comment Hot-swapping batteries in a battery grip
Sure, all of the Pentax K-7. K-5, K-5 II, K-5 IIs, K-3, K-3 II DSLRs use that type of grip, although the actual model differs. For K-5 IIs for example takes the Pentax BG-4 grip which takes a Lithium-Ion battery or 6 AAs, in addition to using the Lithium-Ion one in the camera. Apparently this is more common in mirrorless cameras, both Olympus E-M1 and Fuji X-T1 for example use the same design.

comment Hot-swapping batteries in a battery grip
Sorry, reworded: Good. I would add the case where a grip works while a battery is still inside the camera, so you can hot-swap the battery or entire grip even.

comment Distortion Removal=Parallax Removal?
Ah, I think you are asking if we perform distortion correction, do we get new depth info. No, not really because the correction is 2D, so it does not generate new depth-info. If you have a depth-map though, then you would have to apply the same geometric processing to it too, so that it corresponds to the undistorted image.

comment Lack of clarity when my image is transferred from my DSLR to the PC! Its really disappointing
It's the same photo, so most likely you need to calibrate your screen or possibly get a new one, if the one you have isn't any good.

comment How do I choose a wide angle lens for my 700D?
There is a way out: Get the EF-S 10-18mm F/4.5-5.6 IS STM instead. It is ultra-wide and stabilized.

There appears to be something wrong, an 15-18mm lens would be a very very short zoom.

comment Why won't my Canon 60D take more than one photo with the internal flash, without closing it manually?
@BlueTile - Yes, that is exactly what those options are for. The assumption is that the flash may not be fully charged when a you want to take a shot, so use whatever charge is there anyway. Of course, the best if your flash is not working it to repair it or turn it off because when you use these options, the resulting exposure may be off as it is not clear whether your flash is not charging or it is just not sending the charge full signal. You may try dialing negative Flash Compensation (FC) just to see if it has an impact.

It really sounds defective and the problem is probably in the flash unit, the capacitor never registers fully charged, so the camera wait indefinitely. Check in the menu system is you have an option like Release Shutter while Charging or Shutter-Priority. It exists on some cameras but I don't have a 60D. If you have it, that should confirm the problem.

comment Increasing Lightroom performance when using spot removal brush
The amount of memory is certainly NOT your problem at the files sizes you mention. I work with large files in Lightroom within a VM running under Linux and I allocate each Windows 7 6-bit VM 8GB or RAM and two core without any issue until I reach huge panoramic images (100+ MP). The memory is dual-channel DDR3 though which is faster. Plus graphics is PCIe 2.0 x16. It used to be a Radeon HD4650 until last week but now I upgraded to an R7 250 and there is a noticeable speed-up on the redraw but not on the brush application.

comment Increasing Lightroom performance when using spot removal brush
@TekiusFanatikus - Sorry, didn't realize it was a laptop. Are you at least working on A/C power, many laptops run lower performance from the battery and even turn off discrete graphics? Unfortunately though, memory speed often makes MUCH more difference with laptop graphics since it is shared between the CPU and graphic chip, so there is more bandwidth being used.

comment What's the best method to change colours in a photo to another specific color?
Why restrict yourself to those two tools? It really makes solving your problem much more difficult. There are tools dedicated to replace colors.

comment Increasing Lightroom performance when using spot removal brush
What I suspect is that RAM is the limit. Disk is not involved once applying the healing brush. BUT you actually have enough RAM, 8GB can hold quite a few times that image, so I would look at what else you have running. Stop everything but Lightroom, including the Anti-Virus, which sometimes monitors DMA access. If it is still, slow, I would go for the fastest RAM your MB supports. This isn't an answer, just an educated guess :)
