CCD vs CMOS Sensors - Which do you prefer for "Colors"?
Posted By Fenwoodian

.
I have a 10MP Pentax K10D digital camera with a CCD sensor. I also own some newer Pentax cameras with CMOS sensors.

To my eye, I see a subtle difference in the way CCD cameras render color as compared to the way CMOS cameras render color.

I know, that the sensor itself is not the difference maker, rather the CFA that sits on top of the sensor itself. So, let's not get into a technical discussion on that.

For those of you who shoot both CCD and CMOS cameras, do you too detect a difference in color? If so, how would you describe this difference, and which do you prefer CCD or CMOS colors?

Here's my latest Ebay flop. I'll bet that you've never heard of this one before.

I purchased a digital camera from a Japanese seller. He didn't mention in his ebay description that the camera menu was all in Japanese.

When I received the camera and found that the menu was in Japanese (which I don't read), I thought, OK, I'll just change the language in the menu to English. No such option with this camera.

I contacted the seller, who agreed to give me a partial refund of about 40% of the value of the camera. I decided to take the refund and keep the camera.

All's well that ends well. I spent an afternoon with an English version of the operating manual and "Google Translate". I will only be shooting RAW files and manual focus lenses, so many of the menu settings were not of concern to me. I was able to set up the camera to shoot RAW files, and it works great. I just hope that nothing happens in the field where I need to change a menu setting.

The advisory commercials, TV spots, posters and cards do little.

I've observed in my area (Wisconsin, USA) that there is very little adherence to social distancing, limiting the size of groups, non-essential business closure, or any of the other preventative measures that our governor has ordered and enacted into law.

There must be vigorous enforcement of these controls. Without penalties for violations, the number of deaths will continue to grow unchecked.

I'm all for martial law - enforcement at the point of a bayonet. That's the only thing that the masses of undisciplined young Americans will heed.

In a town near where I live, they had the first case of confirmed virus announced today. It was a 20-year old who returned from a spring break trip to the beaches of Florida. God only knows how many others in his community that he infected after returning home. Florida refused to clear their beaches during spring break these last few weeks, knowing full well that thousands of young adults would likely be exposed to this new virus.

With a November election coming up in the USA, I believe that most USA politicians are loath to take too strong a position on clamping down on unacceptable behavior for fear of loosing precious votes.

This is not a "political" post, as I'm lambasting all politicians in both parties here in the USA.

I'm not wishing for a new Pentax full frame, because the K-1 does everything that I need "for still photos".

Want better video? Get another camera brand that shoots in 4K.

A couple of days ago, Nikon announced that it's closing its' repair facilities world-wide because of the virus.

I don't know how Precision Camera is coping with the virus, but at the very least, if they are not closed I expect their repair capacity is greatly diminished for many reasons that I don't have time to review now.

Given the above, I am very glad that I currently own two Pentax K-1 bodies (and that I know how to do some rudimentary camera repairs). Should one of my K-1's go down, and repair not be available, I've got the second body that I can use if I'm unable to self-repair the defective unit.

On the APS-C front, I've got a K10D and 2 other similar CCD APS-C bodies (Sony A350, Fuji S3-Pro) and a few modern Fuji X APS-C bodies too, so I don't worry about backup with my APS-C bodies.


Do you have a back up body?

What will you do if your main body fails and you don't have a backup?

Is it time for you to think about buying a backup body?

OK, we've all heard a lot about "your experience" in this thread. To your eye, Pentax lenses trump Zeiss lenses. This, you admit, is based on small jpg images you've seen on the Internet that were shot by other photographers.

Can I take a moment to share my experience? It happens to be the direct opposite of yours. I've owned all but one (15mm) of the Zeiss Classic lenses, and four of the Milvus lenses. I've Leitax adapted and tested more Zeiss ZF lenses to K mount than anyone not named David Llado in Spain. Also, I've owned just about all of the better Pentax lenses (with only two or three exceptions). Overall, to my eye, the Zeiss lenses are better in overall rendering and sharpness - in fact, I currently own only one Pentax lens (a large telephoto) and most of my main lenses are Zeiss.

Overall, Zeiss lenses cost more than Pentax lenses and are of newer designs. Newer and more expensive lenses are expected to be better than older and cheaper lenses, right?

The Pentax K10D has 10.2MP APS-C CCD sensor. I just purchased a 14MP CCD sensor Sony A350 camera and a couple of A mount lenses (unfortunately there is no K to A adapter available that focuses at infinity).

As far as I know, the 14MP CCD sensor that is in the Sony A350 is the most MP of any CCD sensor produced for a digital camera.

