Yes. She was one of two would be battlecruisers (the other was the Saratoga) completed as aircraft carriers under the terms of the Washington Naval Treaty of 1921. They were CV-2 and CV-3 (our 2nd and 3rd fleet aircraft carriers) and were used throughout the 1920s and 1930s to develop doctrine for how carriers and their aircraft would be integrated with the fleet. She was happily not at Pearl Harbor during the attack and participated in several raids on Japanese held islands early in 1942. She was sunk by Japanese carrier aircraft during the Battle of the Coral Sea in May 1942–the first pure carrier vs carrier battle. It was a tactical defeat for the U.S. in that we lost the Lexington sunk and Yorktown damaged in exchange for a Japanese light carrier sunk and a fleet carrier damaged, but stopped a Japanese advance and helped set up Midway. Two hundred and sixteen of Lexinton’s crewmen were killed (I don’t think that includes men lost in her aircraft).

Apple has a list of supported cameras on line and update it as Photos gets tweaked for new cameras. When the D500 is added Photos will read the already loaded images. In the meantime, if you save RAW and JPEG, you will have a viewable version. I went through this when I got my 80D right after it went on sale and I think it took a month or six weeks to get on the list.

As a middle aged white guy, I’m surprised you still remembered them well enough to write such a excruciatingly boring analysis. And, this is from an old aged white guy.


It’s irritating to hear how political correctness makes humor impossible and then see a bunch of really lame put done jokes. Thinking about how they were set up was more interesting than just going into a rant, but still a waste of time.

The first is about a skewed approach to solving a problem, and most are about taking questions literally and/or ambiguous language. I kind of like the one about always buying $10 worth of gas since there’s an unintended point about economics. They would be as funny (or as unfunny) without specifying gender, ethnicity, etc. Try reading them and substituting middle aged white guy (my demographic group) for blond female. Or do you think middle aged white guys never make mistakes?

This is not going to be a "this format is better than...". It's simply going to clear up a few misconceptions bandied about on this forum regarding the jpg file format. In fact, it's only going to clear up one misconception about this file format. The jpg format is a lossy file format. This means it is going to lose data. An understanding of discrete cosine transforms would be helpful in understanding the process. However, suffice it to say, here's what this post is going to clear up.

If one opens a jpg file, looks at it, and closes it, nothing happens to the file.

If one opens a jpg file, looks at it, and saves it, it degrades.

This is just the nature of the jpg file format and the save algorithm. It's that simple. Open, Look, Close, nothing. Open, Look, Save, file changes.

Yes, one can edit a jpg. However, in addition to the edits one makes, the save process works just the same making additional changes to the file over which the photographer has no control. The only control the photographer has is how much more gets changed based on the amount of compression selected at the time of saving the file.

If you don't believe this, it's simple to prove. Using the diff function in UNIX, or the free Windows program windiff will show you the changes. Can you visually see them, perhaps yes, perhaps no. The changes are there none the less. Again, it requires nothing more than a Save to instigate a change to the file.

Am I correct in concluding that the size of the file, say 2 MB for a jpg from my G16, would go down over time? If so, what is the rate of loss per Save? Or does this vary depending on the software being used?

Having decided to buy one of these cameras, Lumix GX85 and Canon SL2, I have some questions:

1. Does Nikon makes a camera with similar specs and price and which is that so I can add it to the list?
2. Can any of you rate these cameras plus his proposed Nikon? Elaborate as mush as possible. Image quality is the main consideration. On the other hand high price is a deterrent. Compact too. Try to stay under $1000 or even $800 including tax.
3. Do you strongly suggest any other brand, but do not try to prove without reason that what you have is the best. Be objective if you can.

I know these are common questions but when you are stuck you need some good help.

Thank you

I have a Canon 80D plus several Canon point and shoots and an Olympus M10 MkII. I recently rented a GX85 and an SL2 plus a Canon M5 and M6 to make comparisons and help my wife transition from her iPhone to a digital camera.

If you haven’t handled the GX85 and SL2, I would urge you to do so, along with anything else in your final three. Specs are obviously important, but you have to be comfortable with the camera and lenses. I would suggest also playing around with the different menus to try to see if one seems more intuitive to you.

Of the two cameras, the GX85 is clearly the more advanced and it has a good range of available lenses. For me a big downside would be the ergonomics—I found the SL2 much easier to handle. I like that the SL2 has the same 24MP sensor as the 80D with newer processing software, and I generally prefer an optical view finder, although the one on the SL2 isn’t the best. The big drawbacks on the SL2 would be the 9 point-autofocus, which is pretty skimpy by today’s standards, and the absence of built-in stabliztion and 4K video. It’s also a little bulkier.

Since the specifications seem to heavily favor the GX85, it would be helpful to know why both of them made your short list. What do you like or dislike about each of them?

