Canon Xti Repair – Part 3

admin — Sat, 21 Jan 2012 04:39:23 +0000

At last, Canon Xti donor number two. So I ended up replacing the entire mirror box and shutter assembly along with few other stuff attached around it which is pretty much everything. And the auto focus works beautifully. I can finally attach my Canon EF lenses!

Konica AR Mount & Nikon F Mount

admin — Thu, 05 Jan 2012 04:58:33 +0000

Here is the detailed look at both mounts; the Nikon F and the Konica AR. Bayonets on these are almost identical. Both have three tabs on the flange which are positioned almost exactly like the other. As a result, the AR-mount lens fits comfortably inside the Nikon F-mount. Once the flange sits nicely inside the camera mount, you need to turn the Konica AR lens in the opposite direction of how you’d normally mount a F-mount lens because of the way stoppers are situated.

The center top of the AR lens even ends up roughly in the center which is nice. You’re not going to hear the final ‘click’ as you mount. You somehow need to know instinctively when to stop turning. I stop as soon as I feel a hint of resistance. That’s when the top of the lens sits roughly in the center and the fit is firm enough to operate the lens and the camera. You DO NOT want to force rotate it more than you need to. You don’t want to find out what happens then.

And here it is on the Nikon D90. Of course, everything is manual and there is no focus to infinity. Also, unfortunately for the D90, there is no metering. But just look at that fit! And the Konica Hexanon is one darn good lens. Takes beautiful pictures and super crisp.

*Please note: if you are attempting this fit, do it at your own risk. This particular combination has caused no damage to my Nikon but I’m not making any guarantees.

Samsung NX200

admin — Mon, 19 Sep 2011 16:16:36 +0000

Samsung has made quite an impression with the NX100 Mirrorless System Camera last year. The competition in the Mirrorless Camera market is fierce. To combat the likes of Sony NEX-7, Samsung just introduced the NX200. The spec looks very promising.

Sensor: APS-C CMOS (15.7 x 23.5mm)
Resolution: 20.3MP (there’s a slight concern for noise at this level for sensor of this size)
ISO: 100-12800
Max. Shutter Speed: 1/4000
Continuous Shooting: 7 fps

Although Samsung claims autofocus speed of 0.1 second – which is quite fast even for dedicated DSLR – I doubt the NX200 will reliably perform at that speed in real world situations. But I don’t care. I want one.
The NX200 is quite possibly the most desirable Mirrorless System Camera on the market right now.

UPDATE (Sept. 21, 2011): Nikon introduces mirrorless!
