Full frame vs half frame

When I desired to move up from 35mm film to Medium Format, the first camera I bought was the twin lens 6x6 Yashicamat. It was a significant jump from 35mm. And yet I later realized that the twin lens system without interchangable lenses was the basic amateur system of its day.

On the other hand, digital 24x36 sensors can produce images close to the quality of professional Medium Format film. I still have my Mamiya RZ67. One of these days I want to do some comparison shots against the K-1. The advantage of the digital "FF" is that there is greater depth of field at a given aperture, field of view and subject distance. Not to mention the size and convenience.

DA 16-45 on the K-1?
Posted By DSLRnovice

A 24-75 or 24-128 would be handy, but with film I found the 28-100 zoom very useful. I don't mind changing lenses, and I really don't need a 12-24 full frame lens at the moment. The DA 16-45 covers the full frame from 20-45. I realize that it might not be the best option, hence my original question. What I need to find is a subject that would suit the 20-28 range to try it out, since I am covered after that with the 28-105.

Did some playing around with the 16-45 on the K-1. I might at least keep it for home movies, for the zoom and wide angle features. It is usable around 20mm on. For still landscape photos on the K-1, I find that infinity focus is best. The curvature of field helps the near things and the outer edges to be sharper at f8 and beyond. I have yet to find how much acceptable enlargement I can get with this technique.

On the K-20 the 16-45 covered many of my landscape needs. For the K-1 I have the DFA 28-105 which is good also. I picked up the Sigma Super Wide II 24mm, and have been thinking about something wider. I have not thought much about the 16-45 for full frame, but have found that I can get down to 20mm without significant vignetting at moderate apertures.

The color and contrast might make the 16-45, as well as the zoom capabilities worthwhile compared to older lenses like the A20. Is anyone regularly using this lens for the K-1? Newer choices seem to be out of my price range for now.

From digital to film

This might sound odd to some, but I am really missing my color darkroom. But I love the convenience of digital DSLRs. There are many labs that will scan film so corrections and manipulations can be done in software, but none that I know that can print digital to film with high resolution. The world of digital printing is frustrating and expensive. But I can easily make beautiful 30"x 40" prints in my darkroom from 6x7 negs and slides.

The K-1 should compete with the RZ67, in quality, but in convenience it blows away the RZ. To get a digital image on MF film without loss of quality would require an amazing film printer.

Carbon Fiber Tripods and shutter shock
Posted By DSLRnovice

Mirror up or 2 second delay are a given when there is time and on a tripod. LV and PS add even more time to the process and battery drain, hence the concern for a tripod that can reduce shutter shock if possible.

So I will rephrase my question. If using MU or 2 second delay, will a carbon fiber tripod dampen shutter shock better than aluminum of similar design and height?

This has also got me to thinking. Maybe it would be worth testing the difference between 2 second timer and MU for 5 or more seconds on a tripod.

Carbon Fiber Tripods and shutter shock

The Bogen 3001 with Medium Format film (Mamiya RZ67) was no problem. With mirror up and the leaf shutter in the lens there was virtually no camera induced vibration at any shutter speed. The amount of sharpness loss with the K-1 can be seen even with the tripod at its lowest leg extension from about 1/60 to 1/180 if I remember correctly, depending on the lens. This was using resolution charts. It may not be too evident in real world shooting.

The Bogen is a fine tripod which I have had for about 30 years. Once one of the metal clamps cracked and the company sent me a replacement without hesitation. It is the right height and light enough as well. Not the most fun dragging around when hiking though. It would be nice to find something a little lighter.

The cost of CF seems extreme for the small benefit, and if the lower cost versions are worse than aluminum, I will not be in a hurry to get one.

As for LV and PS I use them both. I get the idea of sandbags. Since I already have the weight of the camera bag to deal with, I have tried to find a way to fasten the strap of the bag to the tripod head, but it hasn't helped.

Carbon Fiber is said to dampen vibration better than aluminum tripods. My question is will it help reduce shutter shock on the K-1. Has anyone tested this theory?
My Bogen 3001 has served me well with Medium Format film, but I am thinking an equivalent CF tripod might help reduce the weight and get sharper images too. Only I want to be sure that the extra cost will be worth it.

Yes I know about LV ES and avoiding the shutter speeds that cause the most problems. It is not always convenient to use the work arounds.

It makes sense to me to compare unprocessed images. However, those from the older lenses can be improved in processing as well. Unless there are correction profiles for the newer lenses that are more effective.

Since the A20 is supposed to have the same optics as the FA20, I was wondering about the the distortion issue mentioned concerning the FA. Did you do correct any distortion in the images you posted from the A20?

Thanks for posting these. From what I can tell, the difference between the FA20 and the M20 is not as significant as I would have expected from the various comments in the forum. If there are quality differences that are not reflected as much in this test but might be important, have you noticed any?

Those images from the M20/4 look very nice. I do not normally take the 16-45/4 with me since getting the K-1. It takes up so much space. But I have been thinking that I need to use it at 20-24mm just to see how that FL works for me. Then I can decide whether or not to look for the FA20. The M20 would be great if I could be found at a more reasonable price.

