Title: Trying my TS-E lenses at 187MP on the S1R
Post by: keithcooper on June 06, 2019, 03:14:47 pm
Panasonic UK kindly lent me a new S1R to try out - whilst the native lenses I tried (24-10 | 50/1.4 | 70-200/4) are fine, I was keen to see how the 187MP multishot mode would work with my TS-E lenses via the Sigma MC-21 adapter.

Anyway, the stuff has gone back and I've written up some more general review notes on using the camera, including the 187MP mode.

A simple up/down shift and stitch gives me a square 250MP image that would print at ~60" x 60" (@300ppi)

As someone shooting my day to day work with a 5Ds I'm quite impressed, although I'm told by our finance director (aka Karen, my wife) that that is not enough excuse to get one :-(

What a great review about the S1R. Canon TSE glass in use is always a very interesting read. Nice images all of them.
BTW, I found most of these pictures to have some good 3D pop. Is it that you have a secret recipy to get it or there is something special about the S1R sensor?

Thanks for the review Keith.

Thanks for the review!
Indeed, the Bayer matrix is the next problem to tackle since lenses can do so much more than they can show now... at least in the central area.
Now camera have become almost completely optical/electronic, the mechanical departments may put effort in moving the sensor at high speed and precision.

Very good article!

How long did a multishot-image take from fist shot to the ready image? (about)

I was interested in the Sony A7r3 because of the multishot, but have been unsure
because the files needs to be combined in the computer. When I saw that the Lumix
does this in the camera, I was very interested.

Thanks - I forgot to time it, but 5-10 seconds seems to be what I recall. The RAW files are suitably huge as you'd expect, so there's a bit of a delay writing to the card, as well as the processing.

For outdoor use, the mode that accepts some movement in the scene is a lot better, giving you the really high res on static items, but coping with things like leaves moving - where the drop back to single shot resolution is difficult to spot.

Do you believe the S1R will have better image resolution than the new Sony A7RIV while both using pixel shift for landscapes? Especially when implementing mode 2 on the S1R.

I've no actual data, but experience with the S1R definitely showed how useful mode 2 was for non studio shots. A lot will depend on how the Sony software adds the component images together.

But in the real world I do have to ask if anyone will notice ;-)

Excellent as the multishot mode was it raised lots of other questions for me...

In looking at my 187MP test images I was struck by just how good they could be and how much care it will take to get the best from any such setup. 

Even using the excellent TS-E50 lens and a hefty tripod I was getting variable results when looking at the finest (outdoor) detail. I'm minded to think that the number of people who will get genuinely effective use out of the multishot will be a distinct sub-set of those who try it. I'm not even sure how often I'd choose to use it myself, and I do architectural work as part of our commercial photography (having it as an option would be nice though).

Currently I'm using a 5Ds for most of my work and 50MP gives me images that are rarely too low resolution for client use (sometimes just the opposite). In terms of print size 50MP gives an amount of detail that easily makes for any prints people are likely to buy. Sure I like the idea of giant prints (largest to date is 47 feet long) but I quickly realised that people willing (or able) to display such stuff are in short supply here in the UK :-(

Of course my concerns won't impinge on the 'better' camera = 'better' photography mindset ;-)
That said I'm sure many may be tempted by 'never mind the subject/composition/exposure - count those megapixels'

Whoops, not what the camera marketing people want to hear - I'll get my coat ;-)

Glad you liked it!

Processing was actually just using ACR and CS6 after DNG conversion. I do a bit of sharpening for some images after reduction for web use, but for a review like this I try not to mess about too much.

The big 250MP stitched image and a few others had just a touch of contrast adjustment with Nik Colour Efex Pro (the pro contrast adjustment) but nothing excessive and mainly to give a better look for small web versions of what are big files.

Keith, I'm familiar with your great TSE lens reviews. I almost was going to buy one of the TSE shift adapters because of your review, but wasn't happy with my 24mmm tse image quality in the corners when shifted. I have opted to stich with the use of a panoramic head instead. Do you still prefer the adaptor when shooting with close foreground objects in the image?

Anyway, now after reading about the S1R pixel shift options I am considering this along with the Sony A7RIV and the 5DS-R as my next camera. I know the canon is old but I have a lot of L-glass. Primarily I want to shoot landscape/nature and print large for maximum resolution. Any suggestions you might have would be appreciated.

The TS-E24 definitely needs a bit of stopping down if you've important detail in fully shifted corners, although care in checking that there is no residual tilt in the mechanism is important. This takes some experimenting. Take two shots at full shift, with detail in the corners, rotate just the tilt axis by 90ยบ - if there is no residual tilt, the images should be the same. I keep the tilt axis of my TS-E17 and 24 well locked for most of the time, since I use tilt in perhaps 1 in 50 shots for my sorts of photography. I've heard of issues with field curvature as well, but it's simply not something I've personally seen.

Much of my shift/stitch approach with the TS-E24 is simple up/down pairs of shots to crop to a square image, so the TSE Frame is something I tend to use more indoors where I can see there are going to be parallax issues, or I've got stuff close to me in shot. If I want left/right stitching for width I'm more likely to stitch multiple panned shots, where I have a choice of non rectilinear projections if I want

The 250MP shots in the S1R review used the frame. The shots with the TS-E50 also used it, but that was as much as because I wanted to test the new version of the TSE Frame for the 50.
