How to defish architectural shots made with Canon EF 8-15mm f/4L?

Hi,

I am trying to use Canon EF 8-15mm f/4L to make some archictectural shots (façades of two or three story buildings in narrow alleys and very long façades in narrow alleys as well). What do you recomend to defish those images? I have already used my widest rectilinear lens (Sigma 12-24mm) but I still need a wider field of view, so I think a fisheye will be my best option.
Personally I find stitching better than defishing. But when I want to defish I use Fisheye Hemi https://imadio.com/products/prodpage_hemi.aspx I like it particularly because it maintains perspective but straightens verticals. Take a look at it and the examples to understand what I mean, normal rectilinear corrections cut huge chunks off the corners and drag out the view in the corners so much they are not worth having.

Although it is a basic plug in there are many tricks you can do that will increase its utility and the output you get from it, you can even apply it twice to get full rectilinear, there are some great tutorials on YouTube. https://www.youtube.com/results?search_query=fisheye+hemi

Patent: New Consumer Level Zoom Lenses

i cannot see Canon adding f/6.3 lenses to EF portfolio all of a sudden, when they have avoided this for 30 years. For good reason: AF limitations beyond f/5.6 on most EOS DSLRs.

i could imagine f/6.3 lenses for R mount, because mirrorfree EOS R series cameras will/should be able to AF to f/11.

Whether or not f/6.3 is a "desirable open aperture" at 60 or 70mm focal length is for each potential user to decide. I don't think the difference in size, weight and price between a 16-60/3.5-6.3 and a f/3.5-5.6 are so huge to make it worthwile.

this said, i currently do own and use one Canon f/6.3 lens, EF-M 55-200 and have also been considering EF-M 18-150/3.5-6.3. Nothing else available from Canon and size/weight, focal length range, price make it "borderline acceptable" to me. Although i would really prefer f/5.6, especially on APS-C.

I own all current EF-M lenses except the new 32mm. The 18-150 in particular is a super zoom lens. The 55-200 is the lens I use the least.

Review: Canon EOS R by Peter McKinnon

What I appreciated on McKinnon's vlog was that he talked about the downsides - contrast that with someone like Jason Lanier reviewing at Sony and he absolutely refuses to say anything negative at all about the gear.

Jason Lanier comes across with a 'my way or the highway' style I do watch him sometimes even though I don't enjoy his presenting manner! If I had to nail it down to one reviewer then it's Dustin Abbott for me, I find his style less flashy and more honest/reasoned, it's not so much about him the person more about the way he presents his view, he choses not to slate something but explains in-depth the pros and cons of a particular piece of equipment, so the content of his work really make sense IMO and if you watch his youtube review of the Canon 50mm f1.2 you'll see what I talking about...

Canon officially announces the Canon EOS R system

That seems to be a running issue with mirrorless cameras and may come about by the push for smaller sizes - smaller size means less real estate to put buttons and dials and what buttons you do use are either large with a positive action or small and squishy. So they usually end up with a reliance on menus with ability to program a few buttons in a way that suits the user (aayhay! look how customisable it is) I think Fuji have got the balance best but it can't be easy to design

Question on High-Speed Continuous Shooting using an EF prime or zoom lens

My 5D MK IV seems to me to produce too much noise, I don't think it is any worse than my MK III was, but perhaps a different texture of noise. Obviously, a APS-C sensor is going to have even more noise, its definitely a issue in low light.

This "issue" my body is suffering from in another way. If I take an HDR with 5 pictures, the gap between these shots must not exeed 0.5 stops. Otherwise, really big noise appears. But interestingly, not the dark pictures create this noise - the lighter ones do creat noise like clouding.
Some friends of mine do own 5D4 too, so we compared the bodies. And mine is the only to suffer tis "issue" from. Also, the sensor is giving me soft picturs. Fine for portraits, bad for landscape. CPS told me, my sensor is really creating soft pictures, but this no such an big issue that it has to be solved by an hardware exchange.

