I have the Tamron 17-50mm and I am very happy with it. Only drawback with the K-5 is that the lens is not WR like the body, but you can't beat the price for the quality of glass. I would love to have a copy of the Pentax 15mm Limited, but I just can't justify that expense to myself.

My major problems with Adobe customer service
Posted By jon.partsch

Hello Friends,

If anyone can help me by providing some advice about how to resolve my problem, detailed in my latest email to Adobe customer service, included below. I have already spoken with B&H's customer service and they told me that I need to resolve the issue with Adobe, but I have had no assistance from Adobe at all. They have promised multiple times to follow up by phone or email, but have not.

Thanks for your suggestions!


It has now been over a week since I sent you the email message included below this one. I have received no assistance with my problems registering my software and requesting a complimentary post-announce upgrade to Lightroom 4.0.

The copy of Lightroom 3.2 that I have been trying to register was purchased new and unopened from B&H photo and video of New York as a full retail version of the software. I have spoken to B&H's customer service department, and they told me that they received the software directly from Adobe as a retail product, yet I have been told by Adobe customer service that the software (serial number [REDACTED]) is already registered to another person! I have been promised multiple times (over the phone, over web chat and over email) that this problem would be investigated by Adobe customer service, but no one has contacted me to resolve the issue. I first reported this problem to Adobe customer service almost three weeks ago.

To summarize my problem, I have attempted to register my retail copy of Lightroom 3.2, purchased as a new full retail product from an approved Adobe software reseller (B&H photo and video). Though I can view the serial number as registered under my Adobe account, I am told by adobe customer service that the software serial number is already registered to another person. I have been trying to register my legitimate, legal copy of Lightroom 3.2 and request a complimentary post-announce upgrade to Lightroom 4.0, but this has failed as the information submitted to Adobe keeps disappearing from the Adobe online portal. My invoice is attached to this email. This is the seventh time I have attempted to submit this proof of purchase to Adobe, but I have received no assistance yet.

Why the D-800(E) is not worth jumping-ship for

Your point is well taken. I shoot wildlife in the field so the K-5 is a much better (potential) tool for me, but I think that in can be stated objectively that the K-5 is a much more versatile tool than the D-800 (on paper).

36 MP is at the border of what I would consider reasonable vs. excessive. I think 4 fps (6 fps in DX "crop") mode is just too short to "capture a moment", even if you are doing documentary-style wedding photography, for example - especially if you want to do HRD or exposure bracketing or something.

Yes, this is exciting news, but if Nikon can do it, Pentax/Ricoh can do it better! Here's why I don't find the D-800 or D-800E compelling

1. 36 MP is too much! Too much storage space needed, too much processing power needed in post, too much work for the photographer! 24 MP is the upper end of what I consider reasonable. The sensor out-resolves most lenses - especially along the margins of the frame, where the FX format sensor has it's only advantage over APS format.

2. Slow full-format maximum framerate of 4 fps. This is just sad, and makes this camera crap for sports or wildlife photography.

3. 0.7x magnification viewfinder is too small for an FX format camera! Pentax should make one with 0.9x at least!

4. no in-body stabilization! Pentax will include this!

5. Pentax has glass that will match better (edge/corner sharpness) with a ultra-high resolution full-frame sensor in the future.

6. A Pentax offering will doubtless offer better build quality with better weather-sealing than a Nikon.

7. Test results are not in yet - we have yet to see if this sensor can beat even the K-5 for low-light noise and dynamic range.

The one feature of the D-800E that I do find compelling is the lack of the AA filter. That is a great option. I think Pentax can and should offer this option on a cheaper, faster, better-built 24 MP full-frame camera.

What do you think?

I am so excited about this announcement! I may be tempted to buy it with adapters before it comes out in k-mount. I need Minolta MF mount adapter too! This could very well exceed my dreams of a Pentax MILC/EVIL camera and keep me from buying into the Sony NEX system. I hope the K-mount is announced soon!!!!

I can't wait to see how this sensor tests! I am interested in the lack of an AA filter, as it would allow more control of detail if one is willing to do some PP.

Thanks for the suggestion - this looks like a great product, but way above my current budget as I am trying to save up for the K-5

Call me old-fashioned, but I haven't met a tripod yet that I'd be willing to spread my legs for on the first shoot ;)

Yes! That's exactly why I am looking for a lighter tripod! I only take the monopod with me on trips anymore because the old tripods are so cumbersome in comparison. I am looking for something similarly light and portable that will provide a stable platform for longer focal lengths or longer exposures than the monopod.

