Canon TS-E 24 II v 17mm

At f10 or so, I doubt there is any difference. Where the 24 really shines is being tack sharp corner to corner on FF from f3.5 onwards.

I am confused. I thought you just posted samples from a 1.6x sensor that were not tack sharp in the corners. I apologize in advance if I have misunderstood the thread.

No, the samples above were from the 24TSE II on the 5D2 @ f11 three shot stitch (an effective 17mm lens). I meant that I almost never go that wide (that shot was to test the performance on FF with full shift), hence why the 24 TSEII stays on my 550D most of the time. I posted some 100% samples from the crop camera in another thread, and the corners are just fine.

It really is a bit frustrating: when I want something better than my old 24/2.8 for stopped down landscape photography, Canon forces me to buy a TSE that I don't really want or a crazy fast 24/1.4 that I most definitely don't need.

cool down - the TS-E 17 is so good that this kind of force is easy to bear :-)

Here is a shot (stitched from three frames) with my TS-E 17 at f/8.0 on my 5D II (resulting in a virtual 11 mm lens) and the 2nd image is the top left corner as 100% crop - my TS-E 17 is tack sharp from corner to corner even fully shifted - that's a very nice lens (maybe one of the best ever built super wide angle lenses to date) - I'd personally never go for the TS-E 24 if I'd buy only one lens.





The corners are even fully shifted very acceptable!!

The best aperture is f/8.0 for this lens - I guess Canon is preparing for higher Megapixel counts and thus f/8.0 will give headroom for up to 50 Megapixel - (stitched from four frames this would give 1x0 Megapixel images - very nice outlook!!

And don't forget you can also use the 17 with a 1.4TC to get near as 24mm - quality I would say is about on par with my 24-70 - I only did a very quick test for someone else but I'd say the corners are better than the zoom but the centre was perhaps not quite as good. Even shifted it was pretty good.

There's simply no two ways about it, having both TSE 17 and 24 is very nice :-)

This is the closest I've ever come to feeling like I can really create technically superb landscapes, the creative limitation of course being me. Film in a Hasselblad never gave me results as good as I'm now getting with the 5DII and TSEs.

I know exactly what you mean. I had a Pentax 645 and it was a super camera, lovely to use and they make great lenses, but the 1DSiii with a 17TSE is definitely a good step up. And of course I could only dream of the equivalent of a 300 2.8 on the 645! ;-)

I agree. For the edge of the extended image circle this looks amazingly good and probably better than in the crops from the 24TSE shown by CW.

How much light falloff do you get fully shifted and how did you correct it in your stitch?

Well, I'm not quite convinced.

From all I've seen, my 24/2.8 is probably as good as the 24-70/2.8 at 24mm. The 17TSE with the TC becomes a 24/5.6 monster that can't take filters and is probably not much better than my trusty 24/2.8... ;-)

I think the better approach is probably to put a smaller pixel sensor behind the lens if a smaller FOV is desired. But it would indeed be interesting to see some comparisons.

I only use PS CS4 for stitching (reposition) and then crop it and save it back to PS LR3 - compensation for vignetting is roughly 70% - CA is compensated with remove all corners in PS LR3

That's it - then normal optimization in PS LR. Images are simply stunning - and before you buy a 2nd body with a crop sensor (as one post suggests) just wait fpr the 3x Megapixel pendant for the 5D II

I am already waiting for more megaPixels - the lens can surely utilize more of them ;-)

Currently I get with four stitched images some 52 viraul Megapixel. Here are some examples from last weekend with my TS-E 17 and tht 5D II (always f/8.0)

hope you get an impression of the lens

Well I can't speak for the quality compared the 24/2.8 but, of course, unwieldy as the 17 and 1.4x may be, it has the advantage of being able to tilt and shift :-)

I'm not sure if this will give you a good idea of IQ but this is a shot with the converter and tilted about half a degree to get back to front DOF. It was something I took in a hurry when comparing this to an Oly 35mm shift lens I was trying out. The image has lost a lot of quality for being compressed into a not too huge jpeg but I hope you can judge great corner sharpness and good DOF here. I won't embed it as it's a rather large file.

Your link doesn't work for me.

The-Digital-Picture has crops from both TSE lenses, including with full shift and TCs. After looking at those I think the two lenses perform really very similarly well. However, they show only single corner crops at the edge of the extended image circle (full shift) and there will be most likely some copy variability due to decentering.

FOV with both lenses can be made wider with shift-stitch or narrower with a high MP crop sensor or a TC. The best advice is probably (as always) to buy the focal length with a native FOV that you expect to use most often. That would be 24mm on a 5D2 for me.

Well, you must be very patient. The > 60 MP Canon full frame sensor will most likely not appear earlier than in a few years. And I have the extra crop body already.

Your photos are great. For these interiors the 17TSE really is perfect.
 
Wonderful.

As per post below, if you just take out the ~ either side of the link, it will be fine - I was just making sure it didn't embed the picture.

But, if you feel 24mm is what you'd get most use out of, then as you say, I'd go with that. I find I need and/or want an UWA lens enough for the 17 to have been the better choice for me. Though I wouldn't mind having both!

At the current pace, we won't see such a camera until 2020 I suspect. 1Ds series (3 year intervals, followed by 5Ds with the same pixel count) will probably have 30-40-50 MP iterations in the meantime. If (like me) you are willing to stitch, you already have a $800 50MP "FF" camera at your disposal.

It seems like this would be a good option, to have a tripod mount on the lens. Then you could do shift pano shots by moving the camera instead of the lens (which is apparently better according to some review sites, just tricky to do).
 
The lens has two rotations built in, one immediately after the mount but before the shift, the other between shift and tilt. I can't think where a tripod mount could be introduced that wouldn't compromise the flexibility of movements currently possible.
