Pentax 28mm shift lenses grossly overpriced.

It can make sense to buy a camera that works with the lens you want. The NIkon 28mm and 35mm PC lenses are inexpensive and then, for example, you can get a Nikon D700 (for $400) [still a superb dslr] or a Nikon film camera like the FM or FE [also great] for about $100. I have all of these in addition to my Pentax cameras. BTW the Nikkor 35mm f/2.8 PC lens is fast and small--just a bit narrow FOV depending what you want it for.

Although I never actually took a count, this is also my gut feeling about AA lithium (Energizer) vs rechargeable eneloop AAs. An order of magnitude difference.

If you go back and see my original post (above) w/ fish-eye hemi, I added the correction w/o the additional perspective adjustment in photoshop (for your camera not being level). The point is you don't lose any (or none I noticed) of the original image with this software.

I use it as a plug in for photoshop. For me (mostly) I use FE lenses for the very wide FOV and because after using fisheye hemi they have less distortion than a very wide rectilinear lens, particularly for vertical lines and people near the extreme edges, and you lose essentially none of the image, thus perfect for my theatre photography and landscapes. I actually have more FE lenses than any other category (5 of them).

If you have not seen what fisheye hemi software can do, I took the liberty of applying it to your image (and a minor perspective control).

I thought it would be interesting to show the Fish-eye hemi correction w/o the PC adjustments (the Perspective Control adjustment was done only because the camera was not level). I think you can see the fisheye hemi loses none of the original image, or any none that I noticed.

for my Theater Photography (when it comes back!)
2 Nikon D-700's, usually with 35mm and 50mm AF lenses (but choices of MF 16 mm FE to 200 mm)
2 Pentax K-5, usually with 16mm f/2.8 FE, 20-40mm Ltd, or (K) 135mm f/2.5

Everything else now is usually film--lots of choices--ranging from 35mm (FF), 35mm panorama, and 120 (6x6 mostly).

Vintage filters

Often the circular filter is then put in a square frame (as you have). Also circular filters may be inserted in the rear of the holder, such as the standard PL (not for example the yellow-blue PL)-, but these are in a much thicker sort of toothed circular holder. And, although none of the ones you show are it, there are Cokin A size--the smallest, and two I believe larger than the P size that you have.

Actually the circular one with the smaller OD may be a Cokin A size, to be inserted into the Cokin A size frame, and then inserted into the A size holder. I don't recognize it, but I only use/know the graduated NDs, PLs, and color conversion filters.

Landscape Tripod

I like the older Tiltall tripod--I have the star D version, the Marchioni version was the original (believe all were gold in color), the star D was about the same time and is the same except mine is black, then Leitz marketed it, and then/now is made in China and not the same quality.

Used likely $50-100 plus another $30-50 for QR.

Comes with three way head that nicely takes a circular QR clamp/plate-- (I like Sunwayfoto DDY-64iL).

Quite sturdy and robust but weighs about 6.5 lb. Even w/o extending the center post it comes to my eye level and I am 5 ft-11 in.
Not sure why you want ball head for panorama, I find it easier to get level with 3 way head. Anyway it comes w/ head and not easily removed.

I do think much of the automation gets in the way, but I guess you can turn it off, but knowing it is there is not the same thing.

The other thing is being limited--with the camera/lens, writing a musical, developing a theory w/o the higher level math, whatever--can force you to be creative, and that can be much better than what one could do w/o the limitations.

Best Pentax lenses for shooting black and white images?
Posted By dms
Replies: 10
Views: 849
I don't use B&W so this is not from my experience, but an uncoated or now more usually a single coated lens may be desired. I believe the original motivation was limited DR of film and printing medium, the flare reduces DR. For more modern materials a single coated lens does the same to a lesser extent and I think it is giving a "smoothness" [my word, I don't recall the exact phrasing].** You can still buy single coated new lenses by Voigtlander [Cosina], and the price as I recall is the same for SC or MC. You might look at cameraquest website.
_____
** Pschlute mentions higher contrast, w/ contrasty lens (e.g., MC), and I think it is likely reduced micro-contrast that gives what I said is "smoothness" but I am not sure. Chromatic aberration may be influenced by coatings (I don't know, but seems likely), and w/o MC that would blur the boundary between colors, causing the reduced local contrast.

If you have not looked at it, the Rick Housh list of nikon hoods is quite complete w/ hood dimensions.

Nikon Lens Hood Specifications - Rick Housh

Unfortunately looking at it (I only use it for shorter FL) most of the longer FL's are missing complete dimensions, but do have the applicable lens FL/aperture and filter size.