The DA16-45 in FF does vignette at 20mm at most apertures, but the color and flair resistance has always been good.

I was wondering if the DA16-45 might come out similar or better than the M20. While the color and contrast is really terrific, the edge and corners can go soft in FF probably due to field curvature. The real disadvantage in FF is the size for using only the 20-24mm FL. (My DFA 28-105 performs well at 28MM) There is something very appealing to the size of the M20 that would make it worth the trade offs.

If I find one locally that allows a testing period, I would be willing to check it out. The A20 does not seem such a good value since the FA20 is not going for much more.

To round out my lens selection for the K-1, I would like a wider lens. I already have the DA 16-45, which is usable to about 20mm in FF without vignetting. I also have a Sigma A24/2.8 Superwide II manual focus. I am not expecting to use it enough to spend $500 for the FA20, at this time. But I am not sure if the M20 will offer better IQ than the DA16-45.

My use is for landscape and I need decent edge sharpness. Any recommendations for the best bang for buck wide angle of any era?

Epson 3880 head striking paper

It definitely is not the paper. When changing to letter size I forgot to check the platen gap, and now I can see the pizza wheel marks that are cutting through the paper as the front of the head assembly moves across the paper. For some reason the paper feeding mechanism is too close to the head unless I increase the platen gap to "wider." The lines are about 1 1/2" apart, from the top of the page to the bottom. I could not see the pattern before as I was testing on smaller paper.

No. The paper is not curled. All the different papers I used before are now having the same problem, unless I set the platen gap to "wider." The sound is loud and it is like something is about to break! The scratches are 2-3 parallel rows running from the top to the bottom of the print

Thanks. I did see that very video. I have done that before with an older printer that was clogged, but with Windex. I did the same thing today with the 3880 using Windex. It did need it except the heads were not clogged. There was no change, only this time I set the default menu in the software to use the wider setting. When I used the printers panel it would have to be reset every time it is turned back on. Prints come out fine with the setting on "wider." I just wonder if there is something mechanically wrong.

Thanks for responding. Earlier this year for some unknown reason the printer was making loud noises while printing on glossy paper. After some research I tried setting the platen gap on the printer to "wide" and the noise ceased. The heat was hitting the paper and actually scratching it. Today I had to set it to the widest setting for glossy paper. Plain paper was fine. I have found nothing in the manual for using a cleaning page. It would be good to find that as an option to tinkering with paper towels and Windex cleaner.

As I previously learned, changing the platen gap on the printer to wide has eliminated the head striking the paper on both plain and glossy paper for some time.

Since I had the matte black ink loaded, I printed a run of black text on plain paper before returning the gloss black. However, now the gap has to be set to widest for Epson Premium Glossy Photo Paper to stop the noise. I made a call and found that the Epson repair center in my area charges a minimum of $100US for the first hour and every hour after that plus parts.

So I am wondering, Is there a chance that a DIY cleaning of the underside of the head could help? I am referring to putting a paper towel under the head and adding Windex, as I have done with my 1270.

Also, am I causing problems sending copy paper through it now and then? Since I don't make many prints, I thought that would be a good way to keep the heads from clogging, and at the same time make use of the matte cartridge.

Any help will be greatly appreciated. If there is a mechanical problem, I am willing to send it in for repair. But I am also okay with leaving the platen gap to widest as long as things don't get worse.

I'm quite insufficient for my K-1..... and I know it!

After 2 years, I admit that I don't have many images that look significantly better than with my K20D. I have printed 13"x 19" with both cameras, and they both look good. The big adjustment was in the DoF, which works both ways. I can get great shallow DoF with the K-1 but the K20D spoiled me in the area of wide angle photos. Now I have to remember to stop down more often on landscape photos.

The big improvement was in quality high ISO with the K-1. OTOH the K-1 requires higher sensitivity for stopping down to get the required DoF. I am not complaining. I am coming from the big and heavy Mamiya RZ 67! The K-1 gives me the confidence that fine details that are important will not be lost - if I do my part right. When shooting landscapes on 35mm film, I knew I was limited by the format. Not so with the K-1.

I almost forgot. The K20D overexposed with most of my older lenses. The K-1 is better and allows me to use my older lenses and to get good deals on nice used lenses.

Shake Reduction with K-1

From what you wrote I am assuming that the 3 sec delay is using the self timer. That seems to be the only way to lock up the mirror and close the aperture before the exposure. It is only suppose to do this with the 2 second delay and not the 12 second delay, or MLU. Before your post, I did not realize that MLU was different than the timer.

If I am reading this right, how do you force SR while using the timer?

Use of filters and their need and affects on modern DSLRs

When scenery is wet the reflections can be eliminated with a polarizer in many cases to make the colors deeper. In my opinion using a tripod with slow shutter speeds is not that inconvenient. And a polarizer is usually enough to get slower shutter speeds for waterfalls, if you like that effect. Don't know if I have ever used ND filters or needed them.

It is good to know that software can accomplish the same thing, but not everyone wants to learn all the tricks.
