Could the dual pixel “focus adjust” be used (theoretically) to algorithm correct a lens to a flatter focus field in post processing? Obviously it would require a lot of measurement work and software development.
Just wondering out loud.

I believe it could, yes. That would be a great application for dual pixel RAW, to correct the minor but predictable focus variance resulting from mild field curvature.

That got me thinking about stacking software that uses the two images from the dual pixels. They can be recovered using DPR Split, and stacking software should select the portions of the two or three if you include the combined image.

Thank you for all the responses, they've been very helpful. For her I think she will take a combination of indoor, outdoor and fast/sports shots, so I suppose an all-round good DSLR would be important. From the comments here and from what I've read, it sounds like the 70D may be more than enough camera to start and may be something she can grow into with time. As some of you mentioned, worst case the camera can be sold at a later time.

Thanks again for all the help!

Thanks for the suggestion. I’m a bit of a hoarder so sometimes I need a push to get things out the door one way or the other.

Still have some FD lenses and three film cameras that I’ve not touched in ten years other than to push them aside to get to other stuff. Also leave them out as decoys when I leave house for any length of time.

yes, but interest and demand for soft focus lenses seems a bit ... soft.

My 80D's grip is quite solid for sure, this one surely looked like is was busted somehow, probably was dropped and hit the floor hard right on the grip....

The sharpest lens I have ever used is the Nikkor 50mm F2. Many people say the same.

I often get moiré below the eyes or the hair when the focus is spot on. I attached an example 100% crop. The photo was taking with a 650D and opened in Photoshop with standard settings. I usually take photos at F4-5.6 but I think it will look about the same at F8.

Hello,
I can highly recommend the Sigma 17-50 EX 2.8 lens.
This is my always on lens, it can be used for almost everything:

Family shootings, weddings, landscape, sports...
(In case of sports I shot my brothers team at handball, in a poorly lighted gym.)

For 300€, it is a lot of lens!
The only thing which is a pain is video recording, at least if you record audio close to the lens because of the quite noisy autofocus.
For this I bought the 100€ 18-55 STM lens. However it is not as sharp and versitale as the Sigma.

Cheers,

Stefan

Cheap umbrella, cheap stand, good old fashioned sync cable. Once you know you need wireless the Yongnuo YN600EX-RT lights are good enough and cheap enough to mess with for a while until you figure out the next step after that.

Also have a look at strobist.blogspot.com

Sony sites rumor to see an Sony A6700 to use 31.49MP IMX342LQA Global Shutter APS-C Sensor.

That would be fine to see it in an MLS body from Canon too. Electronic curtain. 10fps without distortion of objects.....
Silent birding... 31MP crop... mmmmhhhh for small birds

LensTip posted sample images, so we may have a full review soon.

Thanks for the info, those samples certainly seem quite decent.

This lens is sharp, probably as sharp as my Milvus 100, but it does not have the microcontrast that the Milvus has. But it has AF and I have not yet decided how good that is for macro; more evaluation is needed. I remain surprised that I would even consider AF for macro. I like this lens a portrait lens using the AF.

The disappointment so far is the MF; a firm twist throws it far out of focus and a slight turn usually overshoots. I miss the consistency of a direct connection, but I will continue to practice. But I doubt that I will ever purchase another focus by wire lens.

So typical focus by wire quirk exists even with this lens.

...Canon is unlikely to hit this level on the first iteration so they will probably be pragmatic and be happy initially with something to make the statement "we can do it too"...

Click to expand...

I've seen this reasoning a lot on this forum and I don't understand it. Why would Canon not want to hit it out of the park on its first attempt? And, why couldn't they?

They certainly have the resource available. And they've no doubt been researching this for years. I'm not suggesting that their first full frame mirrorless with be the perfect body for everyone. There are some baked-in decisions that will be guaranteed to disappoint no matter what they do (lens mount for example). But, I find it very unlikely they will unveil a "beta" version and in effect say, "we'll do better next time."

Click to expand...

The reason I am a bit sceptical is that there is a difference between designing a product and it working out as you intended in the real world.
Added to this, Canon is very cautious about releasing new technology - it seems to me that if there is any doubt they prefer to hold back a bit until something works with a high degree of confidence. Their main marketing drive is making cameras that professionals use and as a soldier says, a rifle that works intermittently is worse than one that does not work at all and I think that thinking has got into Canon's DNA.
Yes, the M series started off a bit of a lemon but that was aimed squarely at the lower end of the market, but I get the idea that with their first FF mirrorless they want to aim more upmarket and that means it must work.

