Fuji X100 Digital SOMETHING from Fujifilm

[ebino]

Some clarification on my ISO importance remark.


With digital by controlling the ISO one can control both aperture and shutter speed. Lets say you wish to shoot on the street. you set the camera at aperture priority, set the f stop at the sharpest sweet spot of the lens and set the ISO. As you move and face different lighting situations or action all you have to do is play with ISO and the shutter speed adjusts itself while the aperture is still at the sharp sweet spot.

With digital cameras its the ISO which determines the image quality and hence the most important factor, and thats the reason when you shoot digital you want to have full control and easy access to ISO setting... So X100 with an ISO button would have meant no need to visit the menu ever during shooting -at least in majority of cases.

for YOU.

which is cool. but not everybody shoots the same.

 

[ebino]

Thanks, I'd likely be less diplomatic. One would have thought that such an obvious truism would be, well, obvious. There are only two variables in determining exposure: the amount of light hitting the light recording surface (affected by shutter speed and lens aperture), and the sensitivity of that surface to light. It's not rocket science, people.

Actually there are three variables, the sensitivity of the surface, the amount of light and the period of time when that light is exposed to the surface.

i have found that Auto-ISO has improved my the quality of my pictures immensely

This is a big advantage for digital. Auto and/or variable ISO in cameras that have an acceptable working range from 100/200 to 1600 minimum. It improves pictures and makes manual control less necessary.

Variable ISO actually enhances - or frees you up considerably when you want to shoot manual using digital cameras with full manual control. You can set aperture and shutter where you want it and the ISO will change accordingly and in some cameras within a pre-set range. You couldn't for instance, shoot at 5.6/125 in lower lighting conditions if you were stuck with 200 speed film in you camera. With a film camera your usable aperture/shutter combinations are tightly constrained by a fixed film speed. This is not true with digital cameras with variable ISO. As you said, a Godsend.

Actually there are three variables, the sensitivity of the surface, the amount of light and the period of time when that light is exposed to the surface.

Actually... In his post, he assumes the amount of light is a product of the intensity of the light hitting the sensor, and length of exposure. Which is correct.

Your 'correction' would be correct if you substitute the word 'intensity' (or 'brightness' for 'amount'. Because the amount will vary with exposure.

IN an ideal world you should be able to program ISO like the Hexar does aperture and shutter in P mode. IE, if I can program so that when the aperture's fully open, and shutter needs to go slower than 1/15, then ISO can rise to 400, or whatever I've set.

I would say that having a "Auto ISO" limit you can set may already be in the X100. Why not. almost every D-Cam has such a control.
My G1 has it... I can set both low and high ends, if I need too. Like ISO 100-400, or ISO 250-640, and just us "A" or "S" mode... I'm sure Auto_ISO would working in program mode is useful. But, I use this in ISO option in "S" mode most. Let the camera pick the f/stop and ISO in those instances.

Nothing wrong with that, but how often do you need an exact combination of f/stop AND shutter speed?

That is an unhelpful reply, because it confuses two different quantities.

You are referring to luminous flux (the amount of light hitting the sensor per unit time).

The poster to whom you are replying was referring to total exposure (luminous flux integrated over the exposure time).

Both are valid things to measure. Both are valid to discuss.

You're doubtless right - but my point was that this needs to be in combination with similar program controls for f/stop and shutter speed.

What's good about the Hexar is that you can leave it as your favourite f-stop, but it will over-ride when necessary, ie when you're trying to shoot wide open in the sun-shone, when the shutter speed won't go over 1/250. It's incredibly versatile in practice.

When you're taking pictures. 'Exact'? You can argue. But I like as much control as possible.

Cheers,

I concur. I have almost completely fallen out of love with camera automation... except I would welcome auto ISO.

It has been 4 decades since I used the Hi-matic 7s.

I do recall the shutter "throw" being long, but then I bypassed that by learning to half-depress the shutter if I anticipated action...waste a frame often until I got the hang of it.

AA stuck in my mind and I had often wonder why others don't take a look.

That's Okay, I bought mine in 1969. I still have it and the instruction manual. Fresh in my Memory...

Now- on Manual Exposure, think we can program the firmware to give the EV readout on the screen and thenprogram it to show the EV value actually selected by the Shutter Speed and F-Stop? And make it show "AA" when on Program Mode. I'm thinking "RETRO-CAMERA Personality Firmware Loads". Kind of like custom ring-tones for phones. Just program the firmware to behave like your favorite Fixed-Lens RF.

Who has the SDK?

So, a dial or some kind external ISO/Auto ISO control?... Film cameras had a dial inside the shutter speed dial, just lift the outer dial and turn.... Ummm That sounds real good, And have the Auto (From ISO to ISO) control in the menu....

Fuji should have consulted RFF members before getting started on the X100 🙄 😛, with all these "Needs and Wants" we have....

Fuji...so far. 😀

Will one or the other make you not want the camera? It's probably pleather.

It is not a deal breaker for me. I do not care what the material is as long as it feels good in my hands and is durable.

I don't even care if the material feels good or is durable, if the camera meets my other requirements. I can always cover it in something else.

Hi Gang,
This is a great thread on a great forum.

Anyway, I've been trying to get the business case approved with my lovely financial controller for a Zeiss Ikon mit 35 f/2 lens for quite some time with no success. Now I find myself thinking that this little Fuji might just succeed where the Zeiss failed.

If the IQ of the X100 is at least as good as my Nikon D90 + 24mmF2D lens I'll be all over it, if my financial controller lets me. Fingers crossed it's not all hype......

Cheers

I found that a pit stop at Tiffany helps my business cases.
Might hurt your camera budget tho 😛

And, in some particular cases, for a long time 😀
