ZeroOne01: So, all that “beauty” is gone boooof.

Why just digital alterations? Shouldn't cosmetic surgery be included as well... :)

Horshack: Adding eye input AF creates an interesting dilemma when using face/eye tracking AF - focus on the eye or with it? 😀

Intuitive use would seem to be:
1. Look at where you want the focus to be
2. Press button to lock the target
3. Let the camera follow the target
Interesting to see if that is even close. :)

SomeGuyWithACamera: Why did Canon choose such huge focal lengths for macro lenses? DOF is always the limiting factor with macro and these high focal lengths are not going to help that. I'm sure it will be WONDERFULY sharp glass, and 8 stops of stabilization sounds heavenly but odd length choices to my experience.

About 150 and 180: Too short with full frame. :)

Kevin DiOssi: I’m personally not sure why anyone is buying Yongnuo products anymore with a company like Godox/Flashpoint creating vastly superior products in a full ecosystem at the same cost. You can buy an Flashpoint/Godox equal to this flash with built-int R2 triggers for the same price that will communicate with 100, 200, 300, 400, and 600ws strobes.

And with 3 flashes I'd need 2 powerbacks, which more than doubles the price. No thanks. As to the 600Ws strobe ... I already need ND filter most of the time even though I operate around 1/64 power. Godox might be better, but apparently not for me.

Power settings - Check. Price - Check. How about the mains power? In Yongnuo the PC socket was easy to replace with AC female socket.

Do tell which Godox is priced similar to YN560-series, offers remote control down to 1/128 with 1/3 steps and is easily modified to mains power?

Ilia Snopchenko: Any differences between this and the previous version except the finish? Even the deplorable focus clutch is still there. :)

Silent Drive module seems to be the point here.

TN Args: My key takeaway is that manufacturers must be well and truly sick of lenses being returned that are merely variations. And they know perfectly well that the customers do not know enough and believe they know more than they actually do know, so it is futile and really against their interests to battle with them or try to educate them. Such customers simply won’t believe that the manufacturer is telling the truth, and think that they are giving excuses of convenience. Sadly, it’s a lose-lose situation, unless these lens-returning zealots start to learn what they are doing wrong.

On the other hand, they might eventually get the notion that their specification just does not suffice for the intended market.

mike earussi: So what you're saying is that manufacturing tolerances will ultimately limit the absolute resolution of any camera system. So we'll eventually get to the point where an increase in sensor mp count will be useless.

You forget advertising. Think about scanner resolutions for a moment. :)

Those stands seem rather interesting for personal monitor, but flat 38" screen is a bit of a reach for that purpose. The 32" is largish too, but works ... barely.

Mister Anders0n: Also, this lens appears to be fixed focus? I see in the video review on their site that the focus ring actually just controls magnification (1:1, 2:1, etc). So once it's set to your goal, say 5:1, you can't actually adjust focus? Looks like you need to physically move the camera or subject?

If you don't need the magnification ... the entire discussion is moot. You don't buy this for 1:1.

If you do need it, the choices are this, MP-E, 2.5-5x (or whatever the range was) or various combinations of bellows, reversed lenses, stacked lenses and microscope objectives. The first three are relatively easy to use. :)

If this doesn't beat MP-E in image quality, I'm not interested. That one has room for improvement above 2.5 or so.

Both lenses work the same way except that Canon's MP-E65 does have automatic aperture.

Stacking with either of these will require rail - either manual or computer controlled. The optimal step size at 5:1 is somewhere around 30 um, so cheap rails won't really do.

On second thought - telecentric lenses might behave differently.

And did you check whether the magnification changed at the same time?

That is not different from any other lens except that in a non-macro the effect is not noticeable.

JoeOe: Honest question: How do I, in real life, get a life and moving insect in focus at x5 macro? I struggle at 1:1 with my bees and flowers.

Are the insect pictures focus stacked, or flash and very small aperture?

Focus is easy. Finding it in the first place is the difficult part. :) Usually I locate it in 1:1 and then increase mag while keeping the target in sight.

Kashim: The specs on this lens look very interesting, but I'm not familiar with this ZY Optics company or the quality of their products.

Also, it says the lens is fully manual. I assume that includes aperture control? Good luck trying to see anything beyond 1x magnification and F8 or lower (have to use small aperture to get decent DoF). I shoot only live insects and spiders using 1-1.5x magnification and aperture range of F11-F13, so would this lens be of any use to me? I've tried a couple of manual lenses before (meaning no auto focus), but never one where the camera couldn't control the aperture.

Sure you do. EVF (or screen) just compensates for it. The end result is you'll get more noise in the EVF.

Kjeld Olesen: Not wanting to be negative here, but judging from the image of the mount, there seem to be no electronic aperture. Focusing wide open and then having to turn the aperture ring before taking the image could be somewhat problematic at 5x magnification. I will stick to my Canon EF 65 mm :-)

Not a problem for stacking - you'd want to use it pretty much wide open IF the picture quality is good. And if it is not, there is no point. At 5:1 it really should be f/2.

Funny thing - latest e-mail from Canon <mail@comms.canon-europe.com> claims that full trinity has been released. Apparently someone didn't remember to update the picture after the release of 70-200 was postponed (I assume).
