... I get it that a
17mm tilt shift is a specialty lens but so is the 24mm tilt shift I had no trouble selling locally a few years ago. I guess times have changed rapidly. Maybe I should have kept my 5D III and kept using it.
While they certainly are depreciating a lot from their original retail price, Tilt Shift lenses should still retain their value reasonably well... at least for the time being.
There are no TS being made for the RF mount yet.
And existing TS-E are easily adapted. In fact, adapting them with one of the adapters that accommodate a drop-in filter offers some new opportunities, especially with a lens like the TS-E 17mm that's very difficult to fit with a filter. There are quite pricey Canon OEM EF to RF drop-in filter adapters... much more affordable Meike (where some reviewers feel the Variable ND is superior to Canon's), as well as a couple others, plus an array of filters for them.
While the TS-E 24mm, 45mm, 50mm, etc. all can be fitted with filters much more easily than the 17mm, doing so may limit the lens' movement... so the drop-in adapter can be useful with them, too.
There are rumor of some future TS lenses coming from Canon for the RF mount. A TS-R 14mm f/4 and TS-R 24mm f/3.5 have been on the Canon lens roadmap for some time. There also have been hints that they might be the first lenses to feature autofocus, though that may be a bridge too far. I expect Canon will eventually port over the other TS-E lenses to the RF mount. No need to completely reinvent the wheel.
Tilt Shift lenses certainly are specialized... and quite expensive. A lot of photographers buy them for a job, then sell them off after they find limited additional use for them (might have been better to rent). But, as a result of this turnover, there has been a moderately robust used marketplace for them and unless a new model was introduced, they tended to hold their value pretty well. Personally I've still got the 24mm and the older 45mm. I had the 90mm, but sold it some time ago (and kind of wish I hadn't). I've probably used the 45mm the most... small product photography in studio.
I've seen some outliers... such as a TS-E 17mm that sold for $700 recently (an under-priced "Buy It Now" on everyone's favorite auction site). But that lens, which sells new for $2149 at retail rarely sells for less than $1200 used, and in very good condition often brings $1400 and $1700.
It appears Canon has discontinued the TS-E 135mm. It's shown as "out of stock" at Canon USA and no longer even listed at B&H website. They both still list the TS-E 17mm, 24mm, 50mm and 90mm. But only the 17mm and 24mm are in stock. The 50mm and 90mm are shown as "back ordered" at Canon USA. At B&H the 90mm is listed as "temporarily out of stock". I wonder how that differs from "back ordered", which is how they describe the 50mm's status?
Cheers!
