Experience the best that both sides of the analog world have to offer with the improved 1968 Mk II from Drawmer, a two-channel hybrid FET/tube compressor with dual mono or stereo operation. The 1968 Mk II sports an ultrafast JFET circuit for the compression section, and a warm 12AX7 tube circuit for the amplifier, delivering up to +20 dB of makeup gain.

This 1 RU, soft-knee compressor features six switched attack times (2, 9, 15, 25, 30, and 50 ms) and three fixed release times (100 ms, 500 ms, and 1 second) as well as three automatic, program-dependent release times: 200 ms to 2 sec, 500 ms to 5 sec, and 1 to 10 seconds. Full stereo sidechain facilities are provided via 1/4" inserts, and the 1968 Mk II also brings a few extra tricks to the table as well, including Big and Bigger modes which activate 75 and 150 Hz filters respectively to lessen low-frequency processing and enhance low-end response as well as numerous internal jumpers for customizing performance features, such as removing the soft clip section, or increasing the output level by 6 dB when needed. This compressor includes an AC power cord and an internal voltage switch for global compatibility.

Featured on both channels is a switchable Big and Bigger mode, which applies less processing to the fundamental low frequency but still disciplines the upward associated harmonics. If these frequencies are untamed, they can result in an undesirable boomy or boxy sound.

The result is a solid bottom end with enhanced sub-bass and a smoother, wider frequency response overall. This lets the operator use more compression on an overall mix with less pumping action caused by a kick or bass instrument.

The 1968 MkII provides full sidechain access for connecting an external equalizer for vocal stressing, de-essing, or frequency-dependent compression. You can also connect external instruments and track segments for creating the bass-heavy pumping effects desired in dance music and other musical styles. Each channel has its own sidechain insert, so you can engage in either dual-mono or full stereo sidechain compression.

The outputs of Channels 1 and 2 are monitored on two yellow illuminated VU meters, with a red warning glow to signify approaching clipping. A three-position switch adjusts the meters to show either normal output level, gain reduction, or +10 dB VU mode, which re-scales the meter for users working at extra hot output levels. An output switch selects normal compressor output, hard-wired bypass, or sidechain listen.

Q: 1. Is this compatible with my EOS 5D Mark II? Can I get a 1:1 ratio using my (non-macro) 50mm Canon?lens?

A: Yes. The 5D is a full frame camera, so you will get the full 1x field of view with that camera

Q: 2. extender ef1.4 and ef2x connect f24-105 4 is usm to 5d markiii will it work?

A: yes, it works.

Q: 3. Will this work on a Sachtler FSB 8 MK II on a Dana Dolly or Matthews Dutti Dolly?

A: The Sachtler Adapter 75/100 FSB Mk II would allow you to mount the Sachtler FSB 8 MK II on the 100mm bowl adapters of the Dana Dolly or Matthews Dutti Dolly, however using the 75mm bowl adapters included with those dollies along with the included tiedown would result in a more secure setup.

Q: 4. this Canon Extension Tube EF 12 work for my sony 6500 to Canon EF-S 10-18mm f/4.5-5.6 IS STM Lens?

A: I doubt it as the lens mounts are different.

Q: 5. can I use it on 200mm 2.8L II to shorten the distance between me and my subject while doing portrait photography?

A: It's got minimum distance and maximum distance which is very limited and beyond which everything is blurry . This extender tube it's only for macro photography and nothing else !

Q: 6. What kind of results can one expect using Canon's 70-300L? How much closer is focusing improved?

A: Basically you will use this so your Canon EF 70-300mm f/4-5.6L IS USM Lens will be able to focus closer than the lens's native close focusing distance of 3.94' / 1.2 m. We were not able to find information as to how much closer but we would guess that bout 2' would not be unreasonable. People with telephoto lenses by this to do exactly this, get a closer focusing distance. This can be an excellent too.

Q: 7. I have a Canon EOS Rebel T6 with a 18-55mm lens, will the extension tube EF 12II work with it?

A: Yes It will work. As David A. mentions just pay attention to your focus.

Q: 8. Anyone used this with a Canon 50mm F/1.2 L (I'm using a 5D mk iii but assume anyone w/ a 1.2L is using a pro body). Results? Presume it preserves the amazing qualities of the 1.2?

A: With the extension tube, the quality of the lens is preserved quite well.

Q: 9. Where is this Canon extension tube manufactured?

A: Country of origin is Japan.

Q: 10. is this extension work with my canon 60d and lens 18-200 ?

A: The Canon Extension Tube EF 12 II is compatible with both the Canon 60D and the EF-S 18-200mm lens.
