Nice colors and textures in your photo. I've evaluated this and the 24mm from CPS but can't decide which one to buy. The 17 + 1.4x III becomes a 24 with minimal IQ loss stopped down, but the 24 lets you use filters far more easily. Polarizers are pretty handy for windows and landscapes, but 17 is wider.
Anyways, even after two weeks with each, I agree, they are tough to use, particularly Tilt if you're using it to correct vs. artistically. Shift is easier, but the camera must be perfectly level on all 3 axes.
Congrats on the purchase and I look forward to seeing more work on this thread.
I´ve had some more time to play with it now and I´m slowly getting there. I find it easier to work with the 24 though, especially tilt, and as you say, it is more convenient also because we can use regular 82mm filters. I have not tried the available filter alternatives for the 17mm, but apparently there are things that work there too.
These two lenses are both optically and mechanically amongst the best I have ever used. But if I had to get just one, I think i would have voted for the 17mm. Even though 24mm is my favorite wide angel focal length for general photography, I find that I´m using the 17mm differently and I enjoy the wider view. I also enjoy the extra work pr. image you have to put in with these lenses. It is so much more rewarding to get a good image, when it took time to plan and set up.
I´m not sure I understand how you differentiate between artistically and correct though. Maybe you could elaborate on that.
