Does anyone have any recommendations? Thanks


Sigma 8-16mm. Much wider than Tokina, if you can live with f4-5.6

I recently purchased Ansel Adam's book, "The Negative" specifically to understand and learn to apply the zone system of exposure. I just reached the chapter on the Zone System and though I shoot digitally, I'm finding that this system is amazing and can definitely be an added bonus. I also recently purchased a top mint condition Hasselblad 500CM that I'm over the moon excited to start using; however, there are some things that I need to learn about film photography. I've become a student once again and it's truly exciting.

The Zone System works best with sheet film, where every exposure can be custom processed. Trying to do it with roll film ensures that compromises will have to be made, unless you have the same exposure objective with every frame on the roll.

Makes no sense. Why do they care if the jpgs started out as raw only capture? I can see why they don't want gigantic raw files, and certainly jpgs are all a news organization would need, but how the photographer took them originally is a moot point I would think.


They are trying to ensure minimum processing of images. For what they need the quality loss in jpgs doesn't matter, and it ensures consistency.

Enjoyed discussion of PRIME vs, ZOOM lenses. Now I would like to ask any one who used TELE EXTENDER supplemental lenses. For over 5 decades, 2X tele extender was very cheap alternative for getting your SLR
camera system, i.e. made a normal lens 50mm/f=1.4 to 100mm/f-2.8. The image quality in center was acceptable but edges are terrible. So, it was used for only portrait photography? Yes, it was very good special artistic tool.
Meanwhile, as optical design and production have been making great progress, I start using two tele extenders for my EF 70-200/2,8. They are small and light weight, 1.4X extender make my lens 105 to 300mm f=4.0. Then, the 2X piece making my relatively heavy big lens 140 to 400mm 5.6. Realized, sensor ISO can be good and much higher than film time, so I had better handling to shoot sport photography EF 300mm f=2.8. Since I borrowed such fast prime lens, I did not have time to make comparison. Is any one there shooting with modern improved tele extender's?

I have a 2x extender for my Sony 100-400 and it is absolutely brilliant, much better than my vintage teleconverter. That being said it cost a pretty penny...

But I am correct in thinking that there will always be a trade-off between IQ and detail when comparing pixel numbers and pixel size in any given sensor? I'm thinking that less pixels means larger pixels, which logically means more room for more detail?


Each pixel has a single luminance value and a single chrominance value. Other things being equal, the only advantage to larger photosites is better low light response. Things like color bit depth and dynamic range depend more on sensor design.

Two nights ago I did a gig at a Chamber of Commerce event at a very high end community center. I was hired by the chamber, as was a social media guy, and a video guy. There was also an independent person taking photos. What we all had in common (and this has never happened before!) was we were all using Sony equipment. Now I know this will ruffle the gentle feathers of so many on this blog, but the reality is that market share is everything, and I as a Sony shooter am even amazed at how much is changing in the professional sphere. Years ago it was rare to find a pro shooting Sony, and now it seems that we are the majority. For there to be four image makers at an event and all of them using Sony had me pretty shocked. People vote with their feet and their money, and the other brands have to be on notice to up their game.

In addition to having a good understanding of aperture, shutter speed, ISO, composition and "working the scene", a photographer has another secret...VOLUME. If you make enough photos of any subject, some of them will be good!


In the day, Nat Geo photographers could easily go through 100 rolls of film every day while on assignment.

Why is 50mm generally considered the transition point between what is considered wide angle and telephoto?
It seems that this would vary depending upon format and even to a greater extent the subjective opinion of someone.


Because the focal length is equal to the diagonal of the sensor. Of course it varies with sensor/film size

My understanding is that which mode you use should be based on shutter speed - at least between EFCS & mechanical. I don't think the issue is the same with the electronic shutter. However, unless you need blazing speed or no shutter noise at all, I don't use the electronic shutter since it only gives you a 12-bit sample, vs. 14-bit with the other shutter modes, which effects your image dynamic range - which is important to me. As with the other two, my understanding is that at slow shutter speed, up to maybe 1/250, you should use EFCS, because there is less mechanical vibration introduced that can effect the IQ, especially at the lower end, even with IS. However, at high speeds, you should use the mechanical shutter because the EFCS can spoil bokeh - not completely sure why but that's what I've read. I suspect that these differences are not huge in any regard, but if you're trying to maximize your IQ, that setup is what I've read. I use my R5 that way and have always been happy with the results.

What happens with EFC at high speeds is that the sensor does not have a chance to completely charge before the rear curtain cuts off the exposure, so the top of the frame becomes quite dark, and the bokeh "balls" all become dark at the top. I'm not sure about Canon readout speeds; if they are faster than the Sony, then this may not be a problem, or may only be a problem at the very highest shutter speeds.

I have not had any of those negative issues with the R7.
If I should in the future, I hope that I am smart enough to change to full mechanical shutter or electronic shutter as the particular situation would demand.
That, I believe, is why we have been given the 3 options.


Sometimes if you are shooting in an auto mode that allows changes in shutter speed, you don't notice the problem until the chance to redo the shot is lost. I have lost shots that way and so generally don't shoot EFC in bright situations at wider apertures.
