560TX is a very fast trigger, I always get even faster speeds than the official sync speed of the camera. About the 602... they must be good.

I must make some, but overall the Pancolar is not worse than Micro Nikkor for macro. The Nikkor has difractions problems after F8.0, Pancolar starts to get difraction from F16 so I like it for more magnification.
The nikkor is used without modifications on body and macro tubes which are pentax :).
It is awesome lens and at 4.0-5.6 the sharpness is so much that I can't describe it. If I make bigger magnifications with macro reel - that's the lens for shooting with focus stack. It is just sharper than anything else.

Yes it is not that safe and secure mounting, but it is enough to take photos. And you have infinity... Actually that's how I decided to leave pentax, I have tried some nikkors comparing them with pentax lenses and now I am migrating :).
Pre AI models are perfect for pentax - they mount much more securely. AIs must be modified a little if you want more secure mounting.
Lenses that I have used on my pentax:
Nikkor P 50 1.4
AF-S Nikkor 35mm and 50mm 1.8G
Micro Nikkor 55 AIS 2.8 and pre-AI 3.5

You don't need adapter to mount nikon lens to pentax body! It fits almost perfectly :). The working distance of nikon is higher than pentax so you just need to mount the lens. All the lenses will work as MF lenses and the ones with aperture ring will be more usefull, the others will need something to stuck the aperture at wide open and that's how you will use it. I have Nikkor 35 1.8 and micro nikkor 55 2.8 and used them on K200 and K30.

Zeiss Pancolar 50 1.8 or Pentax-M 50 1.7?
Posted By simbon4o

Build quality - The pentax M 50 1.7 is much better build than the east german pancolar!

Sharpness
Optical performance wide open - Both perform nicely, but the Pancolar is more soft in corners and the pentax gets sharp in corners faster.
Optical performance closed down - Here the Pancolar wins for me, the Pentax is sharp as the Zeiss until F8.0, after that the Pancolar stays sharp and the pentax gets soft. Pancolar is sharp enough even at F16.

Flare resistance - Pentax is much better here - the SMC coating is very strong in this lens and it is dificult to get flare from it. The Zeiss is MC or Zebra version(single coated) both are wih coating only on front and rear element and it is not the strongest one.

Bokeh - The Pancolar has unique swirly bokeh(MC version) like biotars and their copy version from the russians. The Pentax is more normal here but nice on night scenes. The aperture is 6 bladed for both but the shape of the blades is better on the Zeiss.

About macro - Pancolar has better rendering and the performance closed down gets points here.


PS about sharpness and bokeh - you can search for the KMZ Zenitar 50 1.7 too - it is sharper than M 50 1.7, CZJ Pancolar 50 1.8 MC, SMC Takumar 50 1.4 with smoother bokeh. It is my sharpest 50mm if I don't count the Micro Nikkor which is crazy sharp!

First - which pancolar?(single coated/MC) Because they are different.
Second - All Pancolars are different from M 50 1.7, for me it is all about character and the task you are going to use it.

I use CS6 and there is an option to create tweens between frames which is mixed frames, than I use not fast transition between frames and I think that's all.

Manual 28mm comparison - M, K & Vivitar

Those 3.5 28mm pentaxes are so soft in corners... why everybody says they are sharp. Yes colors are great, aberations are well controlled to almost none, but in corners they are soft even at F8.0, I have tested two copies since now and both are soft in corners, only F11 solves that problem. My M 28 2.8 II is sharper at all apertures excluding F16 and F22.
The previous test that I have posted was on K200D, now on K30... 28 3.5 is veery soft in corners compared to 2.8 II version.

Anybody with A 50 1.2 and K30? I have a problem.

All K30 and K-01 cameras not only mine have this problem, when automatic lens(A, F, FA, DA) is attached they close the aperture in LV during focusing. If the lens is set manually to exact aperture by aperture ring - it works like K/M lens in LV and the aperture stays opened.



That's too harsh, you can only remove the aperture lever who hits the mirror of canon FF cameras and works for the auto aperture on pentax cameras - much more easy and reversible.

I saw the problem(a colleague in the bg Pentax forum told me to look there)! The A pin on the lens does not hide when I set the lens to A and that's what is making the camera crazy. I hope that soon I will be able to repair it.

Still that closing down the aperture in A mode is stupid pentax decision and I hope they will correct this nonsense in future.

Actually the K-01 and K30 are the same :) from inside. So for me there is no surprise, but the problems is real and using ND or anything else doesn't help the aperture stays closed down. I don't think this is a saving the matrix procedure, it is more like a bug that stays 4 versions of the firmware. Peaking is useless if the aperture is closed down and at longer distances when the lens can't separate the background good enough so I'm shooting through the viewfinder for now.
I hope that soon I'm going to be able to buy Sony NEX` because this DSLR thing is very unpractical and annoying.

When I use LV the aperture closes to 5.6-8.0 and focus is impossible. With the FA 50 1.4 I solve the problem by turning the aperture ring to 1.4 and shoot with it like it is K/M lens, here this doesn't work. Is it possible that it is a bug with this lens?

And when Pentax will see this stupid mistake in K30's LV and I will have useful camera for manual focusing with old lenses?

I shoot on 3fps many frames and than chose those who can be stiched. In CS5 and CS6 Photoshop you have timeline and it can animate frame animation. That's it I save them as gif files.

I can't agree with the battery thing! The K30 has the worst battery life from all of it's competitors. About 400-470 shots max is not enough. The other thing is that the battery itself is very slow for recharging... I have never seen that bad Li-ion performance before in any camera. If I want to use the camera seriously I must use AA batteries who make the camera a little heavier and less comfortable. About the other stuff... yes K30 can do everything that K5 can.


About movie performance - there is no pentax model to this moment who is good for movies. The quality of the movie is not good compared to the other brands and the controls are poor... every Sony NEX camera from the last models can shoot movie much better WITH PEEKING without any modifications. So... maybe in the future Pentax will make this better.

Honestly ... K30 is almost the same as K5 - for the price difference you can buy lenses which will improve you photos much more than buying K5/K5II/...
