So, I'm supposed to send my camera to these people...? (Precision Camera)

I sent my K3 in for service last fall under warranty. My camera was back in a week just like new. Keep in mind most people who actually take the time to write a review are generally very passionate about it. Most of those are complainers who simply can not be happy. Yes I am sure Precision has made their fair share of mistakes. That, however can probably be said of any service company.

Pentax DA* 60-250 vs. Tamron 70-200 on FF (K1) which one would you pick?

The K-1, DFA28-105, and DA*60-250 is my main travelling set up. The 28-105 is just an amazing lens for the price. I purchased my 60-250 used from B&H Photo over three years ago and have never had an issue. I keep the Tamron for indoor shoots or for sports. I am like the OP I guess. I know if I purchased the DFA 24-70 it would just sit home most of the time.

:o Yes I meant constant apeture. I should have waited till I finished my first cup of coffee :asleep:.



I did not know the 200 or 300 could be converted. That is good to know.

I have used over the years, A*, F*, and DA* lenses. I will say that there is difference from those and non star lenses. Build quality is higher and IQ is better. For me the biggest advantage is being able to shoot a lens wide open at its largest aperture. This of course means you need a good copy. Currently I have the 16-50, 50-135, 60-250, and the DA*55. All of the lenses are still running on their original SDM motors. The DA*55 however needs to woke up when put on the camera. Once it starts to autofocus it works fine. I compared my 16-50 against my 18-135 and the center sharpness of the 16-50 blew away the 18-135 at all comparable apetures and focal lengths. This of course was at the pixel level. My 60-250 is what I call my, can't fail lens. It probably my best all around lens.

Unfortunately the DA* line has suffered terribly from SDM issues. This is something that can never be ignored. Early on even I was unwilling to purchase one. I still feel the issue was never truely addressed. The newer motors do seem more reliable but the damage has already been done. The autofocus on all of my star lenses is far from stellar. The 50-135 is like focusing through molasses. However for what I do that is not an issue. It is one of the sharpest lenses I own.

Every lens you buy will be a comprise. Your have to decide if the comprise is worth it for you. If buy a new Star lens from a reputable seller these days you should be in good hands. If you buy one from some unknown Ebay seller good luck. Who knows how long it has been sitting on a shelf. As for used ones, just beware the motor could fail at anytime. If it is a 16-50 or 50-135 it can be converted to screwdrive. For all others you either replace the motor or focus manually.

*I stand corrected, it seems the DA*200 and DA*300 can be converted. That is good to know.

The DFA 150-450 is not a Star lens since it does not have a fixed constant:o aperture. All * lenses have fixedconstant:asleep: apertures.

I purchased mine used from B&H Photo about 2.5 years ago. So far no issues at all. Mine came in essentially mint condition. I would buy used but only with a return period. With any lens there can be issues which may make you decide not to keep it. I have the DA*55, DA*16-50, DA*50-135, and the DA*60-250. All lenses are still working on there original SDM motors. The DA*55 does need to be focused a few times but then it works just fine.

The DFA 28-105 is one of the few lenses that just continues to impress me. It always goes with me with the K-1. That and a DA*200 would about be your best FF lightweight kit in my opinion.

I agree on the prime verses zooms issue. When I started in photography primes were king but those days have long been gone. For me the DA*60-250 is the lens that best fits this bill. The DFA 70-200 is just too heavy for me to carry around.

Awhile ago another Forum member asked about size difference in lenses. I posted these photos of some various lenses. The Tamron 70-200 and 60-250 are second and third from the right. Fully extended the 60-250 is slightly longer than the Tamron. Overall the 60-250 is lighter and more compact. It fits better in a camera bag. However when I really need the extra stop, and there are times I do, the Tamron goes. If size and weight are a major concern than the 60-250 is definitely the way to go.

From left to right;
Sigma 50-500 OS HSM, this lens has become to heavy to carry.
Tokina 400mm 5.6, lightweight and compact but best IQ is at f11.
HD DA55-300 WR, This and the 18-135 where my all around kit.
DA*60-250, my K-1 all around kit and the DFA 28-105.
Tamron 70-200, my sports, action, and close up lens.
DA 18-55, sits in a drawer and never comes out.

I have both lenses, the K-1, and the K3. They are different lenses. My 60-250 is modified and I designed the replacement baffle used in the Homepage article. The 60-250 is just a joy to use. Smaller, more compact, and of course weather sealed. The Tamron is about the most compact 70-200 f2.8 lens there is. The Tamron also has a closer MFD than the 60-250, although the 60-250 is not terrible either. For low light shooting or action shots, I go for the Tamron. I think for portraits I would favor the Tamron as well. For a two lens kit I grab the DFA 28-105 and the 60-250. All weather sealed and ready to go. If I had to pick between the two it would be a very hard choice indeed. I think it would end up being the Tamron for the extra stop and closer MFD. I feel everyone should have a 70-200 f2.8 lens if possible.

DA 10-17 FE usage tips/quirks/limitations

The DA10-17 is a lens full of comprises. It is not a lens to use every day. This a lens to have fun with. There are many negatives to the 10-17. It fringes like crazy in high contrast situations, even stopped down. The corners are never sharp. It needs to be stopped down to get decent IQ. I shoot mine regularly at f11. On the plus side, fringing is easy to remove in post. Newer DSLR'S can handle higher ISO's so stopping down is not so much an issue. The lens is so small it easily fits in the camera bag. From 13-17mm the images easily defish if composed correctly.

My advice is:
Stop down to at least f8, preferably f11.
Pay attention to composition, fisheyes and UWA's are unforgiving for poor composition.
Use a tripod if you can, especially for landscapes. It really does help.
When shooting below 13mm, use Live View and manual focus for best results.
Stop the lens down, yes I typed it twice. You really need to do it.