I'll be sure to post some comparative photos between these two excellent CCD cameras. From what I've seen on the Internet, the colors/rendering of both cameras are very similar, just the Sony has more resolution (and a tilty LCD screen and live view). They both have IBIS though.

I have a 90mm Leica lens (I thinks it's an APO) that (with some custom adapting on the lens mount) I hope to use on both bodies in this test. Should be interesting...

Just got back from a two week vacation in sunny Arizona, USA. The only camera I took was my K10D. Below are a few photos I took with it.

10MP is not too little resolution for me because I use Topaz Gigapixel for up-sizing when needed.

I am finding that I prefer the colors that I'm getting out of the K10D's CCD sensor over the colors that I get out of my Pentax K-1, K-5, or K-3 CMOS sensors.

On my Arizona trip I only took one lens - an adapted Nikkor 50mm f/1.2 AIS lens. In the near future I'll be testing some of my adapted Leica lenses on the K10D. I suspect the K10D and Leica lenses will be a "marriage made in color heaven".

Item for Sale
Zacuto Pro Viewfinder Kit - Customized for K-1 or K-1ii - "Nail Manual Focus"

Asking Price
85.00 USD

Item Location
wisconsin (United States)

Item Description
.

For the last two years I've focused 100% of my K-1 photos by using a Zacuto viewfinder attached to the back of my Pentax K-1 camera. In my opinion, it's the best way to consistently nail critical focus on those narrow DOF shots (especially for older shooters like me).
















You Tube




There are various sizes and types of Zacuto viewfinders, and I've owned all of them. I've finally settled on this size/model that's the perfect match for the Pentax K-1 camera. This one covers the entire K-1 LCD screen, with no part of the screen blocked out (like some do).

Also, unlike many stock Zacuto baseplates, with this particular Zacuto baseplate is the only one that can be installed on a K-1 (or K-1ii) and not block the battery door.

This viewfinder kit has already been custom fitted to my Pentax K-1 camera. All you have to do is attach it to your K-1, adjust the focusing wheel to fit your particular visual acuity, and you're ready to consistently nail focus with your manual focus lenses.

This used Zacuto viewfinder has pristine glass and a smooth operating focusing adjustment wheel. Overall it's in near mint condition, with some of the components being brand new.

Please note that this viewfinder will NOT fit onto a K-1 camera if the camera has a vertical grip on it.

You will receive an excellent, used Zacuto viewfinder, and all of the extras that are show in the first photo (of course the K-1 camera shown in the photos is not included).

This viewfinder comes with 4 extender frames. If you find that the focusing wheel on this finder is not sufficient to compensate for your poor vision, you can insert one or more of these extender frames until you achieve perfect focus.

I will consider shipping outside of the USA for an extra charge...

Paul, the review you have linked to is a post that I made about my feelings about a copy of the original MOG trioplan. That lens is about 50 years old, was very well designed and manufactured, and produces excellent soap bubble bokeh.

This thread is about a new version of this lens made by a different company. The new company has no relationship to the original MOG, they only have adopted their name. The new lens is TOTAL GARBAGE. I am in the business of buying defective lenses and repairing them. This new MOG lens fell apart while I was gently using it to take photos of Christmas tree lights. The damage was so severe that the lens could not be repaired. I took it apart and have never seen any lens so cheaply designed and manufactured.

The new lens is $999. I'll make you a deal... You send me $500, and I'll happily send you the worthless pieces from my modern MOG lens that fell apart in my hands (I kept the pieces as the company that made it would NOT either repair it, refund my money, or even answer my many emails).

You can still find good used copies of the vintage original authentic MOG lenses on Ebay. I'd suggest you buy one of the original old versions used instead of one of these new versions.

An "other" that didn't appear as an option is "to further differentiate my images from the hoards of unwashed masses who are using smart phone cameras".

I have a Panasonic micro 4/3rds camera and some nice Panny lenses. Frankly, I can't tell much difference between the photos that I take with this small sensor camera and the images my son's make with their iPhone 11's. However, the images I make with my fabulous full-frame Pentax K-1 are far better than what my son's can produce with their smart phones.

I have some of the latest, high resolution full frame bodies. However, I've found a new niche that I'm currently exploring - old CCD sensor cameras.

CCD sensors were ahead of their time. Even by today's standards, they have extremely low noise and exceptional colors. I've recently puchased 15 year old Fuji, Nikon and Pentax CCD digital cameras. The Pentax one is the K10D with 10MP. You can find them very cheaply here on the forum. I'm glad that I bought it for a number of reasons.

K-70 Terrible video results.

