L Mount Speedbooster

Any CL owners keen to have a focal reducer/speed booster adapter for the CL?

 

I know they can't do an M to TL mount speed booster but an R to TL speed booster would be awesome! And of course other vintage SLR mounts like MD.

 

I've used MD lenses on my M10 and they work great. Also used a focal reducer to fit my MD lenses onto my MFT system - the MD 50/1.4 becomes a 71mm f1 and the 24/2 becomes a 34mm f1.4.

 

I believe the conversion for the CL would be basically the same.

I don’t think there’s any focal reducer for cl, I have 2 focal reducer for fuji Mount and one for e mount, wondering if i can modify them into L mount. I think It’s totally possible, Too bad I don’t have the skill or tools required for that.

Dear all,

Given the new slew of full frame L mount lenses entering the market, I was wondering if anyone had heard of any rumours of an L mount Speedbooster / focal reducer? Would be useful for the TL / CL line, especially when considering there is a distinct lack of fast APSC telephoto lenses currently available for portraits...

Just pick a fast focal length in L mount FF lenses that's shorter for portrait work. A 50mm f/1.4 is a fantastic portrait lens for APS-C, so is a 75 or 90.

Or a Summilux 50-M

Or a Summilux-R 50mm f/1.4:

Would love an L mount speedbooster. Would make me go for an 85mm 1.2 in a heartbeat...

Oh yes, please to speedbooster for R lenses. Maybe with L-mount alliance and Sigma saying they would make APS-C foveon mirrorless, will make such move financially feasible.

The APSC sensor has really caught up with full frame in regards to detail, dynamic range and noise control. The only area where it is still lagging by some distance is depth of field, or rather the lack of it. A speedbooster would solve this issue, and I'd love to shoot real 85mm 1.4 street shots on the CL...

I'm not sure I know how to shoot "street" with an 85mm f/1.4. Most of my best street work is at focus distances of 6 to 10 feet, and an f/1.4 lens at 10 feet has only about 4 inches of DoF to work with on FF. That's barely enough to cover the distance from nose to ear on a face! On APS-C, the same lens (with effective focal length due to the crop of 128mm) has even less DoF; the Macro-Elmarit-R 60mm f/2.8 lens, that nets you about a 90mm effective FOV, nets about a foot's worth of focus zone at the same distance—much more comfortable for street work by my reckoning.

I tend to use f/4 to f/5.6 with a 50 to 60mm lens on APS-C format so that I have around a foot and a half to two feet of DoF to work with. Actually, the 43mm f/1.9 that I use so much of the time is a superb street shooting lens...

Nice. Would be using it for subjects very far away (full body shots) down long streets or alleyways in order to achieve a decent blur pluus background compression. Can do with the 50mm 1.4 on a full frame but would be nice to do the same on an 85mm equivalent APSC...
