According to Phillip Bloom, some EF-S lenses will work if one removes the rear protective ring. "Using with EF-S lenses. The EF-S mount has the same 44mm flange distance as the EF-mount, but the rear of the lens is allowed to protrude a few mm further into the mount aperture and possibly hitting the optics of the Speed Booster. You may be able to mount some EF-S lenses by removing the protective ring protruding from the rear of the EF-S lens."

I would...and will....
especially considering that I dislike the 18-200 kit lens as being too soft. Canon glass, if will work with the speedbooster at f/2.5.

No, no revision to the lens, however, metabones is saying something about an adapter that works with APS-C lenses. If nothing else, I can use it on my B-cam, a Canon 7D.

Waiting for this lens to arrive. Been checking the MTF's at Canon, USA. This lens looks to have equal or better contrast and resolution than the Canon 24-105, or 28-135. DPreview shows some CA, but, hell, I think that's deriguer for a cheap lens, like this. I looked at the reviews for the Tamron and Sigma. The Sigma is the worst performer of the bunch. Tamron has less CA but lower resolution, but, the big selling point for the Tamron is the warantee. Since modifying the lens will void the warantee, this is a non-issue for me.

Got this Canon 18-200 lens in da mail, today. Here's my initial impressions: -It's up to the standards one might expect from Canon. VERY well made, feels solid, not plastic. -This lens will NOT fit on the Metabones Speedbooster; however, it does fit, quite nicely, on the Metabones standard EOS to E-Mount adapter and f/stop works . -The lens appears to maintain focus thruout the zoom range. HAving said that, the image looks a wee bit soft at the wide angle. Here's a couple of screengrabs. These were shot via an O7Q, recording 4K2HD using the REC709 profile. Screengrabs come from imports into Davinci Resolve. edit: these images don't do the real images well. If you would like the original jpegs, drop me a line.

I see no benefits really unless it's super sharp etc over the Sony 18-200 power zoom. With the Sony you have great auto focus, face recognition, stabilisation, power zoom and it's just a wee bit slower at 6.3 at the tele end.
and it's not the mount really that's the problem with aps-c lenses and speedboosters. They will vignette heavily cause they're not made to cover a full frame.

I've never liked that sony kit lens. sure, it makes things easier with auto everything, but, it's too soft for my liking, especially at 4k. I'm x-checking this on my 7D, but, initial images look much sharper than the REC709 from the FS700. Next is to do some 4k RAW on the FS700 to see if it looks better. I don't do much run and gun, so this lens seems pretty nice for stage shots. Not seeing any vignetting, but, there is mild pincushion at the widest setting.

If you want a superzoom that works on the speedbooster, try the Tamron 28-300 f3.5-6.3. On the speedbooster it is a 20-215mm f2.5-4.5, which isn't a bad stop for a superzoom, and these days the lens costs ~$400 new, less used. I've been using it for a while and am quite happy with it. As with most superzooms, it breathes a lot on the long end, and the VR (IS) is very aggressive which can be good but also it has trouble transitioning to movement so it will lock on and to a stable shot but then jumps when you have any movement outside of the threshold of what it can stabilize which looks a bit jarring. Also it can flare fairly easily and focuses backwards, but at least it doesn't ghost, and generally I've been surprised how well it performs for 1080p. Canon also has a 28-300 f3.5-5.6, which I haven't tried but it is a $2500 lens and is 3x the size and weight of the tamron. Tamron is supposed to come out with a new version of their full frame superzoom soon, but I'm not sure exactly when. Those are literally the only options for full frame superzooms in the market as far as I know.
Here's a student film I shot while working at a film school and shot entirely on the FS700, speedbooster, and that Tamron 28-300 lens.

Thanx, Noah, I'll have a go at this Tamron. It looks good. BTW, after some testing with 4k RAW, I'm really liking this lens. It doesn't look that sharp with 4K2HD/REC709, but, with RAW, this lens is tack sharp....and it looks rather filmic...I'm liking it. Getting more experince with this Canon superzoom. Shooting at f/8 in 4k, the images are astonishing. I'm liking this lens a whole lot.

Sounds good. Let us know how you like it when it arrives. Also do you know if it "focuses backwards" ? This is what nyvz wrote about the Tamron 28-300 f3.5-6.3 - so might be the same with the 16-300mm?

+1 - the Canon sounds nice, but not nice enough for me to bother swapping it out for the Sony kit lens - the extra length (at no cost to stop) however, certainly is worth looking at on the Tamron - as long as it is as sharp as the Sony (which shouldn't be that hard) and doesn't have any excessive distortion characteristics.

Cuervo, I would be interested in a comparison test of your new lens with the kit lens, if you got a chance.

Hi Jim, I have a gig next week for a new indie with Hector Echevarria. After I get this outa da way, I'll work on a comparison. I plan on using the kit lens for hand held, but, I'll use the Canon for the tripod work. Just offhand, from what I've seen so far, the Canon beats the Sony hands down, wide open. Down around f/8, things get to be more of a horse race. People love to praise a lens for it's bokeh, but, not it's resolution stopped down at the sweet spot. I really dislike the finite f/stops of a canon still camera lens, just because it causes sudden changes in exposure. But, I've changed my technique to allow the gain to autoadjust up to 1 f/stop. This really smooths out those exposure changes and keeps that lens at a fixed f/stop and DOF. -Bill

So you just use the gain mode in auto with it limited to +6dB? I've never used auto gain - just tried it and it looks ok. Do you have any problems or limitations or is it super smooth?
Edit- just playing and it is quite smooth.

Paul, As you've discovered, it's quite smooth. Not discernable, AFAIK, unless you change lighting real fast, in my case, zoom too fast ( changing f/number with focal length).
