Nikon D750 Review

Image © NikonUSA

Background


The decision was made March 2018. The decision that I didn't want to admit.  My D700 was not cutting it anymore.  Before you go all crazy on me, hear me out.   The D700 is a great camera.  It was the camera that got me into my first FX size sensor.  It used the same batteries as my D300, had the same layout and could use the same battery grip.  Everything at the time made sense.

I needed better low light performance. The D700 was newer than the D300, has a larger sensor and similar performance.  It did everything I needed it to do at the time. It was a revelation and it served me well for many years.  It never had a hiccup, issue or failed me in any way mechanically.

Time moves on, D300 could use an upgrade and it was replaced with the D500.

Yeah....now we look at the D500 against the D700....and it doesn't sparkle as much as it used to.  IQ we are looking at something very comparable.  Let me repeat that a different way...the D500 APS-C (DX) sensor was performing on equal footing with the D700's FX size sensor.   On top of that, you also have newer imaging tech, better AF performance and more FPS for those times when you need that.

Still...that may not be enough to justify a D700 upgrade.  We head back to March 2018.   We are covering the Arnold Fitness Expo.  Hollywood Casino hosted boxing matches there.  Low and tricky lighting, a place where the D700 should excel.

To my surprise the D500 was out performing the D700 in those dark lighting conditions.  Why?  Metering.  It came down to metering.    The lights in the venue were often firing directly into the frame and the D700 was often fooled.   Depending on where you need to move and each scene being different from one part of the ring to the next, you need to be able to rely on the metering to help you out.  The D500 ate the D700's lunch here.

After that weekend event, I started looking at an upgrade. The logical place if I wanted to stay FX was the Nikon D750.

Handling/Weight/Size

Size of the D750 is just about right for me.  It has a great grip and handles the larger lenses well.
The grip is deep and allows for a confident grip, even holding on to it one handed with a 70-200/2.8 lens attached.

It is a smidgen smaller in all dimensions than the D700, and it is lighter as well.

I'm still not a big fan of the was you switch about AF modes, having to press in the side button and then turn the dials.   I'd rather have the old 3 position switch, but I've gotten used to it since that is the system used on the Df and D500.

All the buttons feel quality.  I wish that the D750 had the thumb stick on the back for adjusting the AF point.

The rear LCD is great for reviewing images. It is also articulating so it can be tilted at an up and down angle.  Great for those times when you want to shoot at unconventional angles above or below you.

The shutter mechanism also sounds different than the older Nikon DLSRs I have.  It sounds and feels more dampened but has a bit of a "twang" sound to it.  You don't really notice it until you shoot in a very quite environment.

While not a huge jump over the D700, the D750 metering is leaps above.  Shooting in difficult situations that are severely backlit or when light sources are coming directly into the camera, the D750 handles them more like the D500 does.  Thank you for that upgrade Nikon!

Base ISO is down to 100 now and the high ISO usability is now way higher.  You can get some great images at ISO 12,800 and 25,600.  ISO 6400 through is very clean in comparison to the D700.  I did not go over ISO 6400 on the older camera.

Dynamic range is also excellent and the files are rich in data so doing post processing has a lot of latitude, even in JPG files.

Auto Focus

AF here is basically the same as the D700 or D300.  That is not a bad thing.  The AF on those cameras is very good, predictable, rock solid.   It is not the phenom that is the D5/D500, but it is still going to get you where you need to be, just with a little more effort than the D500 requires.

One thing that I did notice is that I needed to auto focus fine tune every lens I put on the D750, except the Nikon 50mm f/1.8D.

The Nikon 35mm f/2, 24-70/2.8, Tamron 70-200/2.8VC all needed an adjustment.  Not much, between -2 and -5, but it needed it.

This is the first camera that I needed to use that feature.

In low light, the D750 also has an advantage over the D700.  It focus' more confidently in lower light, with less hesitation.  It also does not need as much light to AF.  Another great improvement over the older brother.

Video

You have a basic implementation of 1080p video here.  Nothing surprising.  It is there when you need it.   The camera includes mic input and headphone monitoring jack.

Battery Life

Powered by the EN-EN15a battery, it is rated at around 1400 shots per charge.  Plenty enough for all day shooting if needed with normal use.  I'm sure it is less with a lot of chimping or using the Live View or recording video.  This camera is so power efficient, it will last for DAYS!!


Other Misc. Items of Note

There are no regrets on upgrading the D700 to the D750.   It is an upgrade in all the areas that I needed it to be.   It performs well and the battery performance is phenomenal.  It doesn't hurt that it can also use the same batteries as the D500.

Right now, I feel that the Nikon D750 is the best affordable FX camera in the lineup.  The only way you could do better is spend the extra money on a D4 or D5.  If you are Ok with DX size sensors and need just that bit more AF performance and faster burst rates (10fps), then the D500 is where you should look, even though it has slightly poorer battery performance.

Tamron 28-200mm f/3.8-5.6. My FIRST DSLR Lens

Background

Another trip into the "way back machine" and here we have my very first DSLR lens I ever purchased.   The Tamron 28-200mm f/3.8-5.6 Di.   After having just purchased a Nikon D50, I needed something other than my old Nikon N90s kit lens, the 35-70/3.3-5.6.

Just starting out in the photography game, you don't always have the money to get a matching Nikon lens, so Tamron again to the rescue with a budget friendly super zoom.

