#62681 Your Best Photo, Week Ending 9 June 2019

Posted by ScottinPollock on 05 June 2019 - 11:03 AM

Fun and super intriguing abstract, ScottinPollock--existing light only, or did you modify somehow? Seems tricky! And I'm dying to know what your subject was--take a step back, and what do we have?


Hi Nicole...

Existing light from a nearby window, with my hands cupped around the object for the reflections. The object is an ittalia shot glass, taken from top down.

ScottinPollock, I think you're still using Nikon too, right? What do you both think? Good move? I should probably start a separate thread to ask this, eh? But I'm seriously considering making the jump


I still have most of my Nikon gear, but I just don't pick it up much any more. The things I like most about mirrorless are:
1.) Dead perfect auto-focus (for still subjects) every time, every lens, every focal length.

2.) Live exposure/histogram/zebra-ing. It simply makes getting perfect exposure on the first shot. And if I want to blow out some hilights for more shadow detail, I can see exactly where that will be.

3.) IBIS - Tripod? What tripod?

4.) Video is extraordinary, without limitations.

5.) I actually have a capable camera I can put in a coat pocket (depending on lens).

6.) Stellar WiFi - Can instantly copy in camera pics to my server (a Mac), Google Drive, or even YouTube (no mobile device needed).

7.) Mobile app that works everytime, and allows me to tether from phone or tablet, with control of all camera functions (including magnified manual focus with peaking).

The cons:
1.) Tracking focus in most models (other than the A9). X-T3 and other Sonys are good, but not D500 good. Fortunately I don't do BIF and comparable stuff so not an issue for me.

2.) Not great for landscapes and astro... less dynamic range and more noise in low light then FF Nikon, but I can stack. Still it is noticeable.

I went Panasonic because of their amazing DFD contrast focusing. And there is some pretty small, amazing glass for cheap. And while I readily admit a D810 is capable of 2 stops better image quality, the overall quality of image also depends on nailing exposure and focus (something that is an absolute no brainer on mirrorless). And I seem to be getting more "pop" for the kinds of things I do than from my DX Nikons... plus, it's just more fun to use... and did I mention I can carry it in a pocket (c;... without getting "that look" from phone photographers and other standers by.

So yeah, it is hard for me to believe that any experienced photographer would not be excited about many of the new freedoms and features of mirrorless, especially if they're looking for a smaller kit. Definitely go with X-T3 over X-T2 as there have been massive improvements in auto focus and video.

I like how this one turned out... despite the damn dust.

#62536 D3500 Display not working

Posted by ScottinPollock on 29 May 2019 - 11:48 AM

Dunno. Just a thought.


Unfortunately, the D3xxx bodies have incredibly limited settings displayed in the viewfinder and settable without screen diving. Mode, shutter speed, and aperture are about it. I think you can assign ISO to the one customizable function button, but you'd need access to the menus to do it (if not already done). AF modes, and everything else require a trip to the menus or "info" screen.


#62533 Camera lenses for the D3400

Posted by ScottinPollock on 29 May 2019 - 11:02 AM

You may eventually want to look at either a prime lens (non-zoom) or higher end zoom lenses that can be used in lower light and in general have both broader functionality and higher price tags.


I don't recommend spendy lenses on a D3xxx-5xxx body for the simple reason that it will be hit or miss as to how well they will focus.

These bodies have no facility to calibrate the phase detect autofocus with specific lenses, so it is a bit of a crap shoot to get any lens that will focus accurately. Of course you can work around the issue focusing in LiveView, but I don't imagine many shooters want to have to enter that mode when they're using big, fast glass.


#62532 Zoom and/or Telephoto and 1.8 Advice for D3400

Posted by ScottinPollock on 29 May 2019 - 10:47 AM

I haven't used either of those two lenses (I did have the previous 24-120 and it was a dog, even on a 6MP sensor), but no... there is no sacrifice to using FX lenses on a DX body, other than size, weight, and sometimes cost.
 
In fact, since your only using 66% of the image circle of an FX lens on a DX body, corner sharpness is usually better.

#62281 Getting them "Tack Sharp"

Posted by ScottinPollock on 13 May 2019 - 03:53 PM

TL;DR: Use Live View on your DSLRs for tack sharp still lifes.
 
So coming back to my Nikon gear after around six months with the Lumix G9 (IMHO... the fastest, most accurate auto focusing camera for still subjects to date**), my first results were disappointing at best.
 
I was taking some stills of my house and some landscaping work being done and was disappointed in the soft images. These images were focused on the rather neutral gray siding of my home, or on foliage of cedar trees around the property. Something the G9 would have handled in stride, but a D7200 struggled with.
 
