Bob,
Not an attempt to convince anyone either way, but I see a lot of guys selling off their other gear to buy mirrorless without knowing the negatives, and I'm glad I didn't do that without getting my feet wet first.

I looked at switching from my Nikon D800 to a Sony A7III when considering moving up to the D850. I did the same analysis and concluded that with like ( f2.8) lenses the Sony was in some cases heavier. In addition you had to navigate a complex menu system to make key adjustments where the nikon had a button. The final blow was the cost of acquiring a whole new system. It didn't improve weight, functionality and cost thousands. I bought the 850 and sold my 800 for $2,500 net.

A 3-second start up time doesn't seem all that bad; that's about how long it takes to activate my pocket camera. One simply needs to get into the habit of switching on the camera before the viewfinder has reached one's eye, such that it is ready by the time it is in position. With a little practice this maneuver can be executed automatically and effectively. And then of course leaving the camera turned on until it is no longer needed and ready to be put away.



Has anybody compared the start up time of the sony a 6000 with the Olympics?

I don't get the mirrorless EVF lag time issue that the DSLR folk raise all the time...

EVF lag is speed-of-light, and worst case is of the order of a frame video refresh time (30ms).

By contrast, the mechanical time for the mirror to flip up has to be at least in the same magnitude. A 9fps burst rate for the d850 implies that the mirror goes up or down 18 x per second, or once every 55ms; allowing time for the exposure (lets pick 10mS), the mirror could take 40mS to flip out of the way.
If the mirror accelerates from rest to speed to rest to move 2cm out of the way in 40ms, it must accelerate at .02m / (.04/2)^2 = 50g, a not inconsiderable feat. (This is simplified, since it ignores the angular or rotational component of motion.)

Also, DSLR focusing has to be locked before the mirror starts to move, with a delay until the image is taken. Mirrorless focusing can continue to track right up until the exposure starts -- or equivalently, exposure can start as soon as the focus has locked, no additional delay for mirror flip up.

I don’t own the 40-150...but I don’t see the draw to this lens. It’s fairly big and heavy for what is is. I’d rather carry/shoot my 75mm f1.8 along side of the 12-40. That combo (em1, 12-40 and 75) fits nicely in a tamarac velocity 6 sling.


And a small EPL for that second lens means no changing with not much increase in storage; I have a little Lowepro fanny/side pack that holds 2 EPLs and lenses just fine; a nice " Lite "kit.

You can look up the numbers on dpreview, but what do you guys shoot that it is an important part of your decisions? Does a few milliseconds either way really count?

yah, that feature is VERY compelling. Colder the bug, the better, in that case. The Oly focus stacking would make a great post subject. I would bet a lot of us are curious about real world experience on that.


With or without tripod? Either way, if you search, google should provide plenty of evidence. I’ll try to post a link tonight for you. Unless you want to see my personal results.

The Oly has approx. 1 stop less image quality concerning ISO. The sensor has approx. 1 stop more equivalent DOF. To make the two systems more equivalent, the lens F-stop should account for that.


At what ISO?

I will stick with my Pentax with IBIS and optical viewfinder I actually despise small light cameras which is all personal preference and that is why they make many different cameras and brands.

I'm not unhappy with the camera, per se. I use it pretty much as I envisioned. I carry both the Oly w/ the 12-40 as my wide lens camera, and the 80d w/70-200 as the tele component, switching as needed, works perfectly. I'm more concerned about cautioning guys who are selling their gear to go mirrorless before THEY properly research it.

And I, a 4/3rds user, agree. There are pros and cons for every camera and every format. One should not be enthralled by the the accolades of satisfied camera owners for a camera that met their wants and needs - because those might not be your wants and needs. You are right to tell everyone "Beware : do your research". My 4/3rds will not meet everyone's needs.

For me, one major requirement was weatherproof. When I am traveling, I must get shots rain or shine. I must be able to show people that if they spend their hard earned money to go somewhere, they can still see and do things that are fun no matter what weather they encounter. The sun doesn't always shine in paradise (or elsewhere). I do not know or even see a lot of photographers out in the rain, soaked down to their underwear and socks, like I sometimes am to get shots.

Now some of the newer FFs and APS-Cs are finally being weatherproofed, but not back when I started my system. And a rain cover and tripod were too cumbersome for my needs back then. Is weatherproof that big a deal for a lot of photographers? No, not for most of the photographers I see. Then why would one pay for the expense of weatherproof? Or anything else they don't need. In Olympus terms that is $650 versus $1100 and $2000. All other brands are similar no matter what the brand.

It always comes down to properly researching one's wants and needs. That is the only way one will come close to being as satisfied as all those accolades indicate.

It is important to research the product one is about to invest in. Sounds like you didn’t really do your home work. If I were to read about the D500 and it’s amazing CAF/tracking but I purchase a d5600 and not being happy with the results, is that the fault of DSLRs or mine?

The em5 mark2 is a mid tear camera. If you want the best m4/3 has to offer, (very fast startup time for example) play around with an EM1/gh5/g9.


Amen. The top tier cameras are, well, top tier. They’re expensive, but you get what you pay for. The OP bought great (although unusually heavy) Olympus lenses, but a middling body.

I’m a former Canon and Nikon user, very happy I made the switch to Panasonic. But then, my GH4 meets my needs very precisely.

There is no substitute for careful research, and for renting or borrowing to try before you buy.

And there is even more to think about when you buy a pro level camera. It will have pro level bells and whistles to learn - lots of them! I thought my step up from the E-M5 (not a mrII) to the E-M1 mrII would be a moderate step up, I thought it wasn't going to be that much more to learn. And, to a certain degree, I was right. The items that I upgraded for were there for the learning. But I also found out there is a lot more customizing to be learned that has not been talked about much.

That is a common complaint about Olympus and Sony menus. With Panasonic and Fujifilm gear, not so much.

It has not been all that bad. It's more like you ordered that normal looking cheeseburger and with the first bite you found it to be a lot bigger and better tasting that you thought it was going to be.

Let's see... There's a mix of three different formats there, so you can't be referring to sensor size...

I'm not referring to output or MP or pixel pitch or anything.

Menus and ergonomics do differ wildly from brand to brand and quite a bit within each brand. Most folks go with what they are the most used to, like Macs vs PCs, Fords vs Chevys, or Lexus vs BMW... Hence, the admonition to try before you buy. The tools that seem absolutely intuitive to one person can seem completely confusing to another. What feels good in the hand varies with hand shape, size, muscle tone, and more.
