Improvement: Manual Focusing Screen
I went ahead and had a Katz-Eye™ manual focusing screen added to the α700
so I could make optimal use of my various TAMRON Adaptall 2 MF lenses (135 f/2.5; 200mm f/3.5; 70-200mm f/4; 200-500mm f/6.9)
That 135mm f/2.5 seems to be a super lens ... and I am interested to see how improved the quick focusing will be.
Unfortunately, the closest focus this particular lens can do is just under four feet, but it should make for a decent portrait lens though.
Anyway, the camera is on the return trip from Maine, where the Katz-Eye™ was installed. I am anxious to get it back and see the results. Allthough I could obtain a sharp enough focus after a few shots, with the DSLR, my eyes just don't have the twenty-year-old's acuity any more. Yes, you guys, we all get old. Just you wait ... you little whippersnappers! I am pretty certain this will tighten things up a bit ... and I'll be able to seriously use this older glass, which is still sharp as heck ... a bit more successfully.
Some manual operation required ...
Halleluiah, the α700 is back!
α700 Katz Eye™ installed:
Okay ... I did initially notice that focusing, with normal lighting, is tremendously improved. As I dimmed the lights, it got to be more difficult.
As I closed down the aperture, again, more difficult to focus. I found that focusing at the widest aperture and then immediately adjusting the aperture to what you want seems to solve that issue. Technique and procedure, that's all.
It definitely improves the performance of the AF lenses (135mm f/2.5, 200mm f/3.5, 70-200mm f/4.5, 500mm f/8 Reflex and 200-500mm f/6.9).
If the weather clears up, tomorrow ... I may just head for the lake (Lake Michigan) have a manual lens day ... just for the fun of it. See if I can improve my DRO experiences along the way, also.
Is it worth it? Hard to say, at this point ... but, it does speed up my manual focusing, enormously. That's definitely improved and worth something. I have five lenses that have suddenly improved in performance and usefullness.
Autofocus ... okay, here's a spot of trouble with α700. The α700 has three focusing modes: WIDE, SPOT & LOCAL (Camera defaults to WIDE, when in the AUTO). "Wide" and "Spot" seem to work fine ... "Local" control ... if you select anything other than center ... I think it's kind of lost, which effectively has killed it. Personally, I have never use "Local" ... so I don't suffer with its loss, but I am sure there are others, out there, who might resent losing it.
Anyway ... that's it for now