Thankfully, at the time, I had no frame of reference to know what better was.  Honestly, for years this lens kept me moving forward.  Kept me learning and started me down the path.  Even for all it's failings, I got to give it properly respect for being there.

Handling/Size/Weight

This lens was built for 135 film camera, and just so happened to also be Nikon digital SLR compatible.  Even so, it is a relatively smaller lens considering the 28-200mm range. 

You also need to consider that the camera I was using it on, the D50 is an APS-C (DX) sensor.  SI your wife end is really a field of view of 42mm.

The zoom ring is smooth on this lens and it does telescope out, so you needed to be aware of that when using it near glass or people.

I don't remember it being particularly heavy either, so that is another plus.

I didn't really down lot with manual focus back then, but what I do remember is that the focus ring was a bit wobbly, but sufficient for adjusting as necessary.

Image Quality

The old saying that lenses are at their best clicked down a step or 2 hold true for this lens.  It is better side open on the wider end than the longer.

Plenty of distortion too, but nothing that post processing software could not fix.  It is not the best resolving lens, but given the target cameras it was placed on being 6mp (D50) and 12mp (D300) respectively, it was more than enough.

Focusing

The focus was always very accurate, but the speed was lacking like most Tamron lenses of that generation.  It would often hunt and rack focus, but when it locked in, it was plenty accurate.

Bottom Line

What a walk through memory lane.  Not sure why I didn't this lens as a review, perhaps it was just to allow for some nostalgia, dig up some old pics and remember the simpler time of shooting without a bag full of lenses, a deadline of the stress of a paying client.

Given the quality choices that are available today, I do not see any compelling reason to use this lens but give us another 15 years and we just might be saying that about the lenses we have right now.

Anyway, just remember to sit back and review and remember how you used to do things.  Sometimes we leave behind techniques and methods that could benefit us, or remind us of the mistakes we made and to not make those again!   Learn from history.

Tamron 17-50mm f/2.8 Review - A Lens From Yester-Year

image © Tamron USA


Background

Reaching back into the archives, I've never really reviewed for you all my very first "Pro" workhorse zoom.    I say "Pro" because back then, if anything was f/2.8 constant aperture, we all called it that. 

The Tamron 17-50mm f/2.8 was my first lens I purchased specifically for my photography business.  I wanted something versatile and with a fast aperture.   Money being scarce, you sometimes take chances on things....and that is what I did with the Tamron 17-50/2.8.

Shooting wide open at f/2.8 on an APS-C sensor


Handling/Size/Weight

Tamron always surprised me in how they could make relatively equivalent lenses for less money as well as smaller size and lighter weight.  The 17-50mm was no exception as compared to what Nikon had at the time, the 17-50 just made a lot of sense.  This lens was put to work on the Nikon D50 at first, then later on the D300.

It balanced well, and relatively was a light lens that wouldn't burden you if you needed to use it all day.

The focus ring and zoom ring were covered in a rubbery coating that helped when shooting in the cold.  No frozen fingers.

Product photography, sure the Tamron could do that too!

Image Quality

Right off the bat, the f/2.8 aperture was a blessing and a curse.  You wanted to shoot there all the time because that is why you bought the lens in the first place!  However, f/2.8 is where this lens is at its worst.  Don't get me wrong, it is usable, but it was not the sharpest there and you had to make sure that you nailed focus because of the shallow depth of field.   Even on an APS-C sensor, f/2.8 can be tricky if you are shooting portraits.

All you really need to do, though is stop down to even f/3.2 and the lens sharpened right up, and in spades!!

In the early DSLRs, you did not want to push the ISO very far.  The D50 was about ISO 800 limit for me and the D300 was ISO 1600...maybe 2500.  so having something better than the kit lens apertures was refreshing.   My first lens for the D50 was a Tamron 28-200/3.8-5.6.  This was a 135 sensor size lens, so right away your field of view is going to be 42mm.

The Tamron, starting at 17mm, gives you roughly 25.5mm.  A big step up in the width department, for sure.

I'd love to get my hands on one of these and see how the IQ stacks up with the 20mp sensor on the D500 I have.  The 6mp and 12mp sensors worked quite well with it.

stopping down to just f/3.2 and the sharpness ramped up nicely.

Focusing

The focus was always very accurate, but the speed was lacking.  Quite slow, which made tracking moving subjects a challenge and it was very noisy.   This lens did not sport a silent motor.  It was driven by the old screw and gear system.

It did not have a full time override of the AF either, so going from AF to MF was a 2 step affair, switching the lens to MF as well as the camera to MF.

An unsung point of the 17-50 was how close it was able to focus.  Before I purchased a dedicated macro lens, the Tamron served as a pseudo-macro.  It was able to get close enough and with some cropping made for some great close ups.

Below are some examples of this lens used for reportage and portraiture.




Bottom Line

This is one of the lenses that helped me go from mediocre snap shooter to producing professional results.  Yes, I know that gear is not what makes you a pro, but having gear that allows you to make the images you envision easier...well, that is what we are looking for here.

I still have fond memories of that Tammy lens.  I can still hear the grunting and grinding as it racked focus, feel the rubberized zoom barrel.  As I went back and looked at the images I made with that lens, it reminded me of a much simpler and less expensive time.   I was just a noob back then trying to find out where I fit in.

With the Tamron 17-50mm f/2.8, I could fit in anywhere.  It was very versatile and the workhorse I needed at the time.