Fuji's next Medium Format "more affordable"

The early information is looking like it will be a very interesting camera. They're trying to provide some performance along with all those MP so a few might show up at sporting events where long lenses aren't required. Even if not, better AF performance is needed to put the thing into use for fashion and faster studio work.

I kinda hope they also add pixel-shift resolution enhancement... Just because I want a 300 to 500MB raw file to choke my editing machine with crazy amounts of detail.


Well , from your lips .... A GFX100S model is coming in 2019. 100 megapixels! :p
Rumored $10k price tag.

Panasonic announcing Full Frame mirrorless !!

Oly's press release event was painful to listen to (because it was info sparse and very slow paced) but they intend to focus on high performance small systems and I think they'll have more of that market to themselves soon enough. Their flagship is still my favorite camera to use, fast comfortable and well-featured and the IQ is PDG for a smallish sensor.
If they drop an even faster shooting body with global-shutter sensor into a high end body like the EM1 for their anniversary product in 2019 I'll be on it.
Lots of great lenses in the MFT suite but still waiting for a wide TS option.

Pentax had a very good mirrorless APC years ago. the K-01. Ugly brick of a camera but it worked well with the native K-mount legacy glass. Pity it didn't have even a bad EVF, the rear display was nearly useless in daylight. Their tiny q-mount cameras actually deliver pretty good IQ again for a PnS size sensor, lots of useful features and dang, they're just plain cute! Again, handicapped by lack of EVF.

I haven't played with a Ricoh GR but they have a passionate fan base.

Pentax K-1 is a lot of camera for the $ and IQ and build quality is top notch with more features than you can shake a smart phone at.

What these companies seem to have in common is a lack of marketing!

Venus Optics unveil 8 new & unique Laowa lenses in Photokina, including the 25-100 T/2.9 Professional Cine Lens

What is the pricing likely to be on the Laowa 100mm? I don't have a real sense of how they price their lenses.
I hope its around 650$ mark max their 25, 15 and 60mm macros are priced very aggressively for the features they offer. Also for this new lens they have adopted electromagnetic diaphragm which might add 50-75$ to price of lens but its a good upgrade over their previous lenses.

Canon DSLR to screw mount adaptor info ?

Hi Andrew.
I’m guessing from what you have said that if you do have a programmable adaptor, any setting is accidental, you might have a look at the link, scroll down to the text just above the large pictures and the last couple of lines are how to avoid accidentally entering the setup menu, it might be worth having a look for reset!

https://www.ebay.co.uk/itm/CHIC-Ada...611831?hash=item25fdd876f7:g:uLcAAOSwciVbbqFb
Alternatively you could buy it for £8.50 and you can have one with a chip that works with a 5DIII, or if you are not in a hurry one from China for £3 that is chip 3.0 but doesn’t specifically say 5DIII (only 5D)!

Cheers, Graham.

So where is the EF version of the new 50mm f/1.2?

What about the 400mm F2.8L iii and the 600mm F4L that were announced earlier this month? Don't they count?

While these lenses are welcome updates of Canon's highest end EF lenses, they were likely in the pipeline for some time. I also expect that some of the updates help these lenses work better with the RF adapter, as Canon has already said that lenses released before 2012 will not take advantage of all available RF features.

The same tweaks for better RF performance might explain the strange case of the 70-200mm IS III update, which, otherwise, seems to be only a new paint job and less resilient lens coatings.

To repeat yet again, few posters here, if any, have claimed that Canon would immediately shut down production of EF lenses. I'm a Canon customer who believes that EF as the flagship, central lens mount for Canon is now in the rear view mirror. Yes, updates that cut production costs of existing, popular and very profitable per-unit lenses (such as the big whites) will still be released for a year or so. As said, these are clearing the pipeline during the transition to RF.

I think those who claim "hysteria" or "bias" against those of us who believe EF is now a legacy tech are actually arguing against a timeline, not a concept. Will the last EF lens be produced two years from now? Probably that is too soon. Five years from now? In my opinion, quite possibly. But, once again, EF lenses will be serviceable and worth buying after production officially ends because there will be many working EOS bodies circulating for many years beyond.

