dust or haze?

I've had an FA77 that had this much dust and a touch of haze too. It really didn't affect IQ and now I know I was being a fussy bugger by returning when I should have just kept it. I think its probably normal for the lens, having owned a few of these. I think two of them were cleaner while two were very similar. All returned awesome images.

Yes this is something that can be done, and might fix the issue if it was caused by a drop that pushed elements out of place. What I'm referring to is probably more to do with decentering that isn't sorted by a quick re-seating of elements. There doesn't seem to be a way to 'align' the elements other than their original seats yet some repair shops can somehow do it. Do they replace parts or have they got ways of checking and addressing the optical alignment?

It looks like dust from the images you've shared. For a better idea, get a torch and shine it through the lens from the rear. If it's haze then you'll see it clearly as a blue/grey foggy layer.

If the lens is delivering good images then there is no need to spend money on 'fixing' it.

What's wrong with my front element?

This isn't something that you can really get too wrong with a gentle hand. Use a rubber tool to unscrew the front and then you'll get an idea of whether the front element can be removed and cleaned. If it works, you've saved yourself the service cost. If not, then it's still fine.

In fact you could probably sell for 70-80% of the normal used value and buy a used replacement if you're really fussed about it.

I wanted to check with you - for most Pentax lenses I've ever disassembled, there doesn't seem to be any way of adjusting the alignment of lenses. How would a repair shop sort out a decentered element short of replacing bits?

Fully agree with this comment.

Almost certainly not separation. I think the elements in the front are accessible but not completely sure. The newer lenses have elements glued together (I think the rear ones for sure, maybe the front group too).

Pentax K-1 Mark ii user, feeling frustrated about being stuck with only the kit lens

I think you may have a poor example of the 28-105 because from many reports the only advantages the 24-70 has are the wide end of 24mm and the larger aperture at f/2.8. The 28-105 is only a kit lens by name. It's probably one of the best 'kit' zooms available for any system.

I use the Pentax 'Multi-Bag' (here) and can fit the 01, 02, 03, 06 and 08 lenses in there with a couple of spare batteries and a usb charger. It's a tight fit but it's possible!

Cameraville's comparison between DFA* 70-200 and Tamron 70-180

The DFA* is super sharp from wide open. Clearly the reviewer has an issue on his end.

And I'm surprised at his approach to this review. Normally he's kissing Pentax's tripod mount but this time it's the complete opposite. I sense he's also annoyed at the fact that he's gone through 4 copies.

This kind of attitude I really don't understand.

30 years ago you had Pentax cameras and lenses that could be used to create beautiful images.
20 years ago you had Pentax cameras and lenses that could be used to create beautiful images.
10 years ago you had Pentax cameras and lenses that could be used to create beautiful images.
Today you have Pentax cameras and lenses that could be used to create beautiful images, with further pro-grade equipment being released for the people that require the highest levels of image quality.


What changed?

I think you might have been mistaken. I wouldn't call the optical design "delibrately compromised", and neither do Pentax. They're very clear about the Limited range being about the joys of photography and the lenses produce images that are greatly pleasing to look at. There are no compromises on that objective.

As an example, I've used the Samyang 135/2 which is one of the sharpest lenses out there. It produces Zeiss levels of sharpness but is a very boring lens to use because of the clinical nature of the image. The DA15 is the polar opposite. The sharpness isn't there but somehow the image that you get is beautiful and punchy.

The D-FA 50 does a great job of being excellent at sharpness as well as character, but even then the images can be considered clinical.

So in terms of compromises, the only compromise you should be considering is the one on your pocket.

I'm very surprised at how poor the FA 150 seems to be at actually creating dreamy bokeh. It's very clinical in nature. I've got one but I'm just a collector, not much of a user so I haven't really worked with it too much.

What I find amazing is the 105/2.4 :)

I think a direct test should also include wide open results as that's where the appeal of the f/2.8s would show.

What I do to shoot dimmer areas is find a few key stars that indicate where I should be looking. Stellarium is a great resource for this. Live View is infinitely more useful than the viewfinder, and use manual focusing with the zoom function. Turn focus peaking off. Take a trial snap with ISO set to as high as you want (1/2 second exposures are fine) to see whether you've got the correct region in your image.

You're right about being able to turn off the NR in the settings. It's pretty much a forced dark frame.

What you should be aware of is how dark frames are affected by conditions such as ambient and sensor temperature. Make sure that your camera is at operating temperature before shooting your lights and maybe shoot some darks in any downtime you get. You might want to shoot some bias shots as well as flats, and again getting everything to the right temperature is key to avoid any influences of thermal expansion etc.

Play with the aperture ring, set it to A. And also manipulate the lens to see if it's an internal contact issue.

Using APS-C lenses with a FF sensor
Posted By HarisF1
Replies: 37

My point was more about someone transitioning to FF over time. There aren't many drawbacks. What you gain from using crop lenses is greater FoV and DoF from images. To get similar stuff on crop sensors would require faster lenses. It's really about getting a few extra percent detail here or there and ultimately it's not necessary to upgrade unless DoF is your goal.

Strong comment, easily disproven. Take any APS-C lens with a near full-frame circle and you get a greater field of view on the K-1. You may need to crop but you still get excellent results from existing equipment until the opportunity to upgrade appears.

Of course the objective should be to eventually get a complete full frame system.

All of your lenses apart from the 16-85 will have some use. The Sigma covers the full frame circle to a decent level when near the long end, and the other lenses are still more than useful on the K-1. You would only need to swap the 16-85 for a 28-105 for a similar price and your kit is pretty much good to go. The 55-300 might not be so hot on FF but it will still be more than usable with slight cropping.