After quite a bit of experimentation, I discovered all the soft shots taken with the Nikon could have been sharp had I used Live View's contrast detection auto focus (the same method the G9 uses). Using the viewfinder and the Phase Detect method used with it can be hit or miss, depending on the contrast and lighting presented in the target. This is undoubtedly why I felt I saw so much more "pop" when I first started using the Panasonic mirrorless system. I thought first it must have been the lenses or sensor, but eventually discovered it was simply focus accuracy. I now fully understand why Panasonic wants to continue to develop their DFD CDAF focus technology over Phase Detection, even in the light of it's weaknesses (speed when tracking, hunting in video).
 
So after almost 4 days of testing, I can say that if light is good, and the focus point in the viewfinder is on high contrast areas (like engraving on metal), you can obtain the same level of accuracy as LiveView's contrast detection. But if not, you may get close, but you will have considerably more variation from shot to shot.
 
**Now I'll be the first to admit that PDAF can be faster at acquiring focus in a variety of situations due to it's instant computation of the focal point and focusing the lens on it in one step, especially in video where the back and forth of CDAF (even with Panasonic's DFD tech) is especially visually disconcerting... it is not as accurate. It can seem so with things like BIF and other fast moving objects, but that is a matter of timing, not absolute accuracy. PDAF is guesswork to a large degree, and CDAF is confirmation.
 
One last thing is that there is of course fine focus tuning available in-camera for the off sensor PDAF array with various lenses/focal lengths. I tested a number of lenses and can say that while that may have narrowed the margin I observed between PDAF and CDAF, it did not account for the variability of focus accuracy from shot to shot under PDAF.
 
So if you're doing macro, product, even portrait photography... try firing up that back screen and autofocusing with it. I'd be interested in hearing about your results.



#61613 FastRawViewer - Updated - On Sale

Posted by ScottinPollock on 12 April 2019 - 12:13 PM

If you shoot raw (or avoid it because it takes too long to cull your photos), you owe it to yourself to check out FastRawViewer.

This is an incredibly well thought out tool that makes picking your keepers and moving them to your storage faster and easier than any other tool out there (IMHO).

Fifteen bucks until Sunday.


#61544 D5500 acting weird - deliberately going out of focus

Posted by ScottinPollock on 09 April 2019 - 03:25 PM

Unless someone has another solution, I'm thinking that it's time for a trip to the waterfront (a grave for the camera) and then a trip to the Sony store; can't see buying another one of these.


Well this is indeed not a problem with mirrorless as the focus is determined at the sensor. And while Sony probably has the best on sensor phase detect system out there right now, the new full frame mirrorless glass is stupid expensive (not just Sony, but Nikon, Canon, and Panasonic too).

I chose to go Panasonic M43 as the glass is great and reasonably priced. Plus Panasonic has the fastest, most accurate contrast detect AF on the market. Probably the best there is for static scenes, but not so much for tracking moving subjects.

It really is about the kind of photography you do as to which models will address it better.


#61401 D5500 acting weird - deliberately going out of focus

Posted by ScottinPollock on 03 April 2019 - 02:39 AM

if it was working fine and now isn't, it isn't a firmware issue. In fact, introducing another variable at this time is not good troubleshooting practice.
 
Does this happen with more than one lens?
 
I would first suggest cleaning the contacts on both lens and camera.



#61359 D500 - Focus Setting for Video

Posted by ScottinPollock on 01 April 2019 - 04:23 AM

I am afraid Nikon DSLR continuous autofocus in video is pretty poor. The reason is that it uses a rather rudimentary contrast detect focus algorithm instead of the advanced phase detection system used for stills.
 
You'd be much better using a mirrorless model like the Z6 that has phase detect points on the sensor.



#61358 Vertical Bands

Posted by ScottinPollock on 01 April 2019 - 03:58 AM

The LEDs flickered at a frequency that alternated with the scan rate of the sensor. If you were using silent (electronic) shutter that would have exacerbated it greatly.




#61330 Shooting Indoor Sports (Basketball)

Posted by ScottinPollock on 29 March 2019 - 02:39 PM

The three main factors for freezing motion are focal length of your lens, distance from your subject, and the speed of your subject. For example: you need a much higher shutter speed for college athletes than grade school girls, or with a 200mm lens than a 55mm (given the same distance).

Given the specs of your camera and lens, you can calculate what's necessary for any given speed and distance using a little trigonometry. I have an article and spreadsheet that will let you plug in the numbers to see the results.


#61299 Looks like my new home

need to see how long i can delay sleep for.

 

Up to 10 minutes… or you can turn it off entirely.




#61294 Looks like my new home

Posted by ScottinPollock on 28 March 2019 - 11:43 AM

I snagged a G9 last year and have rarely picked up one of my Nikons since. It is not without its quirks (see my what's wrong series of videos), but currently there is not a camera out there I would trade it for.