[quote=thephotoman]You must be skinny. For one thing, it is very difficult at older ages to loose weight. Secondly, one could have physical problems that might make it hard to tote a lot of weight.
If you are young, skinny and without ailments, it would be hard to understand those who have 1 or more of these conditions. Just for the record, I am 67, have asthma and bad legs on many days. I lost 50# so far and I am down to my weight when I was carrying my 40# backpack without out a problem. Now I can not carry it very far. I do hope the loss of another 50# will help. It may help, but my other conditions may still make it hard to do.[/quoteT

Thanks for the dose of reality, and good luck with your effort to lose more weight.

Just musing this morning. All the discussion of the light weight purpose of mirrorless systems and how many large lenses defeats this goal got me thinking. How laughable some of this is when the opinion is being expressed by someone who is 50 to 100 pounds overweight. Certainly an effort to shed a few pounds could negate the small difference between a DSLR and a Mirrorless equivalent? Happy Holidays may you and your kit cumulative weight lose a few pounds this new year.


This is silly. I am 6 ft. tall and weigh 180 lbs. My 80D weighs around 40 oz. with a typical lens attached, about 1.4% of my body weight. My M10 MkII with a small lens weighs about half of that. There is a significant weight difference between the two cameras—one weighs twice as much as the other—but at around 7/10 of one percent it’s trivial compared to my body weight. I notice the difference between the two cameras because of the difference in stress on my arms and neck or shoulder, not because I have increased or decreased my total body weight by less than one percent.

Ed ... 42MP is not a priority ... that's just what the a99II comes with. I believe it's the same sensor Sony put in one of their mirror-less models.

It's 6MP less than the new Nikon D850, 8MP less than the Canon 5D S / R ... and 6MP MORE than the well-considered Pentax K-1. But, at least - that one is a grand or more cheaper.

It's not the Res that's a priority ... although, if you're spending over three grand for a camera - it DOES make sense to figure Max Res into the equation. Weight is the absolute priority ... and - related to that - size or bulk. The a99 II is the same body as the a77 and a77 II - both of which I have, and know, therefore - I can handle. I'm just trying to figure out if there's anything lighter and/or cheaper ... another large consideration.
Ed ... 42MP is not a priority ... that's just what... (show quote)


Okay, if you truly want something cheaper and lighter than the a99 II but 42 MP isn’t necessary, then what about the a99 II is necessary? And since lighter than 29.95 oz. covers a lot of territory, what weight are you looking for? It looks like the lower limit of what’s available in Full- Frame DSLRs is about 22 oz.

Said nothing about Mirror-less, much less FF compacts ...

A DSLR has interchangeable lenses, and uses a reflex mirror and prism to reflect the images to your eye ... I LIKE that!!!!

It's not a guessing game, ED ... I am truly looking for a cheaper alternative to the Sony alpha a99 II - which is 42MP, and $3200 ...

However, it uses the same body as both my APS-C alphas - the a77 and the a77II ... so, if this fails to turn up something - that's my new dig cam!

“The criteria specified a ‘LIGHT Full-Frame DSLR’.... It’ not a guessing game...I am truly looking for a cheaper alternative to the Sony Alpha a99 II - which is 42 MP, and $3200...”

Okay, you want a 42 MP DSLR that costs less than $3200 and presumably weighs less than 29.95 oz. I’ll leave it to others to track that down.

Thanks, Ed ...except for the 6D and the Leica ... all the rest are mirror-less ... and the RX1R is a fixed-lens compact ....

Not too keen on mirror-less ... I like using OVFs ... the EVFs in my SLTs - were enough of a change for me ...

At least - they are all still - basically - DSLRs - at heart ....


Like I said, your criteria are entirely subjective, which is fine, but that makes it highly unlikely that someone will guess the answer you’re looking for.

We all know the shortcuts to lightweight digital photography, don't we? ... One answer is APS-C (crop-sensor cameras) ... a step in the right direction - but when you add a long tele-zoom on it ... you're right back there with weight issues. Some go the bridge route - which is fine, but you do sacrifice a level of performance. Others swear by the MFT solution, which gives you about half the sensor size of a full-frame dig cam. It's acceptable for many. But, this post will attempt to get to the bottom of the solution, from the top - if you will. If you have suggestions for a really LIGHT full-frame DSLR - I'd love to hear them. And, no - they don't have to be from one of the major four, either. Any other maker's full frame DSLRs - will be considered ...

If you want a “really LIGHT” full frame camera, then the answer is entirely subjective.

If you want the lightest available full-frame DSLR, then it’s a matter of looking at the specs—nothing else to be considered. I believe the original Sony A7 is the lightest, but here’s a list of models in the 16 to 24 oz. range. Sony A7 weighs 16.7 oz., Sony A7 II weighs 19.6 oz., Sony A7R II weighs 22.1 oz., Sony A9 weighs 23.7, Leica M-P weighs 24 oz, Canon 6D weighs 24.2 oz. You might also consider the Sony RX1R II at 17.9 oz. and the Leica Q at 22.6
