Prakticar 28-70mm f/3.5-4.8 Test shots

Praktica 28-70mm f/3.5-4.8 Multi coded zoom lens in m42 mount

This lens was tucked away in an old camera bag not used for 25+ years. When I bought my K100D about 8 months ago, I did not realize the pracktica lens share the same m42 mount. This lens was one of the three M42 lens in my old camera bag that are of least interest to me as I find the focusing ring too short and very slippery for manual focusing work. I was trying it out today not expecting much from it.

I used my bower M42 to K mount adapter and it is one of the lens that I have not used for a long while until today

bower m42 adapter:

my pentax lens:
Hin's Tech Corner... .../10/inexpensive-gear-with-pentax.html

The manual focus lens come out unexpectedly sharp and it is my first time shooting flying birds with a manual focus lens. Please allow me to show bigger size for few test snapshots that I like:

#1


#2


#3


#4


#5


and I use my DA 50-200 on some flying birds before and even with AF.C, I am never close for a keeper. Some strange logic applies here and I really like the short and slippery focusing ring on this Praktica zoom 28-70 in m42 mount.

All shots are hand held in Manual and stop down metering with adjustment to double the speed as I find the metering is off 1+ stop in my K100D. C&C are welcome especially for shooting in manual focus mode and stop down metering. I find all of my M42 lens to be underexposed by a full stop to +1.7 Ev compensation in Av mode.

Thanks,
Hin

OMG All of those where taken with a 28-70?!?... (wonders why he wasted so much time and $$ on 200mm telephotos).

I should take my short telephotos out more often.

I contradict myself sometime in looking for the next gear and not knowing I already have more gear than my needs and there is no need to find another gear. It is odd that the obsession in looking for another lens always run in my head. It is quite true, I don't need the next lens until I can figure out how best to use my existing lens. Every lens not used is an EXPENSIVE lens. And every lens has its different character and a great story for its prime use. I should write a software to ban myself from ebay and marketplace in all forums that I lurk in buy & sell.

Thanks,
Hin

love the pictures!
I've been building up a collection of M lenses as I've started to go the manual focus route. A lot more work, but man... those photos (plus my experience with autofocus) has me convinced that manual focus and old school lenses rock!

Pete,

Thanks for the comments. I just happen to be very close to the birds. And I think if I bring in a DA 50-200, the autofocus may have yielded a different shooting, maybe better or worse and I can't even tell. There is one time I was out with DA 50-200 set on AF.C in a hiking trail and I shot few active birds flying/dancing around in mating season around spring/summer time and none of shots come out satisfied. I might be just too far from the birds and they moved in a unpredicted fashion that I couldn't pan/track their movement. With the seagulls, at least I can pan some of their movements.

Warmest,
Hin

I am doing the same thing in building a bunch of inexpensive M42 lens so that when I am out, I can shoot all in M42 lens. I am currently staffed with Super Takumar 35mm f/3.5, Pentacon 50mm f/1.8, Prakticar 28-70mm Macro f/3.5-4.8 and Schneider 135mm f/3.5. And I am in the process in getting a 20mm f/3.8 and probably a longer prime or a longer zoom. It is difficult to find zoom in M42. If you have recommendation for something similar to DA 50-200, please advice me.

And here is a quoted post that I have in another thread to show my Praktica MTL5 film camera and M42 lens pictures:

QuoteOriginally posted by hinman Quote
I manage to get some shots of my 1st film camera -- Praktica MTL5
along with my Prakticar 28-70 zoom f/3.5-4.8. I used my K100D with
Pentacon 50mm f/1.8 to make it a complete shoot on M42 lens shooting
M42 lens -- all in hand-held snapshots with manual focusing and stop
down metering. First 5 shot with Pentacon 50mm f/1.8 in iso400
ranging from f/1.8 and f/2.8 to upper f/5.6. I shot this indoor
around 5:00pm.

#1
Praktica MTL5 + Prakticar 28-70 f/3.5-4.8 MC zoom


#2
f/3.5-4.8 not sharp picture but it is listed on the front


#3
love this shot for the contrasty feel


#4
my favorite today with Pentagon 50mm f/1.8 in probably f/1.8 to f/2.8
and
I don't remember my f/setting


#5
serial #


#6
Pentacon 50mm f/1.8
and I use my Prakticar 28-70 to shoot this in iso800 on f/3.5


#7
Pentacon 50mm f/1.8 has closest distance listed as 0.33m


#8
Pentacon 50mm f/1.8 open wide


#9
SuperTakumar 35mm f/3.5


#10
SuperTakumar 35mm f/3.4
love the small size and short neck, the focusing ring is the best
that I have used in manual focusing, it is as good as the Pentacon
50mm f/1.8, if not better.


Please don't go shop crazy for these lens as the Prakitcar 28-70 is
really hard in focusing with a short focusing ring. I am dumb
founded today in using it on shooting the Pentacon 50mm f/1.8 &
SuperTak 35mm f/3.5

All editing in post processing are done with Picasa minor tunning on
'I am feeling lucky', 'shadow', 'highlight' and light tunning
