I would not use a monopod as a trekking pole unless it is rated for over 75 pounds. If you are hiking up steep trails you can put a considerable amount of weight on the pole and you do not want it to fail on you.

Keep at it. Canon does not even make batteries for their cameras, the vast majority of them are made for Canon by Panasonic.
Never said they make their own batteries, but they do set the specifications for them I imagine and they call them Canon batteries like I did.

Your point is well taken. I am not familiar with these pro level cameras and a Google search only shows the 7.2-7.4 V batteries. As I stated previously there may be cameras I am not familiar with. I understand the basic cells and they all produce the same voltage and all lithium batteries are a multiple of that voltage. As far as the discussion of 3rd party batteries and chargers go my opinion remains the same. Not sure if you are disputing that.

Not really. As far as Canon and all DSLR batteries go I forgot that they had two cells in series. My bad. The main point is correct: 3rd party batteries all have the same voltage and require the same charging voltage. In principle, without a special security chip, any 3rd parties charger should work on any of these batteries. This is true for Canon, Nikon, Sony etc. Of course the configuration and dimensions of the battery will mean many different shapes for the chargers. There are small details of construction in the cells that make Canon batteries slightly better than 3rd party in terms of total number of shots you get. If you think that that small difference is worth the premium price then go for it.

A correction here. All Canon batteries are actually two cells in series for 7.2 Volts.

Absolutely not. My Lithium batteries are 3.7v, 7.2v, 11.1v, 14.2v, 18v, and 24v. Where do you come up with this ridiculous idea???
I have this idea because I am a Ph.D. chemist. You are referring to general lithium cell batteries that may power a variety of devices. They consist of a number of cells connected in series. Camera batteries consist of a single cell lithium, which have a nominal voltage between 3.6 and 3.7. At least for common cameras. There may be some I am not aware of with specialized applications, i.e. high speed cameras, that require higher voltages. But we are talking about batteries for DSLR's here so I stand by my statement. Maybe not so ridiculous after all??

That is because you have batteries connected in series. Single cell lithium batteries all have the same voltage since they use the same chemistry.

I have used 3rd party batteries for all my Canon cameras: 40D, 60D, 5d Mark II, and 5DS. Had good luck with all of them. Some were bundled with their own charger but the Canon one worked for all. Yes, they do not last as long; maybe 75-80% of the Canon battery at 1/5 the price. So I carry an extra battery and seldom need to use it unless on a special vacation trip. Note: that 3rd party charger will also charge your Canon battery. All lithium batteries have the same voltage and the same charging requirements.

I always shot both as it gives me more flexibility. Like using a dual band router on the internet. Why limit yourself so you can proclaim that you only shoot RAW.
Because you are not limited if you find you never, ever use the JPEG's and they do take up space on your memory card.

When shooting portraits with an 85mm lens what f stop do you like to use? I'm looking for nice bokeh but also with sharpness on subjects. Here is a shot of my wife and new granddaughter. I would have liked my granddaughter to be sharper... This was shot at f1.8 and I think 2.8 might have done better but at the expense of a nicer background.
Is there a good rule of thumb?
Should I consider focus stacking and if so, whats a good method?

Difficult to do focus stacking on subjects that move as the alignment of them will be off.

Looks like spot metering to me. The second shot would meter the black shirt overexposing everything else.

RAW only. It beats JPEGS in image quality in every way. If you need a JPEG quickly shoot it with your phone and post. I'm retired so I don't need to do anything quickly, nor am I capable of doing anything quickly.

This is very helpful. Thanks a lot. Note, I will not be using this for very much post processing as I do that on my desktop. As it is really just for travel, and I do that a lot, I wanted something light and portable so I will probably go with a smaller screen size but will take your recommendations to heart.

My old laptop, that I only use for travel, worked fine with Photoshop CC and Canon 7D Mark II but has slowed to a snail's pace with my new Canon 5DS. Any recommendations/experience with a reasonably priced laptop that could handle these larger files? I assume I will need at least 8 GB of RAM but don't know much about the core processors available. Screen quality is less of a concern as I use it only to transfer files to an external drive and for preliminary examination of the day's shots.