Click to expand...

I get that, but canon does not need any new to them technology. They have arguably the best on sensor auto ficus system; they know how to make an EVF. What else is there really? Hell if they want to do something special, they know how to make a global shutter too.

I expect them to do the smart thing, which is to go up to the widest market they can capture. That’s not the high end, and it won’t be a spec sheet warrior, but there is no reason to assume it won’t be well thought out and put together.

Click to expand...

Canon has shown they are closer to building a FF mirrorless camera than a lot of people give them credit for and more closer to FF mirrorless than Nikon.

They have technology based on previous APS-C mirrorless tech:
- DPAF with full touch screen menu and focusing
- EVF from M5
- eyeAF from M50
- Ergonomic, menu & build quality from DSLR
- global shutter

Canon can really come out with a really compelling FF mirrorless this Sept if they are aggressive. Pent up demand with enough features at compelling prices will drive a lot of sales even if they decided to go with a new mount (backward compatible to EF lens via adapter close to 100% native).

- 26-30 mp sensor that's an improvement over 2 yo 5D IV
- improved EVF from M5
- improved eyeAF from M50
- ergonomic, menu, build quality, color science similar to 6D
- dual SD
- fully touch screen.

If they can add global shutter, IBIS, or comprehensive video features, it will definitely a success.

Click to expand...

the M50 is killing it in Japan, do they even need to do that much?

The 5D Mark IV sensor is very competitive as it stands, they don't even really have to improve that much on it. just make it faster, and less power intensive.

Click to expand...

Canon APS-C Mirrorless is very successful in Japan except world-wide. I think Canon would like a debut their first FF mirrorless not like a first generation product but a more mature and well-thought camera.

I don't think what I'm asking is too much. I don't expect global shutter sensor or similiar ISO/DR as Sony sensor.
They already a great camera with Canon 5D IV and existing APS-C Mirrorless and that sensor is more than most photographer needs for a 2 years old sensor. I'm sure they can refine the sensor even more.

Click to expand...

your phrasing was confusing then because it sounded like you thought they *needed* to have global shutter, IBIS, or comprehensive video features, to be a success.

I took it out for avoid confusion. It doesn't need global shutter or IBIS to be successful. A decent video feature may be needed to be competitive for hybrid shooter and if they are demanding $3000+ up MSRP. No way Canon can only deliver Canon 5D IV video features in 2018.

chrysoberyl · Jun 25, 2018

I like this pickle jar; it's so big I think it has it's own gravity. It will be hard to misplace.

But seriously, this thing is almost as sharp wide open as my Milvus 100 wide open. I hope I get some clear air soon for astro. And focusing is a delight; a well-damped focus ring and a reasonable amount of throw.

They seem to be a very stable company.

don't know for the company, have not seen their financials. but it certainly applies to their products. ;-)

anything i purchased from them was really right for the intended task, but also "really expensive". especially once import duties (drüending on item! up to about 10%, in the future maybe more ... oO) and incurred import sales tax/VAT (20%) on "cost of goods plus shipping" (!) were added. i've given up on purchasing camera-specific plates after having to give them away as a freebie when i sold "outdated" cameras in the past. their tripod prices are so sky high that i am not even willing to consider it. in the same line as i was never inclined to buy expensive 100% oxygen-free copper monster cables for a hifi system. nice, but over-engineered for my needs.

In response to the OP's question 3, the 16-35 F2.8 III and the 24-70 F2.8 II are both very good lenses, but they are both heavy and there is a lot of overlap. So, one question might be how important is it to close the gap between 35 and 70, figuring in the possibility of zooming with your feet, stitching and cropping.

Or the overlap between 14 and 24?
I remain happy with my Samyang 14/2.8, especially because of the lack of coma and its pretty sharp wide open. Photoshop corrections remove distortion and vignetting (with a little extra noise).
Looking at your shooting stats and your current kit, I'd take the 14/2.8 and 24-105/4 hiking. I do. This covers most things for modest weight.
This option is probably the lightest weight. And the cheapest!

@Michael Clark - I think that dual pixel AF is actually pretty decent when there is enough light. It still struggles a bit when it is darker though, and the raw speed on a DSLR in live view is still very slightly slower. I was pretty impressed with m50 AF speeds, given the price.

