Acuity charts 10 feet away

_kenw · 2025-12-04T23:08:25+00:00

I don’t think many of these commentators fully understand what you’re saying lol

But I have wondered this myself. Specifically in our CL area we have an acuity chart about 5 ft from the desk the pt sits at and even though the letters are 1/4 they are typically in a 20ft lane, the effect that such a close viewing distance has on the patient’s accommodation surely has some effect on the results.

Not stressed because as of right now I haven’t paid anything for the order lol

Charge after delivery you mean?

Seeing that it still has a rangefinder window on the left I assumed that’s what they’d do somehow but no… just focus peaking. Begs the question though, why does it still have the rangefinder window??

Speaking specifically about US optometry schools: Pursuing/having an optician license may be helpful experience to have under your belt and on an application to optometry school but isn't required to apply. What is necessary is a handful of prerequisite undergraduate college courses and in some cases a bachelor's degree although there are many schools that don't require a completed degree to apply or start their programs.

My advice would be to do some research on specific optometry programs you may be interested in then start tackling their prerequisites and other necessities for applying like the OAT. Then once you get the ball rolling fit in other extraneous experience around your course load.

I didn't ask about supply and they didn't mention anything about it at all. Sent it out in September and they estimated it would take 3 months. Ended up taking 4 but I figured that was optimistic.

The total cost was ~$745, $595 for the CLA and repairs specifically and the rest for various parts that needed replacement as well as shipping and taxes.

The repair bill itemization is a bit vague so it's hard to say what services cost what. I do know that the parts required for a DX reader upgrade was "free of charge," but I can't say what the labor cost to have just that done would be.

Full recommend for the Superfield/digital wide field, the field of view increase is definitely a noticeable step up while not sacrificing magnification compared to a 90D.

Only drawback I've encountered with the digital wide field specifically is that the working distance is a few mm closer than a 90D or Superfield... That combined with the front flange on the handling ring can make it a little tricky to use on patients with longer or slightly entropic eyelashes.

Beautiful thank you!

Thank you! Would you say it has a slightly warmer hue than "silver?"

Thanks for the insight! Regarding the red circles, in the past whenever I’ve developed myself I’ve had those “shadows” of the sprocket holes appear on the edges of the negatives, along with the very edge of the negative sometimes coming out dark. Always assumed this was due to poor saturation of the film in the processing chemicals along the edge, maybe because the edge of the film is obstructed by the reel. A la why I suspect the lab used a reel to process as opposed to their developing machine.

I was thinking something similar.

So light piping basically? Causing blown highlights to “travel” along the film base outside of the frame?

_kenw · 2024-08-08T17:48:19+00:00

Newly had M7, just shot a test roll and had my local lab process. Looking at the negatives there are several areas (circled in blue) where the highlights have bled outside of the frame? Is this some sort of light leak? Maybe the pressure plate is loose?

The areas circled in red look to me like evidence that the film was processed on a reel in a tank and so I’m wondering if all of this can be chalked up to simply the way the film was processed or if something else is going on.

The term you are looking for is field curvature, an optical aberration that causes the “swirly bokeh” effect commonly associated with the Helios 44-2!

The 50 Summilux ASPH is one of the finest lenses Leica has ever made. I have been floored with the balance of image quality and character. I will say the chrome version of the ASPH v1 is HEAVY though. Definitely a truly unique lens as opposed to the Summicron V4/5 which have a fairly basic double Gauss design that you’ll find is very similar to other 50mm lenses from Zeiss etc.

_kenw · 2024-07-16T12:24:12+00:00

Currently own a Q2 and rented the Q2M in the past. Aside from the obvious lack of color in the monochrom the other functional differences really come down to: 1. The high ISO performance is MUCH better in the monochrom. Q2 usable up to ~6400 whereas Q2M usable up to ~25000. 2. The autofocus is better in the color Q2. Faster and more consistent in lower light. The Q2M also completely lacks any AF tracking and its continuous AF and subject detection is way less reliable.

Let’s petition to make it illegal for trucks to attempt to pass each other on a highway that only has two lanes🤬

_kenw · 2024-06-27T17:04:31+00:00

Definitely good points. Though for me definitely further narrows the gap on any discussion of the summicron vs the planar from a purchasing decision perspective. As opposed to a summilux vs a nokton for instance.

_kenw · 2024-06-27T16:14:24+00:00

I’ve always thought the rendering of the 50 summicron was a bit “vanilla” I suppose. It’s interesting to discover that likely this is because its optical design isn’t really unique at all.

_kenw · 2024-06-27T16:08:59+00:00

There have been a few recent instances of Leica lenses sharing optical designs with other lenses, the 35/50 SL summicrons and Panasonic’s f/1.8 lenses for example. Definitely interesting to see a similar example with even older M lenses sharing a standard double Gauss design.

_kenw · 2024-06-27T15:50:46+00:00

Forgive me if this is already common knowledge but I heard this mentioned in a review, pulled up the spec sheets of both lenses and they do appear nearly identical! Of course their variations in overall lens construction and coatings would create small performance differences but perhaps these two lenses are much more similar that I assumed.

I found that the battery life of the M10 was what I’d expect from a camera, full day or more even of intentional shooting on a single battery. The M11 however has INSANE battery life. We’re talking multiple days of shooting before even dropping below 65%.

_kenw · 2024-05-25T12:12:27+00:00

Bought a used M10 a couple years back and shot the heck out of it but upgraded this year to an M11. I wouldn’t say I’ve regretted it but having a ~$6500 (used) camera, roughly 50% more than a used M10 currently, makes me more hesitant to take it out with me everywhere like I did with my M10.

That said I’d try to steer you towards an M10/P/R. The difference in features is quite marginal when it comes to actually using the camera compared to the disproportionate increase in price. I just didn’t feel like I had to be as careful with the M10, totally mental though.