I think people who don't believe that RF will replace EF don't believe Canon has actually come up with something better, or that Canon would ever phase out something that has been around for 30 years even if RF is better for them and customers.

But I've also admitted in this thread that I might have overestimated the speed at which Canon is actually capable of making the transition, especially after reading the article with the general managers who claimed they simply didn't have better sensor tech or IBIS tech ready for the EOS R.

If calling my thought process "bias" makes you feel more comfortable during a time of exciting transition, that's ok. I will repeat my thanks to those posters here who have patiently explained why they believe EF lenses are still, generally, a good buy for quite some time.

EF, RF, Trolls and Children

?

I tend to agree with you.... in the long term, the M mount and the RF mount...

Tiny crop cameras, M mount.... no question about it....
Smaller FF cameras, definitely the RF mount.....
Larger FF cameras, over time I think more and more will transit to RF mount, but there may still remain a few EF mount cameras, even in 10 years time....

The interesting possibility that I have been pondering for quite some time is, is the crop rebel going to be replaced by the FF rebel? If you imagine an R mount crop camera, what does it really take to make it a FF camera? All you have to do is replace the sensor.... all the other electronics remains the same.... Now wouldn't that bust the bargain camera marketplace wide open :)

Yes, will be interesting if the future will contain more 'larger' M mount, OR - yes as you suggest "a crop sensored R Mount".
That the EOS R camera came out with the ability to use EF-S lenses (via the adapter) was something I did not expect...
But it actually has me excited it can. Particularly as I have a few EF-S lenses I love, and would serve well for photography (albeit at 12MP), as well as the current 4K video crop.

So I do appreciate, that Canon may have looked at the option of placing a APS-C sensor in an R mount mirrorless camera body. If that's the 7D, or a 'Rebel FF' (or both) - remains to be seen.

Cheers,

PJ

Your take on the second Canon EOS R body

I get the feeling that the body design is pretty much set in stone for any other variants.
I was very dubious about that touch slider control in bad cold/wet weather, gloved hands? No way Canon didn't consider that though.
On reflection I wouldn't go wishing for those old controls back too soon until you try the new layout.
Some very good points.

ICYMI: Nikon Announces The Crazy P1000 Compact With 3000mm Equivalent 125x Zoom

I got to play with a P1000 yesterday for a few minutes. It's huge, about the size of a 5DIV + Tamron 100-400mm. As the reviews so far are intimating, it's very difficult to use at 3000mm without a tripod or a rest. I checked out the resolution on a chart at a variety of focal lengths and compared with a 400mm DO II on a 5DSR and then on a 5DIV with TCs. As predicted, there is no increase in resolution on going from about 1500mm to 3000mm. In fact, it gets worse at 3000mm. I upresolved images to the size of the 3000mm one. 1600mm and 2000mm are better than 3000mm. 400mm on the 5DSR is better than 3000mm, and on the 5DIV with TCs, significantly better. The collage of upresolved images looks scrappy because the individual shots were taken 12m away from a tiny target at a size set to test the resolution in moderately shady conditions, and not designed to look pretty.

Panasonic-Leica-Sigma FF MILC development

Lens IS isn't a direct replacement for IBIS. In some cases it works better, in others it's not as effective. The best results get from combining both.

Canon color, especially for JPEG and video rendering, out of the box is great. But once you put your raw files into Lightroom you lose a lot of that benefit and the playing field is a lot more level. I frequently shoot with both Canon and Sony bodies at the same time, and when files are put into Lightroom and processed the color rendering is pretty much identical.

Lots of New mirrorless and DSLR cameras in the pipeline

Technological advancement normally comes with some penalties relating to power usage. Compare modern smartphones to pre-smartphones that would work great for a week or more on a single charge.

How often did you have to change the battery in your 35mm film SLR?

WIth mirrorless you're going to get shorter battery life than a DSLR for the same capacity battery. That's pretty much unavoidable. With a 128GB or 256GB card I find however much I shoot I'm pretty much not going to fill up the card in one day, even with full-size raw files at 50 megapixels.
