85 mm f/1.4 lens

 

My new 85mm f/1.4 lens came earlier this week.  It is manual focus and manual aperture.  Kind of like going back in time.  After focusing on the subject, the viewfinder meter has an exposure indicator, and exposure is controlled by either changing the shutter speed or the aperture.  However, this is not even a lens that stops down to the chosen aperture when the picture is taken.  When you change aperture, you see the results immediately.  So, stopping down makes the image in the viewfinder darker.

This is a “portrait” lens because the wide aperture gives a shallow depth of field. The whole idea of this lens is to focus on one spot and almost everything goes out of focus but that spot.

I went to Indian Spring Park yesterday and took some pictures with it.  I was not all that thrilled by them.  The truth is, most were not properly focused.  Although, the couple that were, had a very sharp focus.  So, I went back today.  I did a little better. I took about a dozen pictures, and all but two were in really good focus.

Lone Star Rally Equipment Statistics

Using Aperture Inspector, here is a quick analysis of the equipment I used at The Lone Star Rally. I took 152 (63%) images with the a700 body and 89 (37%) with the a550.  I used three lenses.  I took 139 (58%) pictures with my old Quantaray Tech 10 70 – 210 f/2.8 lens.  I took 73 (30%) with my Quantaray 18 – 35 f/3.5 lens, and 29 (12%) with my Tamron 90 mm f/2.8 Macro.

Lens Repair Followup

My 70 – 200 f/2.8 lens somehow stopped working properly.  So, I sent it to Tamron.  They received it and before it could be repaired, Sandy hit.  So, it spent a week there.  I called them this morning, and they have repaired it and shipped  it yesterday.  So, I will have it Friday.  Great news!

Fast Glass

I mentioned before that the wedding photography seminar we watched featured a photographer who used three prime and one zoom lens.  The three primes were a 24 mm f/1.4, a 50 mm f/1.2, and an 84 mm f/1.4. Everything she shot was with available light.  Well, now I appreciate why she used such fast glass.

I used Aperture Inspector to look at the aperture and iso I used for the wedding last Saturday.  91%of the pictures were take with apertures less than f/5. 40% were taken at iso 400, 27% at iso 800 and 6% were taken at iso 1600.  86% of the pictures were taken at shutter speeds faster than 1/60 second.

Faster glass would mean wider apertures, lower iso values and faster shutter speeds.

I found a Rokinon 85mm f/1.4 on eBay.  It is manual focus and manual aperture.  So, it will take some experimenting.

Aperture Inspector

There is an application called Aperture Inspector that allows you to obtain a variety of information about your equipment use for the pictures in an Aperture Library.  When you open it, you link it to an Aperture library.  You can set a specific date range.  It tells you what camera bodies you used, what lenses you used, if they are zoom lenses, what focal lengths were used, what apertures were used, what shutter speeds were used, and what iso settings were used. There is also information about filters.

Sandy

Hurricane Sandy has hit the east coast.  Last week, I sent my Tamron 70 – 200 f/2.8 lens in for repair.  I sent it to Commack, New York.  Commack, New York is on Long Island.  I really hope that I will eventually get my lens back.

Lens Repair

I got an email from Tamron.  They want $225 to repair my lens.  They will disassemble it, clean it, repair and damage, put it all back together and calibrate it.  I wish it were cheaper, but I don’t have any other choice. A new lens would be almost four times that much.  They promised a turnaround of three business days.  Let’s hope that comes before Sandy hits the east coast.  I have visions of my lens sitting in a destroyed building.

Camera Bracket

Cindy emailed me today and asked if I had and use a camera bracket.  She has asked me to shoot a wedding with her on Saturday and someone told her she needed to use a bracket.  I told her I do have one, an Alzo Flip-Flash Bracket (http://www.alzodigital.com/online_store/flip_flash_bracket_digital_camera.htm).  I have never used it, but I will probably give it a try on Saturday.  My problem, though is I do not have a synch cord.  So, I got on to Amazon and ordered two of them.  They should arrive by Thursday, in time for the wedding.

Lens Problem

While shooting in Atlantic City, I had problems with my 70 – 200 mm f/2.8 lens.  It would not focus at distance when at the shorter focal lengths.  Additionally, I had noted that the focus was not spectacularly sharp when the lens was wide open.

So, I am sending it to Tamron for service.  I have never sent a lens in for servicing before.  So, I do not know what to expect. I sent it via UPS today and they say Tamron should get it on Thursday. Tamron claims a three day turn around for repairs.  So, I hope I will have it by next weekend for the Lone Star Rally.

Lenses

I watched a wedding photography seminar this weekend.  She shoots using four lenses – 3 primes and 1 zoom.  The zoom is a 70 – 200 f/2.8.  The primes are a 24 f/1.4, a 50 f/1.2, and an 85 f/1.4.  She shoots everything available light, only using flashes rarely to fill.  Thus the need for such fast lenses.
