We have been told that a zoom fisheye similar to the EF version will be coming for the RF mount. It will be an “all-new” optical design and will work just fine on both crop and full-frame cameras. The EF 8-15mm f/4L USM was quite a popular niche lens, and we'd expect a similar focal length and speed in the RF variant.
Currently, Canon only sells the RF 5.2mm f/2.8L USM Dual Lens Fisheye for VR/AR applications, at least that is how it is being sold and marketed. We haven't seen too many people using it for stills applications.
One of the strength of the EF line-up was the “niche” lenses such as the zoom fisheye, the MP-E 65mm and probably the best tilt-shift line-up of any manufacturer.
We know new tilt-shift lenses are coming and they will somehow have autofocus, and I received further confirmation of these lenses coming in the last couple of weeks. Though a timetable for launch is still a mystery.
The MP-E 65mm f/2.8 1x-5x had a lot of fans, and we expect Canon to address such a lens in the future, but we haven't heard anything about it from any sources.
Once we have a bit more information about the coming zoom fish-eye, we will add it to our roadmap.
A 180 macro with optical stabilization would be fine! A 50-60 macro too!
I personally can't see what a RF version can bring to the table except that it gives Canon permission to kill off the old ef version in 5 years or so.
There are a few niche ef lenses that really do need a warm over. These will never see the light of day as mk II ef lenses...so my only hope is that thye will be RF lenses instead. The ef 180mm f3.5 L macro is another of those niche lenses. It's far better than any other variant of it's type from any other brand. It's not until you try the Sigma, Nikon, tamron etc until you realise how good the Canon variant is in comparision. But it could do with newer optics, coatings, AF motors and yes...a modern macro capabile IS system. However, the EF version is so niche it still commands a high price...I shudder to think what Canon would charge for an RF version!
If canon were smart with their TSE-RF lenses, they would include a rear drop in filter slot. That would level the "features" playing field between ef and rf variants.
I like the idea of a super wide f1.2 prime lens. Looking at the block chart...that's got some seriously funky glass shapes in there...that isn't going to be cheap or light weight!
Absolutely! I love my EF version and use it at every wedding. I will be upgrading when the RF version comes out. As stated in other posts, niche lenses like the fisheye, MP-65mm and tilt-shift varieties are what makes Canon special.
Interesting because i heard exactly the opposite from a pro photographer who sold the Sigma 180mm macro for the Canon version and said it was not worth it.
don't forget about effective aperture though. you'd be blasting those animals with laser light to get a bright image...
What version of Sigma 180mm lens were they using? I know quite a lot of butterfliers who still use their Sigma 180mm(2.8 and old 3.5) and they are very happy with their lens(with 2.8 common complaint is the weight). Unfortunately all 180mm lenses have been discontinued(though they seem to be fairly common on used market), given Tamron was quite old by the time Sigma updated their 180mm and it was choice between heavy 2.8 with stabilization but no Weather sealing vs Canon's 180mm macro without OS but with weather sealing and light on back.
Add NO focus shift as well otherwise that wishlist is what any new 180/200mm Macro lens should be.
