DP Review puts K-1 Mark II as second worst camera of 2018

It's painfully apparent that DPReview is, to be as generous as possible, biased towards a few brands. All the features that you mentioned, and it is not a complete list by any means, while definite real world advantages, are just not deemed to be important by them since their favourites don't have those features.

Bellows II + Slide Copier
Posted By Wheatfield

I had this issue when I was using APS-C as well. IIRC, I solved it by using the 77mm lens with everything extended as far as possible, and that was as close as I could get to usable results, and they weren't all that usable. In order to get anything that worked, the slide duplicator bellows had to be retracted and a light baffle that I made from black craft paper was inserted between the lens and the slide duplicator to get the required distance from the lens.
Sadly, the fact is, the bellows and slide duplicator are not going to work well with your APS-C camera.
My ultimate solution was the K1, but in the interim, I built a small light box with a cardboard frame on the opalized glass that the slide dropped into, and used an old enlarger that I had converted into a copy stand to hold the camera and belows vertically.
This worked far better than anything I was able to make work with the slide duplicator.
Full disclosure, I tried lenses from 28mm up to 105mm, and nothing worked well, the 77 happened to work the least badly. I'm surprised you were able to get anything to work. I found that there were varying degrees of what I found to be unacceptable cropping no matter what I did.

Does greater sensor "real estate" equate to better image quality?
Posted By Wheatfield

Mike, you are asking two different questions and then conflating one with the other.

Question one is does more real estate give a better image?
Time and again by many, many photographers using all brands, the answer has been shown to be yes. Were it not the case, manufacturers wouldn't be bothering to make large sensor cameras, since they cost more to build, cost more for the end user to purchase, and therefore sell in smaller numbers.
Expensive products represent a much riskier proposition than cheaper ones from a marketing and sales point of view. If there wasn't an advantage to making and buying them, they would be neither made nor bought.

Question two seems to be will this better quality matter? The answer to this is, of course, not necessarily. My rather extreme examples were designed to show this. If your display medium is designed to compromise quality, them the quality available is wasted. or at least compromised.
Regarding the (now deleted) post about the Ferrari stuck in traffic not having the potential to go 200KPH, just because the car is in a traffic jam doesn't remove the potential to drive it fast, it just means that it's a little slower to get to the race track today.
I know people who have very nice stoves that never have never cooked something in the oven. Using the Ferrari argument, it's obvious that the oven can't be used to cook a roast, since there has never been a roast in the house to cook. Not using the oven does not remove the potential for the oven to be used. Take a brisket out of the smoker at the stall, wrap it in foil and put it in the oven for another few hours and voila: you have the base for a delicious meal. And yes, I am making the assumption that the oven actually works.

I think if you break it down to the two questions you should have asked rather than trying to conflate two different things into one question, you would be closer to getting a clean answer.
Regarding my choice of truck, my last one was supposedly able to tow 4500kg, but always felt like it was being pushed around by the trailer. Moving to the much higher capacity, and much heavier vehicle, I'm not being pushed around by the trailer any more. I'm not using the truck to it's full capabilities, but that isn't the point. The capacity is still there, and I feel much more comfortable under utilizing it than coming close to utilizing the full capabilities of the much lighter vehicle.

What you seem to be saying is that if a person doesn't take advantage of the higher level of quality available to them, then that extra quality doesn't exist.
Respectfully, I disagree.
My truck will tow close to 9000 kg of trailer. That doesn't change because I only tow one that weights 3000kg.
The capacity is still there.
Likewise, a person who uses his K1 to take pictures of his cats, runs them through a filter on Instagram and pretends he is clever and creative may be wasting the potential quality available to him, but this does not negate that the potential is there.

Presuming that basic kit includes the stuff needed to keep the camera running and able to save images (batteries and cards) and isn't considered accessories, then for me it's polarizing and neutral density filters.

Best LTD Prime Lens To Stitch

For APS-C, I would think the 35/2.8 LTD would be the way to go, if you want higher resolution, the the DA* 50/1.4 or the70/2.4 LTD would be my choice.

It's one of the recurring themes. If it hasn't happened already, someone will surely point out that a Honda Civic is better than a Ferrari Tributo because the Honda holds more bags of groceries.
The point is, if you put enough caveats onto the final use, you can prove that a Kodak DCS100 is the best camera out there. You just have to be willing to use a broken cell phone as the display device, and voila, the 30 year old digital is as good as the latest and greatest from anyone.

Sometimes the structure is too far gone to repair. The one I was quoting on was an old lath & plaster finished house that still had knob & tube wiring, lead pipes and a fair amount of asbestos. The roof had been leaking for years and there were significant mold issues. Also one wall of the basement had collapsed entirely (it wasn't a supporting wall or else the building would have fallen, and one of the supporting walls was not far behind).
There was so much remedial work required that it was cheaper and safer to bring a backhoe and some dump trucks in, knock it down, haul it away and start again than it was to put the amount of labour required into fixing it. If the building had been in better shape, it could have been lifted and a new basement put under it, but the building was too far gone.