Thank you all for your input. I couldn't find a product more compelling to me than what I listed above, so I pulled the trigger last night on the purchase. PF will be getting its cut of my B&H purchase :)

looking for 300mm lens opinion

Hello Folks,

I currently use a minty Tamron Adaptall-2 SP 300mm f/2.8 LD IF (360B) which produces stunning results, even matched with the 2x converter (01F). My passion is wildlife photography - especially birds (which are often small and far away). I am considering selling this lens to finance the purchase of a Pentax SMCP-DA* 300mm f/4 ED (IF) SDM.

Is this a good idea?
Will I be sorry if I do this?

Tamron pros:
ability to use a good TC

Pentax pros:
lighter weight

Please help me decide! Thanks so much!

Best Low ISO Pentax DSLR?
Posted By jon.partsch
Replies: 30

This is pretty much what I assumed, and I would love to shoot with a K10 (I have a K110 now and am planning to get the K5 by the end of the year). It seems to me that the K10 would be a great body for studio work where you have control over the light, allowing you to shoot at ISO 100 or 200 all the time, and the K5 would be the ideal body for outdoors/available light sports and wildlife photography. It seems like the best all-around dream kit would include both the K10 and K5 bodies, but if you are only going to be a one-body photographer, it's probably best to stick with a newer model.

What does the rest of the community think?

Hello Friends,

I am trying to shed kit weight and I am thinking about getting this combo:

Giottos MTL 9251B 3-Section Aluminum Tripod Legs - Supports 11 lbs (5kg)

and this

Gitzo GH1780 Center Magnesium Ballhead - Supports 22 lbs (10kg)

This should add up to 3.81 pounds (1.74 kg). Does this seem like a good choice for the price. The current $80 Gitzo rebate brings the total price to about $220 US. I am more concerned with light weight than I am with compactness. I will want this to be able to easily support a K5 with the DA* 300mm f/4 attached for wildlife shooting. Do you think there are any better options at approximately this price and weight.

Thanks for your input!

FA 50mm f1.4 and F 50mm f1.7 conundrum - which one should I keep?
Posted By jon.partsch
Replies: 25
Views: 6,327
No, I am pretty sure they are both double-gauss designs. The Tesar and Planar designs are old technology and not suitable for lenses with fast aperetures of this kind. The FA 50 f/1.4 is a seven elements in six groups design, and the F 50 f/1.7 is a six elements in five groups design. In contrast the Planar is a double-gauss design with six elements in six groups and the Tessar is four elements in three groups (tessar-type design).

Sigma AF 35-135/3.5-4.5 New old lens: any insight?

Okay, I got the lens, and I have tested it. Unfortunately, I got a bad copy that exhibits extreme softness on the left side of the frame until about f/8 at all focal lengths. Aside from that tragedy, I think this lens has potential with a better copy (I will be returning it). Here is my subjective and relative review of the lens other than the misalignment/softness issue:

Best feature - surprisingly sharp wide open in the center of the frame for a budget lens at all focal lengths.
Worst feature - build quality and long minimum focus distance - front element rotates for focus

At 135mm there is mild pincushion and some vignetting wide open. Vignetting and sharpness improve at f/5.6. f/8 seems to be the sweet spot at this focal length.

at 80mm performance is good - vignetting and distortions are minimal. the sweet spot is f/5.6 at this focal length. F/22 is very soft at this focal length - avoid.

at 35mm the lens exhibits moderate barrel distortion. sweet spot is at f/8 at this focal length. Resolution drops off fast after this and f/16 and f/22 are both pretty bad here.

minimum focus distance at all focal lengths is 1.8m (6 ft!). This pretty much sux, but there is a really pretty bad manual close focus feature at 135mm only that you can engage by pressing a small button near the front of the lens and rotating the front element manually to focus. As I said, the front element rotates for focus, which is also bad and made worse by the plastic ring that contains the front element - it feels loose and turns rough, like it is full of coarse sand, when manual focusing. All this poor design around the front element makes an otherwise solid-feeling lens containing a lot of metal construction seem cheap and delicate (maybe it is). In spite of all of this, auto-focusing seems reasonably fast and accurate.

I hope to get my hands on a better copy of this lens so I can evaluate it more fully.

Hi Ben. This photo is stunning. May I ask what lens you used and what you did in PP? The frame is soft and dreamy around the edges (assuming PP here) and the subject is nice and sharp and well set off from the background, which displays buttery-smooth bokeh. I am assuming you are using an FA Limited here. If so, I am jealous as I will probably never own one myself. I am a bit inspired though to load some NPS and shoot a roll with my Sekor C 80mm f/1.9 - another great portrait lens.
I'm sorry about the rough relationship you are having with Pentax. I wonder though, if they really are going to be discontinuing the FA Limited series outside of Japan, it seems their focus is shifting away from portrait/fashion (since these are the only serious lenses they have for those applications) and towards attracting more business among 1)Japanese, 2)young amateurs, 3)women, and 4)outdoor shooters. It's a shame if they don't want to court wedding/portrait/fashion photogs, but I hope you will still share your work with us, as well as your tips and comments.