I used to own the K-70. It does take good 1080p video if you know what you are doing. Read and re-read the manual. Then play and experiment with its' video settings. In time, you too will get good 1080p video out of it.

Don't know what your background is, or what your expectations are. If you are expecting 4K video quality out of any Pentax digital camera, you aren't going to get it and you'll be disappointed. However, as far as 1080p goes, it's certainly good enough for most amateur videographers.

Pentax K-1 vs Nikon D810 manual focusing test (K-1 wins)

Replies: 11

Yesterday, I was testing a couple of adapted Nikkor-O 55mm f/1.2 CRT macro/close-up lenses. These are old lenses that have no focusing capability. One focuses this lens with your feet (or more likely with a focusing rail).

Anyway, I tried this lens on my Pentax K-1 and on my Nikon D810 cameras. I nailed the focus on most of the images I took with the K-1 with focus peaking on; conversely, very few images taken with the D810 were in focus because the D810 does not have focus peaking.

For my style of photography, focus peaking is a necessary feature. I don't think I'll ever purchase another body without focus peaking.

I drank lots of coffee for a long time. Then a couple of years ago I had heart issues.

So, I substituted green tea for coffee because it has less caffine. Also, I stopped drinking caffinated soda pop.

Astro-Baby, nice post! I appreciate you sharing your experiences.

In the last couple of weeks, I've purchased 2 copies of one of my favorite bokeh lenses (Nikkor 50mm f/1.2). They were purchased for $100 and $150 USD. They were so cheap because of heavy infestation of fungus/rough-focusing/haze/etc. I did a CLA job on each one and now they're in excellent condition.

On the worst of the fungus encrusted elements, I didn't think that my standard treatment/removal regimen of hydrogen peroxide (3%) and naptha would do the job, so I experimented with three heavy duty chemicals: vinegar, "Lime Away", and "CLR". Well, these three heavy duty treatments did no better than my standard hydrogen peroxide and naptha treatment.

You Don't Need A Scanner When You Have A Pentax K-1

15-years ago I scanned most of my medium format slides on an expensive Heidelburg flatbed scanner. The scanner broke down and I never did get around to scanning my 35mm slides and print negatives.

A fews weeks ago I purchased and inexpensive Nikon ES-2 Film Digitizing Adapter. I finally got around to using it to scan my ancient 35mm slides and negatives.

I used the below Vivitar macro M42 lens on my K-1. I've tried many macro lenses, and in head to head tests, this lens was found to be the sharpest macro that I tested. In fact, when properly focused, I can see individual film grains in the slides. This lens has a 62mm filter thread, which is needed for the Nikon ES-2. You can probably use other macro lenses, but you would need an adapter if the front filter threads are not 62mm.

Taking photos of the slides was easy. However, it took a considerable amount of experimentation to nail the best settings for shooting the negatives.

Once I got the hang of it everything went pretty quickly, and the results were better than I had expected.

Below are the K-1 settings that I ended up using in case you are interested:

1. Slides - large jpg files, APS-C crop, natural color setting, ISO 1600, no IBIS, f/4.5 , 1/90th

2. Negatives - large jpg files, APS-C crop, digital filter set on "Invert Colors", flat color setting, no IBIS, ISO 1600, f/5.6 (not as flat as slides), 1/10th second

I'm not sure APS-C Pentax cameras have a digital filter setting that can be set to "Invert Colors". You need this setting in order to shoot the negatives.

Also, the young boys in the below photos are my sons - they're all in their 40's now.

The BEST lens to learn lens cleaning on...

Last night I inspected a Heilios 44K-4 58mm f/2 lens (in K mount) that I had and found lots of dust/haze inside. So I decided to take it apart and clean all of it's lens elements.

Over the years, I've done CLA jobs on dozens of lenses. I had never taken part one of these cheap Helios lenses before. But I found that this was by far the simplest and easiest lens to take apart of any lens I've ever worked on.

This would be a terrific lens for someone to work on who's wanting to learn the basics of taking a lens apart and cleaning one.

The only tool needed is a spanner wrench. By the way, I used 99% isopropyl alcohol to clean the glass lens elements.

First, I'd like to say that I highly value the exisiing data base of lens reviews that are archived here on Pentax Forums!

Here the 4-step process that I use when referencing these reviews:

1. I look at the overall lens score.
2. I look at the photos and the individual ratings given on bokeh (the most important lens feature for my type of photography).
3. I read the detailed reviews only on those members who have made the highest number of post here on Pentax Forums.
4. I re-read and "study" any lens review posted by PF members who either practice my type of photography, and/or I highly regard. For example, the PF members who best meets those two criterion for me are teiki arii and les3547.