Another source of (NIKON) lens filter size and lens hood ID is following:

KX: Save RAW after taking photo

I have not used it, but (cursory look at manual) you can change to Raw before taking a shot by a single press of green button (if you have have set up: change green button function --> raw function button) but apparently not after acquiring image.
Sorry you already saw this, about green button function. I did try taking a jpeg and don't see an option to change to raw, only raw to jpeg.

Macro advice
Posted By dms
Replies: 15
Views: 867
I would suggest a zoom w/ macro capability. The ultimate image quality is in principal less, but the zoom ability allows you to adjust image magnification w/o moving the camera (w/o other equipment)--this is a huge benefit in the field. Something like the Adaptall-2 35-80mm SP (01A) lens. Just take care because lots of zooms say macro capability but in fact are terrible. You can add extension rings, or teleconverter to get more magnification (I think it is a toss up--unless you want more working distance--then the latter). This lens is excellent except it flares badly (light sources will doubly appear)** but not likely an issue for macro.

** For me for theatre work it is unusable.

Nice illustration how cropping can strongly impact the mood, even though there are no major elements to leave out or include, no strong diagonals to emphasize, etc.

I happen to prefer the vertical crop, but both are strong.

Seems like buying any camera based on other than your own or a trusted like minded friend's experience comes with greater risk than another GR. You like it and it gave 5 years use under trying conditions. I would think another GR is indicated. A new GR model also poses a risk, but maybe acceptable.

I don’ t usually print greater than 8”x12” but I did make some 24”x36” for theatre display, and I upscaled from 12mp to 48 mp with bicubic smoother in photoshop (CS2 or CS6). The photos were typical theatre plays and had detail/close ups of faces, etc. and to me they looked as good as the 8”x12”, but they likely would not have been tack sharp.

I suppose for large static scenes with tripod to remove motion blur, etc. there could be room for improvement in upscaling, but I also think, for most of us/most of the time, they are trying to create a need where one likely does not exist. Of course the same is true (for the same reasons) of huge sensor resolution.

I think it is roughly a "wash." if you down sample by factor of four it is like having twice the diameter as the individual pixel sensor. Whether it is a wash upscaling likely depends on the image and the importance of fine detail.

If you are considering the Nikonos, then I suggest the Nikonos III. Totally manual, but super fast to advance film, build is beautiful. And the 35mm amphibious lens is quite good--although it flares easily. I use a 58-49mm step down ring plus a filter ring w/ glass removed and mount the Takumar 28mm square hood, effective and hardly cuts into the huge viewfinder. This was often my Europe travel camera. Also was/is my canoe trip/foul weather camera. I also recently got the 80mm telephoto but cannot yet comment on it.

Thinking of reacquiring a K-x...

The k-x is a fine camera, and I believe the k-r is basically the same, except you can see the AF sensors, but it does not take AA batteries. For me AA lithium are great--they last forever, and if I need them for my GPS when backpacking I can take them from the camera. Suggest you get it thru KEH, B&H, etc. so you can check it out on receipt and return if need be w/o hassle. If t works it should last and serve you well, and you have not sunk a bunch of money into it.
I personally don't want the accelerator/too much messing w/ my file data, and given that--I happen to think there is virtually no difference in IQ between my K-5, K-x, K-S2 and Nikon D700. And I don't need more than 10mp. Of them I probably am least enamored w/ the K-S2.

BTW the K-10D (I have the identical body K-20D) is a much larger camera, and for me is much more dated--anyway it feels very large--and [the K-20D] is inferior to the K-x image wise. Cannot speak to the older sensor CMOS vs CCD.

I don't believe the k-x/k-r has the bad solenoid. The k-x with litium batteries lasts forever, and is quite light. I also think the images are good and 10 mp is usually plenty.
I used two k-x and two K-5 for theatre photography (which has been on hold for a year) for close to a decade, and consider them close in IQ. I only recently retired the two K-x's in favor of two D700s.

I also have a KS -2 and I think it and the k-x are comparable. Somehow I don't care for the feel of the KS-2, but the flip out screen is nice, but you are taking a risk ** with it and the solenoid issue. At the price of the K-x/K-r I would think it a good deal. I just started my niece (back onto digital) w/ a red K-x and FA 28-70mm f/4 lens.
_____
** But there is a risk w/ the K-x/K-r that the control dial may start to skip settings as you turn it. Just make sure it is OK when you get it and hope it does not happen later. Camera is still fine, just need to turn dial again to get the aperture or shutter speed you wanted.

if it is happy with energizer lithiums AA (my K-x is) they are quite light and essentially remove the need replace for quite some time.

But the grip makes it a larger camera and seems not needed, in the scenario.
