Software & Accessories / Re: Lightroom 5 Plugin for focus points?

I'm pleased to note that this plugin is the exception to the too-good-to-be-true rule; well done that man.

Hi, I published a plugin for this recently, maybe you'll find it of interest.
http://www.lightroomfocuspointsplugin.com
It shows focus points for all all (post-2002) Canon DSLR and all Nikon DSLR. Currently needs Lightroom 5.

If this is legit and not just well-tailored click bait then you're about to become popular around here.

I just caught wind of the Schneider 50mm f/2.8 tilt-shift.  I'm not sure if I want more to use it or look at it, but either way I want one.

I'm tempted to say you're better off carrying additional batteries compared to trying to charge while outside.  Even if you were in the sun a full day, would you expect to recharge 1 or 2 batteries? 

Check out http://www.hahnel.ie/index.cfm?page=li-ionchargers&id=145&pId=145 - it'll charge 2 LP-E6's at once, comes with Euro and DC adapters, and can even charge USB devices.

That Cube would replace both LC-E6s and a USB charger neatly.  However the appeal of the solar device (and its internal battery) is that it should keep everything charged over the span of a day even if there isn't enough sun to fully charge its internal battery; I don't mind making up the difference on the train or at a hotel.

I appreciate all the questions, if this solar device is the wrong way to go we'll find out so I can plan differently.

I think you are right, I was just pointing out the limitation so you did not get surprised.

You might compare the price and weight versus the cost of carrying say 6-10 batteries too.  I doubt if you would be 10 batteries away from a recharge.  Just be wary of taking 10 of them on a aircraft, and never put them in checked luggage.  You can pickup cheap third party batteries when you get to Europe and toss them before heading back.

You might want a dual charger, they typically charge batteries one after the other, not at the same time, but you do not have to be watching for the charge to complete and then manually change the batteries when charged.  If you are using a grip with two batteries, its really worth while.

I appreciate the input!  I plan to employ three batteries for the camera; one in it, one charged, one in the bag being charged off the device.  I hear you about traveling with many of them, I've seen what they can do.  I should have my new 5D3 in my hands this time tomorrow to start gathering battery life data.

The other thing I get from this device is a USB port to charge everything else I plan to take, which is no small thing.  It might make a convenient sun shade as well given suitable support - I can tan under an incandescent lamp, so everything helps!

I'd take a grip but if I can charge one battery on the move then I expect I can do without it, and so gain the option of a slim bag for the camera and two lenses.

Plan to pay $$$, and it will likely take a fulld day to recharge a battery unless you have a high capacity solar panel.

True, and it is their 10W kit I like; I'd likely sell it on my return, and if I get half of what I paid then I regard it as cheap insurance against missing an opportunity because of a dead battery.

I have a friend who uses one to charge an accessory battery that he then uses to recharge his phone.  He says it works pretty well.  Sorry I can't be more specific but he is not reachable for a month or so (trekking in Asia). So perhaps charging the supplemental battery (about the size of a fist) and then using that battery to charge his phone offsets any voltage fluctuation.  But the output resembles a USB charger.  Will that work?

It would for everything except the camera; if I remember anything from school the stated input current to an LC-E6 amounts to about 21 watts which easily exceeds USB 2.0 and is borderline for USB 3.0.

Hi Jim.

I don't know of any solar monkey type device with its own battery that has any more than 5v USB output, but I am aware I don't know all the products! ;D

Cheers, Graham.

Hi Graham, thank you for the reply.  I looked at one of these because it appears to have the features necessary, viz 12V out from a battery and a USB port.  I'm not sure if it can deliver 12V and power the USB port simultaneously, but the Watson brand LP-E6 chargers from B&H have a USB port of their own.

I plan to take my tablet, my phone, a couple of those WD portable drives with the SD card slot and two LP-E6 chargers, one for a spare.  Given that I have better things to do there than screw around on the internet, I expect the camera will be the biggest load. 

The battery in solar charger at the link states 72 W·h against 13 W·h for an LP-E6 so even without any power input I should be able to recharge a camera battery three or four times?  That is only a reasonable guess at the efficiency of the process.

Long story short, it appears to me that it should keep me from looking for an outlet for at least a day at a time; I have no wish to be obliged to sit around waiting for something to charge!

Re #2:  Indoor sports.  There is never enough light.  I don't own one yet but I've tried one (and shot in gymnasia with even f/2.8 lenses) enough to want one.

So further to my plan to invade Europe I had a look for a charger I could lash to the back of a backpack; I've seen a couple which will put out 12V which is enough to run a travel charger for an LP-E6, all fine and dandy.

My question is:  Has anyone actually done this?  Is it worth the bother?  I don't mean for it to be my only means of charging batteries, but to lessen my need to find an outlet as much.

Photography Technique / Re: Rain umbrella holder for tripod?
« on: September 11, 2014, 11:40:18 PM »
I'd get a cheap light stand and cut bits off the top until I had an open hole I could drop the stem of the umbrella into.

Ok fine, it's true: I'd do that, but I'd get a machinist friend to spin a plastic bushing to make up the difference in diameter, I can't do anything the easy way.  ???

I always thought that bayonets were affixed instead of mounted.

They are, the command is typically "fix bayonets".  They're convenient for making a rifle into something front-heavy which rattles.

I firmly believe the Swiss Air Force can afford fancy high-visibility flares; if it wasn't for the randomness in the smoke trails I could be persuaded to think it was CGI from the way the light is so soft on the bottom of the aircraft.  It's a terrific shot, don't get me wrong.

Imagine how many photos you can lose at once with one of these!