Because Canon doesn't yet have a pro-ish MILC yet, we don't have advanced af modes with dpaf yet, so we will soon see how that pans out.

@cfb - lol as they say, a picture is worth a thousand words.

Apparently it got taken down.

It was an interesting day. A lovely young woman didn't say anything to me, but it seemed apparent she was posing by a fountain. A young black guy walked up to me and said, "Take my picture." So I did. He asked what paper or something would the picture be in, and was a bit disappointed when I told him I was just having fun. I had just the camera and the one lens, but that must have been enough to make him think I was a pro. So I didn't have to approach people or sneak pictures. I still have a couple of 11" x 14" prints from the day.

You know, you can’t tell this story and not post a scan of these

I'd agree with most of these posts, the 40mm f/2.8 Shorty McForty or the Tamron 45mm f/1.8 would be great choices, well ahead of the EF 50mm f/1.8. My daughter lucked out with a second hand one for $40 which is a genuinely decent copy. The 50mm Canon is certainly a cheapie, and you might get lucky with a good one, but somewhat random copy variation might play a negative position for you.

If budget constraints are tight, go for the Shorty McForty pre-owned. They're a rock solid little lens with a huge following.

If I recall correctly, Lensrentals has found the 50 f1.8 STM to have excellent, almost non excisting, copy variation.

Click to expand...

+1 You are absolutely right that it is incorrect to imply a large copy variation for the 50mm f/1.8 STM as the opposite is true. This is what Lensrentals writes: "Remember, the Canon 50mm f/1.8 STM is the standard against which all other lenses are measured. It’s amazingly consistent." https://www.lensrentals.com/blog/2016/05/sony-fe-50mm-f1-8-mtf-and-consistency/ (they have the MTF variation of the Sony compared with the Canon 50/1.8)

Click to expand...

Let me correct something I said earlier.....

The OLD version of the 50 F1.8 has terrible AF inconsistency.... the STM version is much better. The old version can be found used for almost nothing, and is not worth the price.

The original f/1.8 is an excellent lens with a metal mount. I had one from the film days which I sold for about $150 a short while ago after I bought the STM. It was replaced by the version II, which would break into II when dropped.

Improvement yes, substantial no.

There are multiple small improvements, but it is not a leap.
- the unit is lighter, which helps with handheld imaging.
- lower power setting is good for z-stacking with open f-stop. Had to use ND filters on MT24. I also used it as a trigger flash for a UV modified Metz 45 CT1 with optical slave, and there the negligible light contribution from the MT26 @1/512 power is an advantage as well. Now upgraded to a Buff Whitelight 1600 UV and that is radio-controlled.
- The Canon diffusors clip onto the unit, so do not fall off, and are a bit smaller, so less chance of touching specimen.
- Diffusion strength is a tad better, but not by a large factor. If you use the unit for close-up (1:5 to 1:1), then you may still want to Frankenstein the diffusors, or do something else, like fill light, reflectors, indirect lighting, etc. For close-up I prefer using either studio flash with small softbox, or use my 580 on a Flashzebra cord through a Westcott diffusor and reflector on other side.
- I shoot mainly 1:1 to 5:1, and there the reflectors are effectively a "large light source"; see Hunter & Fukua "Light: Science and Magic". For that the stock diffusors are more than adequate.

The MR14 is a ring light. Never liked those as they produce very flat light. Got one back in the OM days as a feebee, but only used it one day for playing, then went on the shelf. The adjustment options on the MT24/26 will take some time to understand: Rotational angle of reflectors, inclination angle of reflectors, overall power and flash exposure compensation, left-right power distribution. For instance, directing flash not directly onto subject, but only hitting it with a peripheral glance, produces much softer light, and helps with foreground/background illumination balance.
Diffusion is important, but the other factors are equal if not overall more important. Take your time playing around with the unit once it arrives. Put camera on tripod, fix everything onto one object, then start taking lots of pictures (2-300) with all sorts of adjustments of nothing but the flash.

Re your question of improvement, the MT26 will be a substantial improvement over the MR14.

Hope that helps.

Thank you Zeidora

I'll printout the above to read and re-read until everything sinks in.

I've a feeling that moving from the RingLite to the Twin Lite will improve my macro images substantially

Once again, thank you for the feedback