Then more real estate = a better image.





QuoteQuote:

The sensor is key, clearly. What if the optical instruments are outstanding on both, but the full frame sensor is an older 12MP model, whilst the APS-C sensor is five years newer and 24MP, with greater resolving capability, dynamic range and high ISO performance? That's unfair, of course - as extreme as your lens example - but I'm using it to emphasise the need to qualify the statement that "greater sensor real estate equates to better image quality". What about two sensors from the same era... Even if technical data suggest the larger sensor is better than the smaller, does it translate to appreciably better image quality? Possibly (probably, perhaps)... but under what scenarios is that benefit realised, and to what extent? Will the "average" user (if there is such a thing) realise those benefits? Will the person asking "will I get better image quality from a K-1 than a KP" realise those benefits?



It doesn't matter if the benefits are realized or not. Taken to the lowest common denominator,m there isn't much difference between a cell phone and a full frame or larger DSLR. The larger format still gives a superior result. It's there if you care to look.






QuoteQuote:

Since I started the thread, that person is me... and I'd hope you know I'm always honest :D I'm happy to start off with format being the only significant difference in the comparison. But we should recognise that opinions and advice given to others in these (and other) forums regarding larger vs smaller sensor formats is usually related to practical usage - for instance, where folks are deciding which camera and lens to buy... and then, factors other than sensor format really do matter, and blanket statements become riskier. If a person is going to give an honest recommendation on comparative image quality between sensor formats when asked for advice, these factors have to be considered... IMHO.



If the only significant difference is the sensor size, then the larger sensor wins out every single time.

Yes.
This has been shown to be true time and again, though it is possible to skew results in favour of the smaller format by deliberately sabotaging the quality from the larger format. For example, a really good lens on a small format will give better results than a piece of garbage lens with separated elements will give on a larger format.

If a person is going to have an honest discussion regarding this, it has to be a given that the format is the only significant difference in the comparison.

Hopefully your house is worth more than the 25 dollars that a Kitstar 135/2.8 is worth.

A number of yeas ago I was called in to quote on a heavily damaged house. The repair quotes (I was one of four companies that were asked to submit) were well above what the structure was actually worth.
It ended up being a tear down.

Things need to be kept in perspective.

To add to this, there is nothing better for an inexperienced photographer than to work with an experienced model. You will be working with someone who already knows how to look good for the camera.
I'm my first post I mentioned working with the same person over and over. This gives both people experience at what they do, and over time the easy rapport that is built by working together will make for better pictures as well.
I've been in both situations. An upright Prima Donna is not my first choice for someone to work with. They can exude a special sort of toxicity that can make you want to stick a pen in your eye.

The other advice I have is don't be a jerk. The model has skin in the game as well. The ones I shot tended to have a lot of skin in the game.
A model will make or break a photo shoot. Don't be an ass about anything. If you are doing time for print, then deliver pictures on time. If you are paying money, then pay fairly and quickly.
If the model wants a few files for his or her portfolio, hand them over with rights to do what they want.
If you read the forums on Model Mayhem, a recurring theme is "I shot a model and now she's put my pictures on Instagram without my permission, what should I do?".
Generally the egos come out in full force, and the advice is issue takedown notices, send her a ridiculously high invoice and that sort of thing.
One would think these people poop roses.

I take a pretty relaxed approach. I write both my name and the model's name into the exif data and share the copyright. I've always felt this is most fair, especially in a TFP agreement.
The alternative is to be a jerk and watch how long it takes before no one will work with you.

1) Take a course in lighting.
2) If you havenít already, take a course in human relations.
3) Look through some of the portfolios on Model Mayhem or similar website.
4) I found that working with one model pretty much exclusively for a couple of years really helped.

2021 can’t come too soon.

---------- Post added Aug 6th, 2019 at 07:05 AM ----------



The shrinkage of the entry and mid level camera markets is, in part, being caused by the huge improvements in cell phone cameras.
That horse has left the barn, and no one is going to rope it back into it’s stall. This same effect is happening in other market areas, but cameras seem to be the most obvious victim of disruptive products coming on the market.
Like it or not, segments of the market are moving upscale to give them separation from segments that are elbowing in on their traditional turf.
People who are closing their wallets because they want the cheap and cheerful stuff that they have always been able to buy are going to be holding their breath until well after they turn blue.

Yeah, we only pay for the stuff from concept to design to manufacture to shipping, middlemen, final retailer, tariffs, duties, and taxes, as well as profit margins for everyone who putís their hands on it.
Iím not sure what part of the supply chain you think is free, or why you think companies donít pass the cost of duties, tariffs and taxes along to the end user along with every other cost that goes into the manufacture.
Are you saying that you, as an end user, is not paying out the cost of taxes and tariffs on products? If that is what you are saying, you have been woefully mislead.
