I am not quite sure what feature is not working. I have the Canon RF 24-240 and use it extensively on both my Canon R and R5 with no problems.

TechSpot. Office 2021 Lifetime license no subscription. I got it, I use it, works fine. Be careful when you order to select Mac or Windows as appropriate.

Canon R7 with RFs lenses would be attractive. IBIS good focus APSC with 30mp. If the M series would suffice M50MkII somewhat limited M series lens selection but enough for almost any situation - and with and adapter she can use all her EF lenses.

Marie Curie Sklodowska - a great woman at a time when it was rare for women to do that level of study and research. I am proud that she is a somewhat distant relative.

I have the EF 85mm f/1.2L. It is a fine lens and works great on my R5 with an adapter. It is also a bit heavy so I did get the RF 85mm f/2 for convenience in walking around - it is also a fine lens.

Canon. You can get the info on their web site. They did a good job on my EF 28 - 300L after it got dropped.

Cute. Cheers.

Most of my flying any more is local for viewing the scenery, coast etc. That and visits to family. Usually it is just my wife and myself. I was night current recently and probably will do it again if I feel the need. I try to practice at one of the shorter narrower runway airports near by. The time will come for me, as it does for all of us, to hang up the headset but I think I still have a bit of time left. The increase in restricted and controlled areas is a pain and I try to avoid them as much as possible but the airport near my son's house is in a class C so I put up with it there.

All true - but at 85 I am still at it! My last trip from central CA to Northern AL I think I beat the airlines - too many lines check ins and layovers. Fuel cost about balences out for 2 people not so much for 1 but really good for 3.

I won't go commercial anywhere in North America. Just fly myself - no TSA, no waiting lines, no schedule issues.

Temperature certainly affects both Lithium ion and lead acid batteries. I don't have good numbers but I have heard that, in the extreme, the capacity could go down to 60%. On my Tesla you can program it to charge and pre-condition the battery for a specified departure time. That would reduce the environmental thermal effects since the energy to warm up the battery would come from the charging circuit. Our temperatures often go to the low 30s at night and occasionally into the teens. I don't see a major capacity reduction. Consumer Report did some testing and indicates the 50 - 60F range is probably the worst.

Well they have examples that have gone the equivalent of 2 million miles.
More realistically, my sister has an older model S (2015) whose battery needed replacement after over 150,000 mi. It is a function of not just charging but how you charge and how much fast charging you do. The good news was Tesla replaced her battery at no charge under their standard guarantee. I think Tesla guarantees no more than 15% reduction in capacity in 250,000 mi or 10 years - I would have to check the actual paperwork to get the exact numbers.

I have been driving an electric vehicle since the begining of 2019. Like any other vehicle you have to be aware of fuel/energy requirements. Liquid fueled autos use more energy in very cold and hot weather as do electric vehicles.
I charge over 90% of the time at home - we only charge at charging stations on longer trips. We live on California's central coast and can make it to or from Yosemite NP or down to San Diego or San Francisco on one full charge.
Cost wise, using current power costs we save around $70 to $100 /mo based on Power Co Charging. In reality we have Solar so the cost saving is quite a bit more. On the road charging is what the charge at the charging station is and that is typically quite a bit less than what we would have spent on gasoline or diesel. In addition the service cost is much lower with an EV no oil changes etc. Some fluid changes every 2 years or so.
So it is, as in all things, how you use your vehicle that affects the affordability decision. If your driving is mostly around town or commutes up to 60 or 100mi. each way or so - the EV will save you big time. For long trips it will still save you money but you need to be more aware of where you charge - generally not a problem in most area.
I hope this helps.

Great set. I have seen this before but it was a long long time ago - I am in my 80s.

With the RF system you can use both. I do all the time. Canon,indeed, recommends using both for increased stability.
