p.1 #1 · 17mm TS-E, 1.4X Extender, and Various Sensor Size


If anyone else has A-B shots using the 17 TS-E and Extenders, please feel free to post here.

These shots taken today are the first time I've mounted the Extender behind the a TS-E lens. From the reading I've done, this Extender (and the 2X, as far as I know) can be used with any of the TS-E lenses.

One thing different from using the Extender with a different lens like the 100-400L, is that the actual focal length is not shown in LR4 -- it comes up as 17mm, not ~24mm.

So, here are the same shots switching out the Extender in the awful Santa Ana winds today! (Fires in Camarillo, CA are making national news.)

p.1 #2 · 17mm TS-E, 1.4X Extender, and Various Sensor Size


Here are the next two sets.

In all cases, I found the 1.4X caused over-exposure by around 2/3 stop. It can be seen in all the exif data here. I made corrections to the exposure and general PP for color, contrast, and sharpening.

Overall, the addition of the Extender didn't demolish IQ/resolution, but it did noticeably lower it a bit -- coming out just a bit better than if the 17mm image had been cropped to the same size. Of course noise and grain structure is improved by using the 1.4X and not cropping, so it is a trade-off. Certainly lighter to carry a 1.4X instead of the 24 TS-E II.

Nice.

I'm of a mind that if I get another tilt/shift, the 17 would be ideal because it works well with the 1.4X. That would basically provide a 17 and 24-ish mm tilt/shift lens. Very good image quality, and very versatile.

I have posted a comparison between the 17TSE/24TSE/24TSEmk2 with raw files, including the 17TSE with a 1.4xII converter, on 5D2. Just grab the raw files, use your raw converter of choice, and see for yourself how good the 17TSE + 1.4x is!

Stan -- Thanks for posting the files for comparison!

Tom -- Sounds like a good plan.

I'll try to post next week some detail shots from some or all of my examples.

Thanks for the comparison, Jim . From what I could tell, unless you shift quite a bit, the resulting IQ with the 1.4X TC is more than just decent. I didn't see any indication of the fire in Ventura County judging by the blue sky though .

Joshua -- Thanks!

You can see the fire clearly in the bandstand shots, right side, facing SW -- looks like a low cloud, but it's brown/grey.

The quality seems good with the Extender. I no longer have the original 24 TS-E to compare against, but sharpness seems similar without as much CA, maybe a little better, going from memory. Certainly convenient!

Thanks for the comparison Jim. I did use the 1,4x a few times when I bought the 17 TSE. But after a while I bought the 24 TSE also. The IQ is rather good with the 1,4x.

Strange. I just clicked on it and it loaded. Note that my server did have an outage and you may have hit it at the "right" time... Let me know if it's still busted.

But why Canon says "..This tele extender can be used with fixed focal length lenses 135mm and longer (except the 135mm f/2.8 Softfocus lens), and the EF 70-200 f/2.8L, 70-200 f/2.8L IS, 70-200 f/4.0L, and 100-400 f/4.5-5.6L IS* zoom, EF 400 f/5.6L* lenses..."

Because this quote is old, it pre-dates the 17TSE (it doesn't mention the two new 70-200 lenses either, the 70-200/4LIS being relatively pretty old).

My understanding is the combo is better than the 24TSE Mk I but not the Mk II. A lot of fine work was done with the MkI. I have a lot of 24s-just not TSE. I can always tilt in PP. So, especially for travel the 1.4x and 17TSE is the combo for me. Also since the TC uses only the central portion of the lens' huge image circle I would anticipate you could tilt and shift more W/O aberrations.

I've never noticed that the 1.4X causes the 17TSE to over expose. But alas, Its usually in manual mode anyway soo

Thanks for sharing these. My only beef with this combo is added distortion. When I shoot architecture, I frequently end up with verticals near the edge of the frame, and there's no doubt the bare 24 is miles ahead in those situations.

Take away those verticals, though, and it's one heck of a money-saving combo!

Did you shoot from live view mode? Shifting, and to a lesser extent tilting, confuse the SLR metering system. In live view mode exposure is calculated based on what the sensor sees and should be more accurate.
