I don't care if you say 40°C, 104°F or 313°K, it is too blinking hot for me in my old age (77 next month).
I think I will make a voodoo doll of the AC and perform a ritual to double its efficiency.
Two things. I've been in the UK many times. It's "unbearably hot" over 30°C if you don't have air conditioning, and air conditioning is rare in private homes. Second, are you ready for the rolling blackouts? They hit us with that two years ago. Temps in parts of the Central Valley are expected to hit 115°F on Monday and Tuesday. (112° in Sacramento).

I watch a video (Tony Northrop) who said, although you can use a full frame lens on a crop sensor camera, you will get better results using APC lenses with an APC camera. This is not what I have been hearing from other UHH members... You just get more reach.
Thanks for the clarification
This is generally correct, as he shows in the video. You can get better results for less money by using crop lenses on a crop body. The problem is that the selection of crop lenses is pathetic (to put it mildly). If you want fast lenses, you need to use full frame lenses.
And, there are a lot of focal lengths that just aren't covered by crop lenses. Especially telephoto lenses. Where crop bodies can excel if you still need to crop.
But the advice is still sound; if there is a quality crop lens that covers the focal lengths you want, you will get a comparitively better and less expensive result if you use the crop lens.
But if you really are interested in shooting a crop body and not a full frame body, then it is better to get a camera from a manufacturer that focuses on crop lenses as well.
The conclusion; except for a less expensive solution for wildlife, if you want a crop system, shoot a system designed for a crop sensor (Fuji, Olympus, Panasonic) and avoid the full frame (Nikon, Canon, Sony, Pentax).

Thanks, It's a 90mm macro and I've very fond of it -- great on an APS body.
Hmm?? Did he say what exactly he meant by "better results"? I presume he means comparing image quality. I tried that comparrison with many images soon after I bought my first full frame body. All I can figure is he must be a better pixel peeper than I am. Maybe he has an electron Microscope ? Truth be told, I'm just not a big fan of his for more than a few reasons. More opinions than proven facts far as I can tell.

I lived in Ceres and Modesto in 10th and 11th grades, then back to my hometown in Kentucky for 12th and my first two years of college. Then to southern California in Huntington park for several months before it was off to the Regular Army for 3 years, two in Vietnam. All places that can have "HOT" days. Then after the Army various places around the LA Area until I moved to Corona on the western edge of the Inland Empire were I still am. We are at 100° at 6PM after making 107°. The 10 day forecast is 100° to 107° for the next 7 days followed by a drop into the upper 80s.
Now the state regulators just announced a phase in of electric vehicles to reach 100% of new car sales by 2035 and two days later the state utility people told everyone to save electricity but some areas will still have "brownouts" and rolling blackouts. One of the things said on TV was "Don't charge your electric vehicle because is pulls 18X the electricity of the average refrigerator. They also announced that unless the feds help they will have to close a large atomic generator plant in a couple of years so we will have even less electricity.
W...T...F???

We are at 1800 feet. Peaking at 109 on Tuesday. Hotter down in the valley.

The thing I like about him is that he seems to try and test out how well a camera or lens performs rather than just saying a lens or whatever is better than this one for whatever reason. I find his critics usually dislike him for reasons other than his technical approach.
We are talking about camera brands that have full frame and crop. Fuji does not.

I don't get that from reading the OP's original post.

You were, but Panasonic does FF too.

"although you can use a full frame lens on a crop sensor camera, you will get better results using APC lenses with an APC camera." The context is using either a full frame lens or APC lens on APC camera.

Indeed! Thank you. I’m going to close the browser go shoot some pics.

From what I understand from reading here and elsewhere, a lens designed to cover a smaller area can perform better over that smaller area than a lens designed for a larger area. I read this as long ago as the 1970s where the resolution of 35mm, medium format and large format lenses were compared in something I read. The drop in resolution as the film size went up was compensated for by not needing to magnify the larger film sizes as much in either projection or printing.
Please post a link to the video so that we can see what you're seeing.

Junglejim, the bit about larger format needing less resolving power was true for large format, but I don't think it would enter into lenses for digital cameras. I have a crop-sensor Canon and I have some good EF-S (crop) lenses, but also a couple of EF (full frame) L zoom lenses. Their premium lenses (L series) do not come in EF-S. Although the L lenses have very little drop-off in quality toward the edges full frame, there is some--but the EF-S camera only uses the central part of the image--which is the best part.