A better translation from the press release and an elementary German speaker :)

Pentax K-5

The new top model in the Pentax DSLR series brings with it all the hallmarks of a high-quality digital SLR. An apparent feature of its lofty claims is the dust-and splash-proof magnesium alloy case. With an impressive 7 frames/sec, the K-5 meets the needs of sports and action photographers. The 16.3 Megapixel CMOS sensor records optional HDR images directly in the camera.

Best Pentax DSLR for low ISO IQ
Posted By jon.partsch
Replies: 23
Views: 5,256
Thank you all for your quick replies. You have confirmed much of what I already suspected.

Now, are we certain that they share the same sensor?

Yes, I agree with this. I have shot my K110D at 1600, and I was very pleased with the results. Though noisy, the pattern of the noise was not unpleasant for concert photography.

Yes, I am concerned about this, but I am waiting for the RAW tests to come out on the review websites.

I thought that PF had more to do with microlens design or reflection from the sensor.

I hope you are correct about this.

The K-x gets no love at low ISO; why? Doesn't this camera have much wider base ISO DR than the others mentioned? Doesn't this increase image quality?

Are we optimistic about the low ISO performance of the K-5 even though we suspect it contains a Sony CMOS sensor like the K-x?

This is my question: There has been a lot made recently of the high ISO performance of the Kx, Kr, and K-5. What about low ISO performance? What Pentax DSLRs have excelled in DR, resolution and detail at ISO 100, 200, and 400. What Pentax DSLRs are best for long exposures at low ISO? Please tell me about your favorites. I get the sense (from reading the forums) that the K200 and the K10 are near the top of the heap; why? Can you give examples of the low ISO IQ of your favorite camera vs. others?

Thanks, and I hope this discussion is informative to all!

Thank you, Michael, for your voice of calm and reason. I am really disappointed by all the venom and angst on the Forum in the last several days. Maybe you are correct that it has a lot to do with the economy. I can imagine that it is really stressful for some members to think that they might have to spend some serious money to invest in another system if Pentax doesn't give them what they need. I would say to all those members, please take a deep breath - we don't know for sure what the availability of lenses will be, and we don't know for sure the performance and final specifications of the K-5. It's not worth getting heated about until the "chips are down".

Pentax has to change direction to be successful and continue to live on. Maybe that means focusing on the Japan market or the Japan/Western Europe market for now. Maybe it means focusing on compacts and entry-level DSLRs. It's nothing personal against the pro and semi-pro shooters here, it's just business. There are savvy people working in business development and marketing at Pentax to be sure, but maybe "you" are not the customer they are interested in attracting right now. Please, lets not put down the Japanese, Pentax and it's employees, or each other. Civil and respectful criticism is okay.

What a wonderful picture, Michael. I have very much enjoyed your reflections on life in Japan, as an expatriate, in these forums, and I'm very sorry to hear about the difficulties with your business. I hope you are able to find that cheap film body you are looking for before you leave Tokyo.

Hmm, you should be able to find a genuine Tamron K-mount adapter pretty cheaply on ebay or in the used equipment listings at Adorama or B&H. That's what I would suggest you use. There are only three versions of Tamron Adaptall-2 adapter for Pentax: M42 ("Screw-Mount"), K-mount, and K/A-mount (with electrical contacts).

This is an interesting question I would also like a better answer to: Can the flash output of the pop-up not be dialed-down? It seems if this is the case, it might make more sense to use the kit lens or the Tamron 90mm for the shoot for the flash integration - maybe not the ideal lenses for this situation, but would simplify things and perhaps lead to less mistakes.

And Miss_Alexx, don't listen to these haters that tell you you can't do this with the equipment you have - you can! Use negative flash compensation and a diffuser for subtle front-fill lighting to add to as much ambient or lamp-light that you can get on the subject (sunny windows = ideal).

I hope you will share the results of this adventure with us here on the Forum.

Wow you guys - he didn't say he was jumping ship. I'm sure Ben will use the gear that best suits his needs. If the ergonomics and glass of Pentax are needed by Ben, he will use them, just not tout them to the masses. This is completely reasonable - a professional at his level needs to have a good relationship with his brand, and their dealers and representatives.

I smell envy, and it stinks.