I have the DA*55, FA 50 macro, and the DA 50 1.8. The DA*55 is in a league of its own compared to the other lenses. I use it on my K-1 more than the K3. The FA 50 macro is probably one of the sharpest lenses I own.

The DA*55 has its issues of course. Autofocus is slow and frustrating at times. Mine needs the typical DA* waking up when mounted to the camera. This lens has a high SDM failure rate and can not be converted to screwdrive. However I would be more than happy to use this as a manual focus lens. It is that good. From f1.4 to f2.0 it can be a bit soft and exhibit some CA. After f2.2 this is no longer an issue. On mine the IQ peaks around f5.6-6.3. The DA*55 can focus quite close which is definitely a plus for me.

The FA 50 macro is sharp right from f2.8. It will exhibit some CA but can be corrected. The lens is heavy for a 50mm lens. The focus throw is around 180 degrees since it is a macro. A focus limiter would be a help. The DFA version does have quick-shift capability. The DFA, FA, and F versions all share the same optics.

If I could only one it would be the DA*55. There is just something specail about the images it can produce. The bokeh is very pleasing and not too busy. The rounded apeture blades help. The color rendering is that specail Pentax pixy dust.

If I did not have the DA*55 I would definitely consider this new lens. Looking at the images from the only DFA* lens, the 70-200, I can not wait to see images from the new 50. Who knows maybe I will end up selling the DA*55.

Thoughts on the 60-250mm for the K-1?

I pretty much use the 60-250 on the K-1. Without modifying the baffle it vignettes pretty heavy at f4 and 250mm. Modifying the baffle essentially makes the vignetting equal to my Tamron 70-200 on the K-1. I designed a new baffle that I 3D printed in the lab where I work. It has been in my lens since last summer. The baffle used in the In Depth Review was my design. I uploaded the files to my Google Drive for anyone to try and use.

250mm f4 on the K-1.

I agree completely. I was just venting, sometimes you just need that. Everytime I think Pentax isn't meeting my needs I just look at what the other manufacturers have to offer. Essentially it is just lenses I would not buy or can not afford. My ASP-C lineup is covered from 8mm to 500mm. My K-1 is covered from 12mm to 500mm. I have absolutely no reason or desire to complain. I do know someday I will have that DFA*70-200 though.

Lately I have not been taking many photos due to health problems, so I have been venturing into other areas. Hopefully the new year will bring a change to that.

The DA 20-40 is not full frame and not a constant aperture which is how it remains small. I would love to see something like a DFA 20-40 limited. You can guarantee if is not a constant aperture people will complain. After getting the DFA 28-105 I do think I will worry about constant aperture zooms anymore. The Cannon 40mm f2.8 is a very small lens. My friend has one. However everyone seems to want f1.4 lenses. A lens at the aperture is not going to be small. Physics simply will not allow it.

Honestly I do not see the FA Limiteds ever being rereleased. Those are different lenses from a different time. Richoh will probably keep making some into the future as long as they sell. We are going to see new DFA and DFA* primes. These will not be the compact lenses of the past. Everyone wants silent focus and that comes at a price, increased size and weight. Eventually Richoh may release a new set of DFA Limited primes but they will not be the compact designs of the past. These, like the DA Limiteds, will be a new set of lenses with modern designs and coatings. When or if this day will ever come is anybody's guess.

Ugh, I don't understand the amount of negativity I have seen lately. It has driven me away from the forums. I keep coming back less and less. If I could buy a DFA*24-105 F4 lens for my K-1 it most likely would rarely come off. I have my DFA 28-105 which is just great. I do not know one professional photographer, and I know quite a few, who does not own a 70-200 f2.8 lens. I could not imagine shooting a wedding without one. The DFA*50 will definitely be a welcomed addition to the Pentax line up. I already have my DA*55 which I am quite happy with. The lens will be released when it is released. The DFA*85 is more appealing to me but I am sure it will be out of my price range so I will stick with my Rokinon 85 1.4. Pentax is such a small share of the market new items can only be released so fast. Release too many at once and you flood the market and do not recover profits fast enough. If you feel the need to always have the newest and "greastest" gear than switch brands and stop your whinning. Go pay twice the cost for your gear and let the rest of us enjoy taking photos with our outdated substandard gear. I know I certainly enjoy using all of mine.

This is going back a few years so I hope my memory does not fail me. If I remember correctly, the original ME Winder used 6 batteries and only was 1.5 frames per second. The ME II Winder was a bit smaller only using 4 batteries and had a faster frame rate of 2 frames per second. Neither of these were considered actual motor drives. The only motor drives I remember were the Motor Drive A and the Motor Drive for the LX. The LX and the MX both also had dedicated winders. I still have my MX Winder but the MX no longer works.

Pentax ME Super and Super A Questions

I don't think leaving the Motor drive in auto will matter. From memory I do know this.
1. Motor Drive A is 3.5 frames per second. Me Winder is 2 frames per second.
2. Motor Drive A has additional button for portrait shooting. I always found that very helpful.
3. Motor drive A will not rewind film. Me Winder does rewind film.
4. The battery pack on the Motor Drive A is removable allowing you have an extra on preloaded with fresh batteries. I had an extra battery pack for this.

Over the 20 years I used my Super Program I used the Motor Drive A almost exclusively. The Me Winder is smaller and does rewind the film but the Motor Drive is just more versatile.

Your can find an English copy of the manual for the Motor Drive A here --》https://www.manualslib.com/manual/499069/Pentax-Motor-Drive-A-System.html#manual
