google for this) and couple of other problems.

I tried Formatt resin filters, but sticked with screw on filters (I guess was lazy to adopt to different aproach, placing plates into holder, etc). But it might be good aproache, see price for these filters from excellent Pentaxian (in the middle of page): About the Photographer : Transient Light |

David,
You need to decide for one of these:
B+W 77mm 3.0 ND MRC 110M Filter 66-1066186 B&H Photo Video
hoya nd 400 | B&H Photo Video
Where Hoya is little less dark, although in normal daylight or evening light one can`t see through filter. But autofocus is working. And live view produces some picture for composing.
B&W is complete blackness and allows to take photos for tens of seconds at daylight (with stopped down to some F10).
Hoya is better quality by means of sharpness and colors.
B&W produces brown/warm color cast to pictures, makes noticable wigneting on corners.
I have both (and couple of other big stoppers too) but prefer B&W.
In process of photography remember to take with you hat on head. After shutter is pressed I take my black hat of the head and put on camera. Just end of lens stays exposed to scenery. It`s because some ghost lights gets into camera through viewfinder and makes picture noticable less contrasty than with my black hat approach.
Worth to read: Tiffen launches 10-stop ND range to prevent red-tinted long exposures: Digital Photography Review I might jump for 10-stopper of tiffen, to test it`s colar cast or absence.

Take that polish review with slight grain of salt. They are biased and there was disscusions time ago.
In general - I like Marumi design (they are like slim filters, but has thread on front of filter). But real nature pictures looks better with expencive Helipoan - tones of colors somehow seems much better than Marumi, Tiffen and Hoya.
Tiffen is the ugliest option to chose from. I compared couple of filters on DFA 50mm/F2.8 macro At something like F5.6 and noticed huge decrease of sharpness with tiffen polarisers. For sharpness issue the best seemed Hoya polariser (HMC coating) and almost the same all others - B&W, Heliopan, marumi.
But then I bought Tiffen HT series filters (they made new series after some reviews where they got general bash) and seems they are in line with others.
So, Tiffen HT (Metallic titanium ring) is godd option. I decided to buy it, because I like to take sea pictures, and there is sand, dirt, water. They promises super hard and scratch resistant coating - so I believed them and have even more filters than anybody can imagine. :D

Cheaper modification of K-3 with the same count of pixels. And option to chose much more color options, even ordering your own rainbow colored k-300.

I compared Pentax 645 A 120mm and Pentax 645 FA 120mm against Voigtlander 125mm APO Lanthar (best macro ever). My point was to sell Voigtlander. For comparison purposes I used K---> 645 adapter and Pentax K-30. My comparison made confidence for me (that I can sell Voigtlander!) and it convinced my customer, who saw that Voigtlander is sharper than Pentax 645 format macro lenses and slightly more contrasty. But that difference was really small.
Besides - FA 120mm was slightly sharper than A 120mm
So, I assume Kolor-Pikker has bad copy. Or made some mistake at focusing (trusting to AF, or green confirmation light, etc?)

Please!
Don`t do this... don`t take weddings!
p.s. Question and samples clearly ilustrates what Imants couple of years ago told (Imants: fototrio.lv ): "It would be advisable to catch some of wedding pohotgraphers and just cut off their fingers. Only way to save couples from ruined memories of that day."
But Imants is far away, so, solution:
1. Use flash in manual mode. Most pros do so. Real pro shooters use flash in manual mode. Half pros use:
2. Compensation. P-ttl measures everything as 18% (it is 18% left from pure white, what is 100%). So, if it sees white dress, and flash reflects especcially active from that white dress, camera compensates everything to be as 18% gray. So, you can add +2 or more, and get almost ok pic. Or you can set up manual settings, let`s say shutter 1/150 and F5.6, leaving camera at ISO 400 (fixed). Take test shot, check out if everything is iluminated okay (histogram is spread evenly). If it is too dark, then open F, rise ISO. etc.
3. Use auto flash function (I don`t have Metz, but that function might be there).
The best what you can do - buy couple more of flashes and use all of them wirelessly at manual mode. Take them on tripods, place where needed (some of full juice against white roof) some in angle from som side, to add glamurous contours, some with white umbrella to make evenly light on subject`s front) and you will know how these acts and what power gives at that place where they are placed. Always the same result.
But from samples provided - better would be to chose axe against fingers!
;)

I agree!
But if he buy laptop for specific needs, he will buy that laptop with specific features. And IPS screen is quite popular with last expencive models - Dell XPS, Samsung 7 and 9 ATIV, Asus has a lot of IPS models - UX31A, UX21A, UX51 and super resolution screens like UX301LA. Besides Sony and Acer had also IPS models (but I don`t like their bussiness approach and personal experience - dnt`t remember exact models).
Yep, laptop ventilation system gets dusty over time.
So, I clean it!
I take my 2,5kw powerful vacuum cleaner and add to vacuum tube sturdy plastic coctail straw (i just glue it with scotch). So, I get powerful and thin vacuum straw and with this I clean ventilation of laptop (of course I open laptop) and PC too.
But I am UX31A user, that Ultrabook is all the time in my bed, under bed and so on (for one year) and I don`t have feeling that it needs to be cleaned.
One more point - It is reasonable to buy working laptop on ebay - used.
Because what usually happens to laptops:
1. It falls from your bed.
2. Somebody kicks it form table by messing with charger wire.
3. Coffee spill on keybord kills it
4. It is stolen or forgoten in bar, train, airport.
5. Something goes wrong with it.
So, it is quite little possibility that laptop will need warranty. Usually it has problem where warranty can`t help. So, I am buying my laptops on e-bay (have bought more than five - infulenced other people too) for cheaper price and I am happy!

Because ebay fees is drastic!
Ebay takes 10% from earned sale. And paypall fee is 4-5% for whole transaction. Usually 5% (for me), because purchasers is from other financial zones.

Na Horuk,
Sorry, but your points is totally wrong. Laptops has IPS screens nowadays, they are 1cm thick, and they use ivybridge/haswell porcessor +ssd. No noise no heat. Just little bit warmer than swithced off.
Said this, I always use 30 inch monitor and super-hardcore 32gb RAM PC for photo editing. But I like to participati in some photo things "on the fly", so - slim and small laptop with lightroom on it is really good for this!

For me all this is bad sign. They are beating dead horse and found a way to make it jump one more time - changing some paint on glass and body.
